Cambo, Bonty's are made in 42cm and FSA's are 41cm c-c. Why you want 38cm? No stability out of pedals and mostly suited for pancake flat tt courses. Can u help us and explain why you prefer 38cm? This is way too narrow.

whooztheman,

Are the Bonty's 42 cm C-C or outside to outside? I am thinking of getting some, but wasn't sure how they measure their widths.

Bontrager measures c-c and FSA the same. At least this is what they write on their websites. A friend of mine bought the B and IT IS 42 c-c.

Just measured: correctly, it is 42cm center-center !!

Something rather special. I wanted the shifting cables to go through the s-bend extensions. Thus my mechanic had to make a whole in it!

Are your aerobar extentions (s-bends) within UCI limits for length? they look long.

I went with the Vision base bar and Carbon Pro extentions and am very happy so far. I do like the Bontrager setup as well with the exception of the arm rests being a little high.

Nice setup overall!!

I was keen for some 38cm c/c for aero purpose's only. it might save 2sec over 40km :D . just like lance used in the 19kmtt this year. i want them for flat courses.
plus if my girlfriend ever wanted a tt bike 40,42cm bars look silly cos it is such a small bike. her 40cm c-c deda road bars look silly.
i love this thread. TT bikes are definetly the gear freaks ultimate toy, so much more to play with and choose :D

Hi Casran,
Awesome pics and setup. Pls keep us updated if you find a way to lower your armrests. Is Bontrager stem in the last pic the final one, or is this pic from another bike? After you ride the bike a couple of times, please update us on whether you have a good, safe grip on fast downhills, plus, is the basebar stiff under 'pull' conditions during steep climbing? Thx and enjoy this bike!

Thanks Whooztheman. I am VERY tempted by a set now!

Casran, did you look at putting Profile F19 arm rests on? Do you think they'll fit?

Hey thx.

The carbon Bontrager stem (a Race XXX Lite OS Carbon) is the final one, very beefy, looks great (similar to the looks of a Zipp or Time Monolink stem). The other one was a Bianchi stem, only used during the setup of the bike.

I've been riding this bike only for 140km yet, but the ride is awesome. Very stiff and the titanium rides smooth. The handlebars are stiff so far, even on bad roads; they corner well. I haven't had the chance yet to do some downhills, since I live in a flat area; I'll do this probably next week.

I haven't done this yet. I picked up that idea on another website; a guy on this board told they made a mistake so it probably won't work. But so far I don't need to lower my armrests since I have a good aero position on the bike as it is: my back is totally flat if I'm riding in the extensions!

Casran, can we have a picture of you on the bike on a tt position?
Wanna see that flat back, plus the angle of your elbows. Just curiosity, nothing else :D
