Bike Update

So last night, I took the Cervelo out for a short ride, and have determined that I still have some kinks to work out. Nothing show-stopping, of course, but still. Gotta be done before Wednesday's edition of the Black Dog Time Trial. Considering re-taping the bars and putting some gel inserts on them before then, too.

Been re-cabling the commuter bike, and ordered a mount for it so I can take the Garmin with me on my commutes.

I'm going to expand this section of the blog/site a bit, too. Going to include pics of the fleet, some routes in .tcx format that will be downloadable, and so on.

Tonight: work on bikes, session on the Wii Fit.
Tomorrow: easy recovery ride.

Bikey Bikey

So tomorrow, I am probably going to race the Black Dog TT. I use the term "race" loosely, as I won't even be close to competitive, what with my "extensive" training program I've undertaken this spring, and the aerodynamic 20-pound beer gut I'm toting.

Tonight, I'm heading out to Burnsville to give the course a quick drive -- I'm told that it's a mish-mash of potholes and meteor craters and I'm not sure I want to put the Zipps into that kind of a situation. I got a couch to buy in the next few weeks and am not big on the idea of having to shell out $250 to crash-replace a wheel.

While down there, I'm picking up my dad's old Peugeot, which I am going to park in the basement of my place. I've got some ideas afoot for what to do with it, but more on that later.

Tonight, I've got to get some minor maintenance work done on the fleet and gear:

  • the Salsa Campeon needs new brake pads on the rear -- it has for awhile now, it's just that the process of using a hammer to pound the Jagwire pads into the Zero Gravity holders isn't what I'd call a fun time
  • put the pedals back on the Cervelo
  • install speed/cadence sensor on Cervelo
  • wash my cycling clothes
  • clean out gear bag
  • tune up the Surly Cross-Check for commuting

Got to throw some stuff on MplsBikeLove and Craigslist tonight. Old cyclecomputers, a crankset/BB, and so on.

A Few Random Things

  1. I got the Ambient Web Metrics device partially built and embedded in this site. There's a write-up here. Every time you visit a page on this site, an angel gets its wings a white LED blinks. Pretty pleased about how it's going, but at the same time, it was supposed to be a while-Kate's-gone project. I'm saving the fine-tuning for that.
     
  2. Arduino (see "Ambient Web Metrics", above) is pretty awesome.
     
  3. Some woes with installing the FSA TT chainrings on the crank for my Cervelo. Remember my complaint about the P2C shipping with a compact crank? Well, when boy genius (me) ordered the chainrings, he didn't take into account that the cranks are a 110mm BCD, and the chainrings are a 130mm BCD. Ooops. Put crank for sale on Craigslist and Minneapolis Bike Love. Will roll proceeds into new crank.

Review: Cervelo P2C (Ultegra)

IMG_1453.JPG
The author's P2C, with non-stock Zipp 404 wheels and XLab SonicWing.

Based on two experiences surrounding this bike, I decided to purchase one via Cervélo's shop employee-purchase program. The first experience was getting eyeballs and hands on the Dura-Ace equipped model in our shop. The second was the thorough review written by the crew at Bikesport Michigan. This is my take on the bike, written from the POV of a mechanic and a rider.

Unboxing & Assembly

This is important to bike mechanics, but it's equally important to those riders that maintain their own gear. While that's a smaller percentage of the population, it's important to be aware of what you're in for.

Unboxing the P2C was pretty much like unboxing any other high-end road bike. The bike inside is far less assembled than a lower-end (think $279-$600) hybrid or mountain bike, and is going to require some time to build.

Having watched our (former) service manager struggle through part of the P2C assembly, I can say that the one part that will slow you down is running the cable guides. In fact, getting the derailleur cables run was a process that required some serious McGyver tactics, and has sparked me to write a HOWTO guide, which I'll be posting later today.

The only other issue was securing the bike in a workstand. Trek makes an adapter for its aero seatposts that allows you to clamp the bike into a standard workstand clamp. This is not an option on the P2C, due to the sheer size of the post. Whether or not Cervélo manufactures a solution for this is unknown to me, and I didn't think to ask. I merely resorted to turning the workstand clamp horizontal, resting the top tube on it, and not closing the clamp, for fear of damaging the carbon.

The only other issue I encountered during the build process was the need to cut down the seatpost slightly. I Googled around and was able to find discussions on Cervélo's forums regarding doing this to a P3C seatpost (the same post, as far as I know), and nothing was posted by Cervélo contradicting the advice. Thus, I approached the problem like I did with the carbon steerer tube on my Salsa -- a dremel tool with a diamond blade, a facemask to prevent a short-term future of black mucus, and a bit of trepidation.

