|Need component advice for TT bike||Duane Gran|
Apr 20, 2001 7:46 AM
|I'm officially off the deep end now. I'm planning to build up a time trial bike. For whatever reason, I have an interest in this sort of thing in addition to road biking. A friend is selling his Trek 2500 bladed frame and I need to select some key components: |
* fork (wanting carbon + carbon steerer)
* group (Shimano, see below)
* bars (wanting to go aerobar)
* wheels (have a plan already, see below)
* seatpost (want something bladed & aero)
I may be migrating some Ultegra components from my road bike and upgrading to Dura Ace, but I'm not sure. I have some Zipp 303 wheels on order, so I will probably invest in a Zipp disc wheel for the rear and use the 303 in front. A 404 would be a little more aerodynamic, but I think it a small compromise.
I'm willing to spend decent money to do this right, but naturally I don't want to go crazy. I have a rough limit of about $2000 in mind, so I might be purchasing some parts used once I know what I want. I have left out some parts, like pedals and seat because these are already settled in my mind. I'm just a little fuzzy on the parts above, particulary the fork, bars and seatpost.
Suggestions on components are most welcome. If some more info would help, please let me know and I'll expand on this.

|I'm debating building up a dedicated TT bike right now also as I'm in the midst of a weekly TT series where I'm actually competitive.
From talking to other racers on dedicated TT rigs, the biggest advantage would be aerobars with bar end shifters. This allows you to shift more often and stay in position, particularly beneficial when the course isn't really flat or it's windy. In TT bikes, lightweight is secondary to aerodynamics. Most of the true aerobars like VisionTech, Cinelli Angel are only available in 1" threadless, so carbon steerers are out. These bars are pretty heavy and expensive, but they're used on all the top TT bikes. Less expensive option would be a regular road stem with something like a Syntace Cowhorn bar and aero clip-ons. Get DA bar end shifters and Dia Compe reverse brake levers.
For wheels, obviously a disk and tall section front would be ideal. That's A LOT of money.
FWIW, a better deal may be to get a Cervelo P2K built up with aerobars and Ultegra for just under $2K ($1195 frame/fork). That's what I'm looking at. Excel Sports has them, and most of the parts mentioned above.

|You bring up an interesting point. A full Cervelo bike with Ultegra would be $2100, which isn't too far from what I had planned to spend. Even though I can get my friend's frame for $150, I was expecting to have to spend: |
* fork ~300
* bars ~250
* group ~1000 (dura ace)
* seatpost ~100
That would be 1650+150 before I have purchased a disc wheel. Of course, I won't have to purchase a full group, but I'll need 90% of a group, so the price is probably right on. The Cervelo looks pretty slick. Can any TT buffs out there comment on these bikes?

|I started road racing last year, but have been doing triathlons for a couple of years now. I ride a Cannondale road bike, but just purchased a Cervelo p2k last summer, and love it. Just by switching from the cannondale (caad 4 with ultegra/forward seatpost/aerobars) to the cervelo, i dropped my 40k triathlon bike time from about 1:01 to 57:00, so I am clearly in support of the cervelo. I can't comment on the harshness for you, but have done an ironman on it, and was fine, but I weigh about 170 and ride a cannondale as my training bike. I actually did the same component upgrade that you are talking about. I got the cervelo in 700c with ultegra minus the wheels (just used my wheels that i already had), and it cost about $1800. I then upgraded the components on the cervelo to D/A, and changed from syntace bullhorns/clipons to a Profile Carbon X, which I got for $150 with shifters/brake levers from the classifieds on this site, so it was essentially a free upgrade, as I sold the syntace setup for $160. The Carbon-x is awesome, and takes out a little road shock from the aluminum frame. this year, and transferred the ultegra to the cannondale, which had 105. I then also bought a disc, and am about to purchase a custom set of zipps from american classic, who I'm sponsored by for collegiate racing. I would strongly recommend the cervelo, it is a fabulous bike, and extremely aerodynamic. If you are very interested, check out www.slowtwitch.com,they have a good review of the cervelo and other tri-bikes (TT same thing). Also, they have a list of shops to recommend. I would not recommend excel sports; although they are an excellent bike shop, they are probably not the best source for tt specialty equipment. Check out www.nytro.com, www.insideoutsports.com, www.missionbaymultisport.com, or www.endurosport.com I got mine from endurosport which is in Canada (although i am in Ohio), as they were the only place that had my size in stock at the time. All of the stores are extremely reputable though for tt equipment, and can answer any questions that you might have far better than I can. Email me if you have any questions|

|I just plunged for a Cervelo P2K. It's spec'd out w/ Ultegra stuff, a CK headset, Syntace Cowhorns and Ultralight aerobar, and Speedplay X2's. It was built by Excelsports. I threw on a HED3 front and a HED Deep rear, and it's ready to go. Since I live in CO, I went up to the store in Boulder and worked with one of the guys up there to spec it out. Very professional guys by the way, and nice to work with. A few weeks later (I had to wait for the 2001 model) it arrived, and it is suh-weet!!
I can't ride it as fast as I would like, but that has nothing to do with the bike. It felt pretty solid, and not un-comfy at all last week at the CCTT (which, for all you non-Coloradans, is a pretty rough course). I haven't given it any extended distance testing yet.
Anyhow, it is REALLY pretty to look at and it feels really fast. Once I get in decent shape, I'm sure it will be. :-) Good luck Wednesday.

|Yep, the P2K is a pretty good deal especially for a dedicated TT/Tri bike. I too waited for a 2001 model (my dealer had just returned from Interbike 2000 when I first started researching the P2K and was excited about this bike).
I spec'd mine with Ultegra brakes, Syntace Space Control levers and a 3T Forgie stem... along with a Profile Carbon Stryke aerobar and Syntace 15 degree Stratos. For full tilt boogie race days... HED Stinger 90 tubular rims (Conti Competition rubber) and an alternate HED SuperLite disc.
Ironically, I found an old GT Vengeance frame at a LBS a few weeks ago... and after a paint job, it'll be built up similar to the P2K except having 650C ZIPP 404 clincher wheels, a ZIPP 840 disc and a Reynolds Ouzo Pro Aero fork (this puppy is light for any fork let alone an aero one). The Vengeance has a shorter headtube (1 cm). The Vengeance frame does not conform to the new UCI regs for aero frames... but I don't race UCI!!! It will be interesting to compare and contrast what are arguably two of the most aerodynamic double diamond frames produced.
The P2K was supposed to replace a converted road bike (I still use this bike) and in retrospect, was only slightly more expensive than the original conversion.
Here's a pic of my P2K... Will post the Vengeance when it's done.
Be the bike.

|Many thanks to everyone for their input. Akirasho, that is one sweet looking ride. Thanks for posting it. |
As I compare the costs, it really does look more affordable to go with a P2K. I probably won't rush right into it, but if the finances smile on me in the coming months I'll see. Again, I appreciate the feedback from you all.
