Coach Jared Builds A Bike

Finally, after 3 months of waiting, my new weapon for 2010 showed up.

It is the new super-fast, ultra-sleek Cervelo P4. I am so excited to finally get on this beast after racing on a P2 (2008), a P3 (2009) and now the big gun for 2010.
One thing I find incredibly interesting when it comes to bikes is the process of building and fitting it.

1) The geometry of the bike is exactly the same as the P3, so I duplicated my saddle and front end. My saddle height remains 76.2cm with a virtual seat tube angle of 79.5 degrees. I use a 100mm stem with a -8 degree angle and 3cm of spacers under. This gives me an 11cm drop from my seat to my pads.

2) The Build is something I have always had a lot of fun with.

a) I am a firm believer in the Bontrager XXX Lite Aerobars with the S-Bend Team extensions. They have a ton of adjustability and fit me absolutely perfectly. Also, they weigh a mere 630 grams, which makes them as light as some of the best bars of the market!

b) I have found that for me, the Fizik Arione Tri 2 (the most popular tri saddle on the market) just doesn't fit me well. I ride way up up on the nose and have found the Specialized Tri-Tip with the 50mm nose, fits me best. That was one of the few things I kept from my P3, just because I like it so much. It adds a bit of weight, but it is so comfortable, it is well worth it.

c) For this specific bike, I am trying something new when it comes to the cable housing and chain. The P4 has some real extreme bends for the cables. Therefore, I am running Nokon Cable housing for their aluminum links that make the housing bend really well. It also is known for preventing cable stretch. For the chain, the KMC X10SL is about 50 grams lighter than traditional 10 seed chains

d) Hydration on the Cervelo tri bikes is always an issue. The P4 has an integrated waterbottle above the bottom bracket this is a real long reach. The only benefit of it is the aerodynamics it adds. Therefore I have always run the XLab Sonic Wing with a pair of Specialized Rib Cage Pro cages. This is the best way I have found to hold bottles behind the saddle without launching them. This year, I will be running a different front end hydration system. In the past, I have used the Profile Design Aerodrink set up. This year, I will be using the X-Lab Torpedo Mount, which holds a standard waterbottle on the aerobars. Should be pretty cool and very versatile

c) Other parts of the bike that will be used. It comes stock as a Sram Red bike...which is killer. The few adjustments I made is to use a 54-tooth TT chainring as well as the killer Sram R2C Shifters (they always face one direction, hence Return 2 Center).

d) I will continue to use Shimano Dura Ace Pedals...because they are GREAT! As for wheels, I will use the stock Easton Wheelset that comes with the bike, then as race season nears, I will decide on what type of aero wheels will be appropriate.

Right now, the bike is in a box waiting for a few parts to show up. I hope to have it built within the next 2 weeks and I will post pictures, weight and all the various info about it.

See you at the races (with my bike)!

Cheers,

Coach Jared
