The Cervelo P5 – Worth the Wait

Wednesday, January 18th, 2012

Shrouded in secrecy, the new Cervelo P5 launch has been full of speculation for almost a year now.  Well the speculation is finally over and the results are really good.  The 2012 Cervelo P5 is now an official model and we are taking orders for first shipment delivery now.  If you want to be on a P5 this coming season, get your name on one now as they are just about guaranteed to sell beyond the initial production.

Some highlights:

  • TT and TRI frameset models.  The TT model is UCI legal, the TRI model maximizes aerodynamics, but is not.  The UCI compliant TT model is only available as a frameset at $4500, which includes the rear brake.    The top of the line TRI model is available as a $6500 frameset that includes an impressively adjustable and aero new bar from 3T called the Aduro.
  • There are two pre-built bike options currently – mechanical Dura Ace ($6000) and Di2 ($10,000).  The mechanical Dura Ace model uses the UCI compatible “P5-3″ fork while the Di2 version includes Magura RT-8 carbon brakes, removable fairing, 3T Aduro bar and the deeper “P5-6″ fork.
  • “Magura RT-8 brakes” = carbon hydraulic road brakes and the P5 is the first production aero bike to offer hydraulic brakes.  This could be a game changer and a sign for all TT bikes in the future as we expect these to work extremely well.  The prebuilt mechanical Dura Ace bike comes with the RT-6 hydraulic brake, the alloy version of the RT-8.
  • A third party company will offer a variety of add-on integrated storage solutions for the P5.
  • BBRight.   Cervelo’s smart asymmetric bottom bracket/chainstay design is now on the P5 and that means even better drivetrain response.
  • Aerodynamics.  In a few words – “better than ever”.   The P5 takes the already impressive aero numbers of the P4 and improves upon them in every way.  Thankfully, the P5 does this without a lot of the limiting complexity found in most of the integrated aero bikes on the market right now.
  • Simplicity.  Unlike a number of competitors, the P5 is compatible with any standard aerobar/stem and doesn’t use much of anything that requires special componentry.   Another benefit is that there are no mechanically proprietary parts, meaning that you can get parts for the P5 anywhere in the world that carries standard bike parts.  This is something many of the P5′s competitors cannot claim.  From what we’ve heard, it is awful having your “super bike” out of commission because you can’t get a proprietary bolt or the like when doing in Ironman in Spain…
  • Storage.  A range of integrated aero storage solutions for nutrition, hydration and tools will be available.
  • Geometry.   A wider range of athletes will fit on the P5 well compared to the P4.
  • A tri bike first and foremost.  While previous Cervelo aero bikes were designed with TT use as the primary focus and with tri as the secondary, the P5 shows that Cervelo is focusing 100% on making the best tri bike they can.   From fit to features, this bike is a triathletes ride first and foremost.  Luckily, the TT abilities of the P5 were not harmed in doing so – the P5 is still going to make an excellent TT specific bike.
  • AeroZone Engineering takes into account that all aspects of the bike and rider interface are unique and require small detailed solutions to maximize the aerodynamics.  From small sweeps at the end of the top tube to the unique shape of the seatpost, these details were created based on the fact that a dynamic rider is the major aerodynamic impediment and you have to minimize the rider’s negative effects to maximize aero time savings.

With the P5, Cervelo managed to progress while going back to basics and simplifying many things from the P4 – a notable accomplishment.  We look forward to getting our first one in March and finding out more!

SHIMANO ULTEGRA Di2 – A QUICK REPORT

Thursday, December 15th, 2011

SHIMANO ULTEGRA Di2  - A QUICK REPORT

By Jim Weaver, Service Manager

Fit Werx, VT

 

I just finished building two bikes with the new Ultegra Di2 electronic shifting group.  One bike is a very nice Serotta Ottrott SE.  Saying an Ottrott SE is “very nice” is redundant, as I cannot imagine an Ottrott that is not “very nice”.  But I digress.  The other bike I finished is a Cyfac Spirit, with internal cable routing specific to Di2.  Cyfac may be an unfamiliar name to riders in the United States; they are a custom frame manufacturer from France that builds using carbon fiber, titanium, aluminum, and steel, in a very wide variety of frame designs.  The Spirit is one of their steel offerings and we were impressed with the quality and finish and we liked that it was a bit out of the ordinary.   Well, “out of the ordinary” is really not the right term; Serotta, Parlee, Guru, Independent Fabrication, Seven, or Moots, other hand built manufacturers we represent, are definitely not “ordinary” bicycles.    Perhaps I should use the adjective “rare”, “scarce”, maybe even “esoteric”, rather than “out of the ordinary”.  The bottom line is that if you are riding a Cyfac, odds are that you will have the only one on that next group ride.  But again, I digress.

