Compact road crank

RJ Peterson said:

I just bought a compact crank and am wondering if it will work with standard
(short cage) road rear and front derailleurs and 13-26 or 13-23 9 spd
cassettes? The crank has 50/34 teeth -- it will replace a 50/39 setup.

Thanks

yessir-lower the front der, parhaps take one link out of the
chain(depends if the chain was correct length to start with), go ride.

Are you replacing a 50/39 or a 53/39?

Look up the specs on the existing derailleurs. They should state the
total numbe of teeth each can accomodate.

Which crank did you buy? I put a campy record compact crank on my scott
cr1 and had to put on a new front derailleur as well.

Yes, assuming the front derailleur, if a braze on, can be lowered
enough to the 50.

Lessee, 26-13 = 13. 50-34 = 16. 16+13 = 29. According to Campag.,
anyway, that should require a medium cage rear derailleur. The 13-23
cassette fits the spec range for short cage.

There is no reason to *not* use the medium cage.

That's fine and dandy, these numbers, but they are wildly conservative
in most cases. To look at a number and 'decide' it won't work is a poor
idea, IMO. I try lots of combos that should not 'work', but they
actually do. Like a 12-32 8s cogset on a DA 8s setup once.
