Size 56 (suitable for height between 175cm and 188cm).
Bought in 2013 and hardly ridden since, hence is in super shape. Selling as I do not do tri these days.
Here are factory specs:
and BikeRadar review:
From the original, the bike is updated with fancy tri water cages (profile design and xlab, ideal condition), Selle Italia saddle and Token areo wheels (review). Paid $6000 (wheels and upgrades)
Comes with Look pedals (+ felt factory wheels from initial setup)
Serviced regularly in Trekonlogy bikes (chain and internal cables replaced).
