Klein Q Carbon Race enroute what size f Derailure?

[Raymond_mole]

Hi
I have just bagged a sweet frameset on line and have a groupset here awaiting its arival.
problem is my braze on front mech wont fit and would love to have one here ready to build.

Any ideas what diameter front mech fits the above frame?

Cheers for your help with this matter in advance

Sorry can't help with the dimension as mine are earlier and different. Frame looks nice good luck with the build.

FWIW there are only three standard sizes of clamp-on front mech: 28.6, 31.8 and 34.8 and are typically indicated by material / seatpost size. The first is steel, the second is typically a 27.2 post and alloy/ti or carbon and finally 34.8 frames typically take a 31.6 post.

Same diameter as my Reve and the older Aura (which is actually the same frame as the Q Carbon). 34.9 mm.