The topic at hand is a first report on the Ultegra Di2 group.  From a mechanic’s perspective, the electronic group goes together fairly easily, arguably slightly easier than with Dura Ace Di2.  If the bike has internal cable routing, the Ultegra Di2 is much easier to build than the Dura Ace as the cable junctions for Dura Ace require the use of heat shrink tubes around each joint to make them water-tight.  The Ultegra connections are water-tight without the need for any additional sealing.  This is much easier for me, the builder, not to have to mess with using a heat gun, in tight spaces, around painted surfaces.  Presumably Shimano will adopt this type of connection on the next generation of Dura Ace components.

The setup and operation of the Ultegra is the same as the Dura Ace.  Initial alignment of the derailleurs is very easy, and the process is the same for both groups.  I did not notice any difference between the two when riding.  Shifts are spot on, no misses because you did not swing the lever far enough, and are totally predictable.  The front shifting is of particular note, being very quick, no misses, no rattling, and with the entertaining and functional computer controlled automatic trimming to prevent the chain from rubbing the derailleur.  These same comments apply to Dura Ace as well.  The only drawback I see to Shimano’s electronic shifting is the inability to shift more than one cog at a time, but if you move your finger rapidly this doesn’t seem like much of an issue.

Unfortunately, my rides of both Di2 systems have been limited to brief test rides of new bikes to insure that everything is working properly, and that the build of the bike is correct.  Perhaps back-to-back, longer rides would reveal operational differences between Ultegra and Dura Ace that I could not detect.   It is worth noting that there are some other notable “non-operational” differences between Ultegra and Dura Ace Di2.   All of the Ultegra parts, particularly the front and rear derailleurs, are noticeably heavier than their Dura Ace counterparts – 263 grams, about half a pound.  For high performance bikes these days, half a pound is a lot.  This being said, the Ultegra Di2 is only 80 grams heavier than the mechanical Ultegra group, so the weight penalty for going to electronic shifting is minor.  The Ultegra Di2 derailleurs are also larger and bit chunkier in appearance than their Dura Ace siblings.  The primary reason for the bulkier look is that the Dura Ace derailleurs use motors designed by Shimano specifically for that application while the Ultegra derailleurs use “off the shelf” motors in order to achieve significant cost savings.  I do not find the larger, bulkier look of the Ultegra to be a significant detraction, but they don’t appear quite as refined.  The battery is the same lithium ion battery as used in the Dura Ace group, and the battery life is predicted to be the same.  Shimano says the battery should last at least 1,500 miles.   Recharge takes 90 minutes, and the battery can be recharged 5,000 times.  That’s a lot of miles!

Simply stated, everything you have read about the Dura Ace Di2 operation applies to the Ultegra group.  If you want the ultimate, go with the Dura Ace for its lighter weight, better esthetics, and all the durability and bearing quality advantages that Dura Ace components offer over Ultegra in the long-term.  On the other hand, if you want the benefits of electronic shifting for half the price of the Dura Ace group, Ultegra Di2 offers a lot of “bang for the buck” and will likely be very popular over the next few years.

Coming Soon – Campagnolo Electronic!

Tuesday, November 8th, 2011

We’ve heard about it for awhile and seen it on pro bikes as far back as ’05 – now it is just about a full reality.  Campagnolo has journalists riding production Record and Super Record EPS Electronic shifting systems and it sounds like while it does many things Shimano’s landmark Di2 group offers, it also does some unique things all its own.   Initial reviews from Cycling News sound promising and it is some rumors slate it to start shipping as early as December…

Some Bike Bargains for 2012

Thursday, October 27th, 2011

One thing that is interesting about the current cycling marketplace is that there are some real opportunities showing up to be able to buy products that used to only be available at much higher price points for a lot less – there are some great values.   You can get the Ferrari for the price of the Corvette or the Corvette for the price of the Camaro.   Here are a few examples in both the road and the triathlon category:

Road

Felt Z5 & Z6: It was not that long ago where “entry level” carbon fiber bikes were running over $2500.   Today, you can get a Felt Z6 for $1699.   Also, for $2299 you can get a Felt Z5 with the next level up carbon fiber and a full Shimano 105 group (Shimano’s first group offering their full range of features and designed to be ridden regularly).  The bottom line is that the amount of bike that you get for your money has never been better.

