Cervelo S2/S3

[Six13]

110BCD mid-compact ie 52/36.

I put it on a diet - here's the parts as supplied so plenty of fat to trim:

front wheel 829g
rear wheel 1153g
skewers 150g
tubes 178g
tyres 478g
stem 152g
saddle 306g
bars 323g
shifters 486g
FD 89g
RD 234g
calipers 360g
crankset 770g
==================
total 5508g

On the basis that an improvement is OK if the amount saved in g is less than the cost in $, I used my own deep dish wheels, replaced the stem, saddle, bars, calipers and shift kit (SRAM Red / Force), and in doing so I got the day to day weight down to 7765g (eg this config uses puncture resistant but heavy commuting tyres), a race weight of 7416g (titanium skewers, light weight tyres and tubes), and a climbers special of 7236g (my lightest wheels).

HTH!

That's fantastic info thank you.

How do you find the bike in the hills?

Goes OK, certainly I use less power per kph than on my other bike, a CAAD9 DuraAce.
