It originally started life as a 2010 58cm Tarmac Elite with mostly Shimano 105 components. It was originally 19.5 lbs or 8,853g with Crank Bros. single Ti eggbeaters.
The bike has evolved extensively over the last 12 months and now the only items remaining from the original build are the cable housings, modified bar eng plugs and bar tape. The 2011 SL-2 frame is the workhorse Tarmac frame with the lower end 8R carbon. It's not the pro spec lightweight SL-2 from 2009 so it's pretty heavy for a carbon frame.
This is how it stands today: Any missing weights are simply because I forgot to weight before install or I can't recall the figures.

She's pretty close to being done but I'm planning for:
- a set of lightweight cables and housings
- a lightweight carbon headset top cap and aluminum bolt
- cutting a little length off the handlebar drops.
- Specialized Toupe Pro carbon railed saddle