 

 

Cervelo S5 Rival - It used to take years for technology to trickle down through the price points, now you can get very similar technology to the very top of the line for a lot less.  The Cervelo S5 Rival uses the same frame as the Team, but with a little heavier fork.   While not a cheap bike, considering it offers Pro Tour technology at $3800, it is a bargain.

 

 

Seven Axiom S – Titanium is a great material to build bikes, it lasts forever, doesn’t corrode, doesn’t require paint, can be rider tuned, is light…   There isn’t much that it doesn’t do well when in the hands of a good frame builder.   For around $5000 (frame $2800) you can get a well equipped Seven Axiom S and have a bike you can keep forever.   Over 15 years, a Seven Axiom S is under $350 a year, less than half of what most people pay for cable TV and a whole lot healthier.

 

Di2 Ultegra – Last year, to get Di2 electronic shifting, you had to spend around $10,000, now bikes like Felt’s Z3 at $4999 do so at half that.   Another option is Cervelo’s S5 Di2 Ultegra which, at $6000, offers a Pro Tour level frameset and Di2.

Triathlon/TT

Parlee Stock TT: The Parlee Stock TT is unquestionably one of the very nicest riding and best fitting production tri/TT frames on the market.  Parlee is a specialty builder and their experience in carbon manufacturing is evident throughout the fabrication and design of the Stock TT.    A Parlee Stock TT frameset is regularly $3700 and the complete bikes normally start around $5000, but we’ve made a special buy and have a limited supply of Force and Ultegra equipped Stock TT models available for well under $4000 -  $3899 on either, to be exact.   This means for just $199 more than what the frameset normally costs, you get a complete bike, and a complete bike with a great level of componentry.   That is some big savings.

 

Guru CR.501: Full custom frame geometry that guarantees it fits you ideally and gives you the widest possible adjustment range, your choice of colors and finish, rider matched handling characteristics that eliminate compromises in stability, discipline specific (TT or Tri) geometry, made in North America…    The CR.501 might be Guru’s first level of frame, but it is far from entry-level and it should not be compared to the entry level models form mass produced manufacturers for this reason.  So, while you can get Spec

ialized Transition for less, that is like saying a Specialized Transition is equal to a Cervelo P3 and it simply is not.   The Guru CR.501 is much more comparable to the higher end offerings from most companies when it comes to material quality and fabrication approach.    So, you don’t need to pay more to get all those features listed above that do not come on production bikes.   We took the component group off a Cervelo and put it on a CR.501 and the price came out within $100 of the P3 at $3700.   Unlike mass produced bikes, we can all but guarantee that the CR.501 comes in a size that fits you as the $3700 includes full custom geometry and there are some great looking finish options that give it some personal flare as well.

If you have been fit at Fit Werx we have your fit information and can help you find the right matches for your riding position and budget, just contact us with questions!

Reynolds RZR Initial Review

Reynolds RZR Wheels – Review and Impressions
By Jim Weaver
Service Manager, Fit Werx VT

We have had a set of Reynolds’ top-of-the-line wheels, the Reynolds RZR, in the shop all season for demo, many of you have seen and admired them.  After wrestling them away from Ian, I had the fortunate opportunity to ride these wheels for a weekend recently.  Ian has ridden these wheels on his bike all season and he can give a more detailed analysis.  However, here are my impressions of these wheels.

Let’s get this out of the way first – I want these wheels!  But I am getting ahead of myself.   First some, general information about these wheels.  The Reynolds RZR offers a tubular rim, hub and spokes that are constructed of a blend of carbon fiber and boron fiber.  The carbon spokes are of an N.A.C.A. symmetrical airfoil shape, not simply flat bladed spokes.  The rim section is 46.5 mm deep, and 21.25 mm wide; the rim profile is nicely aerodynamic, incorporating  Reynolds’ patented “Swirl Lip Generator”, a small raised edge which helps air flow reattach to the rim as it travels over the trailing edge, thus reducing turbulence.  The rear hub has 3 flanges, so that one set of rear spokes transfers power directly from the rim to the hub, rather than laterally from the outside to the rim, creating a stronger connection between hub and rim.  Bearings are ceramic.  The skewers are titanium.  The Reynolds RZR wheelset weighs 968 grams.  Yes, you read that right.  968 grams is not the rear wheel weight, but rather the weight of the entire wheelset!  These wheels rival the Lightweight Obermayers as the lightest aerodynamic wheels on the market.