All in all, the build process was trivial, with the exception of the running of the shifter cables through the frame. I'm sure it would be a slight hit in frame weight, but I'd really like to see Cervélo add internal guides to future versions so that I, as a mechanic, don't need to spend more than four hours struggling to accomplish what would be a two-second job on other non-internally routed bikes.

General Impressions

Once I had the P2C unboxed, out of the stand, with the basic parts on it, I stopped to admire the thing. Looking straight at the front of the bike, my first impression was, "Damn, this thing is skinny!"

And it is -- look at the bike from the front, and it seems to disappear. This, I'm sure, is due in part to the shaping of the head tube and the narrowness of the Wolf CL TT fork. But front-on, wow. Even with a 1 1/8" steerer tube in there, this bike gives the impression of being more skinny than an ancient steel frame with a 1" steerer.

From the side on, you get an idea of where the stiffness of the bike comes from. While the sleek/narrow appearance continues around the top tube and back to where it meets the seat tube, following the down tube's line to the bottom bracket cluster reveals a figurative blossoming of material. The bottom bracket, and chainstays, like on other Cervélos, can be described, politely mind you, as beefy. And yet, the bike doesn't end up looking awkward or goofy -- the parts of the bike are designed they way they need to be -- a stiff lower half for power transmission, with careful attention to aerodynamics in the head tube, seat tube, and down tube -- all the points where the bike meets wind. And even with these disparate parts, the P2C doesn't look like a mad science project. It looks organic -- evolved, even -- like something born for speed. Huge, huge kudos should go to to Cervélo's engineers for their work, as it brings art and functional together perfectly.

The Ride

I can sum this up in a word: wow.

It's been a long time since I last owned an all-carbon bike. And I'm amazed at the combination of comfort and absolute, unyielding lateral stiffness of the bike. You turn the pedals, and she just goes. Road vibrations vanish into the frame and don't make it to the rest of your body.

At speed, the frame tracks straight and true -- let go of the bars and sit up, and you needn't worry about drifting off your line. Not that you'll be doing that in a tri, but that gives you a strong idea about the level of attention that went to the molding of the P2C's frame.

As a whole, the Ultegra group performs capably. As time has gone on, Ultegra has gotten closer and closer to Dura-Ace in overall feel and responsiveness. Weight, of course, remains the key differentiation between the two groups. However, that weight difference is negligible, and it's more cost effective to just lose a pound of fat off your body.

Some of the parts are fairly pedestrian, but for a sub-$3000 time trial bike, that's to be expected. My only points of contention -- the alloy stem (I would have selected a carbon model from FSA to improve ride comfort) and the choice to use a compact crankset -- were both put to rest on the first ride. This is not a bike for sprinting or criteriums. It's a bike for the long haul, and it manages both comfort and high-speed efficiency.

The wheels are what keeps the cost of the bike down -- the included Shimano R-500 wheelset will get you through your events if you're early in your racing hobby and can't swing the money for a pair of aero wheels. For me, they'll become a pair of "beater" wheels -- something to slap on the P2C or my road bike in the spring for training rides.

Slapping a pair of clincher Zipp 404 wheels on the bike (pictured above) makes an already awesome ride even better. Crosswinds were a little more noticeable, due to the height of the 404 rims. Overall, the ride quality was not impacted negatively by the switch -- it merely required a little more attention in a stiff crosswind.

Experience

A huge thanks has to go out to the staff that I worked with at Cervélo -- Brett, Ronald and Emma -- who were extremely patient, forthright, and quick to answer questions. I made a pest of myself, I'm sure, but I hope that they, and the rest of their team know how much I appreciate the level of customer service I received. And I'm just a shop mechanic who did an e.p. from them. I would be willing to bet that their customer support for Joe Average Customer would be as good, and possibly better.

Final Word

The best bang-for-the-buck in the time trial/triathlon space.

Pros: aerodynamics, ride comfort
Cons: compact crank may turn-off some riders
MSRP: $2500 (US).

Cervelo P2C

Cervelo P2C, Full View

The bike, she is finished. Well, mostly. I need to chop down the seatpost a bit so I can make it fit me properly. But other than that, yeah. It's done. And I am very pleased by this.

I will be following this post in the near future with a full review, as well as a HOWTO article on moving cables through a carbon frame.

Cervélo P2C (Ultegra)

Cervelo P2C (Ultegra Group)
I've often wondered why so many bike companies ship their time trial/triathlon bikes with such crappy wheels. I suppose that if I'd really thought about it, the answer would have been obvious -- low quality wheels are great for training purposes and help keep unit costs down. In addition, entry-level triathletes will get great performance out of this bike and all they need to do to make the bike more capable is to upgrade the wheels at a later date.

The P2C (Ultegra group) shown above might well be one of the best values in the TT/triathlon space.