I have ridden other wheels in the same category as the RZR as part of test rides of client bikes, Lightweights for one.  But this has primarily been on shorter rides, this was the first time I really got to ride a pair of such wheels for an extended time.  I had some, baseless, preconceived notions about what to expect from the Reynolds RZR.  I figured that these wheels would be fast in a straight line.  Given that these wheels are so light, I expected that they would be either very stiff and a bit harsh, or much too wimpy and soft.  I expected them to be twitchy or a bit unstable, particularly on descents.  My first notion was correct – the Reynolds RZR is fast.  Very fast.  This became apparent immediately upon exiting my driveway, standing up to accelerate up to speed.  My thoughts went something like this, “Who’s pushing me?”, “Ah, nobody.”, “Very cool.”  With so little rotating weight, the bike simply shot forward, accelerating very quickly.  On a climb, the lightweight of the Reynolds RZR makes a very noticeable difference, allowing me to hold a higher gear for a longer time.   In that I climb like a stone, this was much appreciated.  This performance confirmed that light wheels are more important to climbing than a light frame.

Given the aerodynamic shape of the rim and spokes, and minimal effort needed to keep them rotating, I expected the wheels to be fast in a straight line and they were.  These observations may seem obvious.  How could an aerodynamic, extremely light, aerodynamically shaped wheelset not accelerate quickly, be fast in a straight line, and climb like the wind?  However, what is not so obvious are the other handling characteristics of these wheels.  My first foray down a hill was tentative.  My confidence in these wheels increased with each descent, until I was descending with the same verve as my Mavic Ksyriums. Contrary to my expectations, the Reynolds RZR were a rock solid and stable wheel, which was particularly noticeable when descending.    The Reynolds RZR are also a quick-handling wheel, responding to my inputs without hesitation.  Some of this has to do with the fact that the RZR is quite laterally stiff.  I am not particularly light, pushing the limits of the recommended maximum rider weight for these wheels, but even with that I could not detect any flex under stress, such as when climbing out of the saddle.  By the way, their recommended weight limit is 180 pounds.  This lateral stiffness did not translate into a harsh ride, however.  They rode very smoothly – at least on par with wheels like the Mavic R-Sys in terms of vibration damping.  In summary, the Reynolds RZR does everything very, very well.  And that is an understatement – these are arguably the best wheels available for a bicycle today.

Needless to say, these are not budget wheels.  As the old saying goes, you get what you pay for.  Greatness is not inexpensive, although cost does not automatically mean something is great.   Are these wheels worth the $6,000 price of admission?  Is a Porsche 911 worth that much more than a Miata?  They are both sports cars, right?  Are Wilson MAXX 3 stereo speakers worth that much more than a pair of Pioneer bookshelf speakers?  They both play music.  Is organic produce worth paying a premium over mass farm?  Only you as a prospective buyer can make that personal cost/benefit analysis.  I can state, without reservation, that there are substantial (pick-your-own-superlative adjective) benefits to these wheels.   Benefits that are unavailable from all but a very, very select few wheels on the market today.  It all depends on your perspective and passion – but rest assured that these wheels can change the way you think about riding and the way your bike performs.  So, anyway, as I was saying, I WANT THEM and I do think they are worth eating Raman noodles for a year in order to get!

Parlee Stock TT Review

Friday, October 14th, 2011

PARLEE STOCK TT IMPRESSIONS
By Jim Weaver, Service Manager
Fit Werx, VT

This is the story behind my acquisition of a tri bike frameset, and why I chose a Parlee Stock TT.  For those who do not know me, I am a very occasional triathlete, not trying to be competitive, just trying to stave off Father Time.  However, I have wanted a tri bike for some time, and have toyed with doing some of the Stowe and/or GMBC time trials locally.  I was using my 2003 De Rosa King road bike, cobbled together with a set-forward seatpost, and aero base bar and extensions.  It is a nice road bike frame, although now 8 years old and therefore a bit dated.  As a classically designed Italian frame, the geometry of this bike is not at all appropriate for a time trial position.  With all that weight shifted forward on a frame designed for a road position, handling was at best a bit twitchy, and on descents, sometimes scary.    Besides, I’m always talking about the benefits of tri bikes, so I should probably own one myself…   So, for the past year or two I have been considering the many options available for a tri bike.

As service manager here at Fit Werx in Waitsfield, I have had the privilege to build, and ride, many tri bikes, from the  entry level Felt S22, through the entire Cervelo line, the Guru tri bikes, and culminating with the most refined and exceptional riding tri frames in the world – bikes like the custom Parlee TT and  Serotta MeiVici AE.   From Scott to QR and Kestrel, I have also worked on many tri bikes from other manufacturers and thus have had the opportunity to test ride a wide selection of tri bikes from most of the major manufacturers.  While the custom Parlee and Serotta are extraordinary and highly desirable machines, truly the epitome of the art, and the Guru CR.901 is a wonderful frame, my rare forays into triathlons are limited to sprints, and maybe an Olympic distance someday and, if I do any of the local time trials, it will be simply for fun (if a time trial can ever be considered as “fun”), with no expectation of being competitive.   It’s greatly a matter of aerobic efficiency, which I do not have.  I therefore could not justify to myself, or my wife, owning one of the very best possible TT bikes – I therefore focused my search on the intermediate price range of frames.

I have built many stock Parlee TT tri bikes for shop clients, and have always liked them very much.  Our clients who ride this frame have always had very good things to say about this frame’s ride quality and handling and over the summer I built one for a client, in a frame size that was appropriate for me and took it for a test ride.  I thoroughly enjoyed my ride on this bike.   Because the bike fit me well, I was able to really pay attention to the frame’s ride characteristics.  The ride was very comfortable, stable and responsive, confirming everything we have said about this frame and our clients have reaffirmed.  Our daily manager and buyer, Bruce, also test rode this bike, and was similarly impressed.  I have a Parlee Z2 as my present road bike, one of their custom frames, and love the way it rides – I was leaning decidedly towards the Parlee TT as my future tri frameset.

I liked the fact that Parlee has a local feel to them, being based in Beverly, MA, and that they focus purely on performance oriented carbon fiber road and tri bikes.  Elsewhere in the website is a thorough discussion of Parlee, and why we feel they make such great bikes.  If you have not already read this review, check it out at http://www.fitwerx.com/product-reviews/bike-frame-manufacturer-profiles/parlee.  Also, I had the chance to visit the factory about a year ago and was very favorably impressed.  Bob Parlee, the founder and owner, was there on the production floor, working on a prototype of future models, so he has a personal hand in all their bikes, literally.  Parlee’s custom geometry bikes are fully constructed in this facility.  Their stock geometry bikes, the Z5, Z5 SL, and the stock geometry TT bike, are manufactured to Parlee’s exacting standards in S.Korea, in a small factory that specializes in detailed carbon work.  However, having worked on many, many carbon bikes, I have found the workmanship of the stock Parlee TT exceeds the carbon workmanship and finishing that I see on the frames from all but the very top custom frame builders; the build quality on the stock bikes even rivals Parlee’s in-house bikes.  The Parlee TT offers a wide variety of frame sizes:  Small, Medium, Medium, Large, and Extra Large and each of these frame sizes offers two head tube lengths, making for a total of ten effective sizes.  With most mass manufacturers, you are lucky to get five sizes, and from some manufacturers you only get three – small, medium and large!  As a result, the Parlee Stock TT frameset fits a wider range of riders than just about any other stock geometry tri bike; the only way you will get more fit options on a tri bike is to go with a fully custom bike, such as Guru, Seven, Parlee or Serotta.

The Parlee TT has all the “bells and whistles” that are now considered de rigueur for a quality tri bike:  airfoil-shaped headtube, downtube, seat tube, and seat post; internal derailleur and rear brake cable routing; rear brake mounted behind the bottom bracket, cut-out seat tube to allow the rear wheel to be brought forward for better aerodynamics, and horizontal rear dropouts that allow the wheel to be pulled in tight with the seattube.  Many, many bikes on the market have these attributes, but the Parlee TT goes well beyond these now common attributes.  For example, the seat post is a truly ingenious design, allowing for a wider range of saddle positions than any other seatpost that I have seen in my three years here at Fit Werx, and, of course, there is the ride quality.  Outside of the top custom Guru, Parlee and Serotta custom tri frames, this is the best riding tri frame that I have experienced.   After all, this is the little brother to the full custom Parlee TT, one of the top two best riding TT frames available (the other is the Serotta MeiVici AE).   The Parlee Stock TT shares Bob Parlee’s design philosophy and attention to ride characteristics with its big brother, making it an exceptionally nice riding bike.

Given all of these attributes, and my love of my Parlee road bike, I finally settled on the Parlee Stock TT.    I turned the big Six Zero in September, and decided that this frame would be an appropriate gift to myself.  Even better, my significant other enthusiastically agreed, as it relieved her of trying to think up something to give me.  Besides, she already has a tri bike.  So, I am now the proud owner of a new Parlee TT frame, and cannot wait to get it on the road.  Now for the decisions about the build kit!
