Mountain Bike Cassestte on Road Bike

[redrhodie]

I have a Shimano compact crank, and a 10 speed IRD 11-32 cassete, and it works perfectly. I happened to already have an Ultegra triple front derailleur, and that gave enough room that I didn't need a long cage rear derailleur. I remember when my lbs guy decided to try it out (without changing the rear derailleur), no one was sure it would work. That was over 2 years ago, and it's still working perfectly. No chain drop issues.

Redrhodie, I wondered if you could answer a question for me. When you are in your small chainring and your 32T does your rear derailleur bump up against your cassette?

Obviously, you are someone that understands "how" to shift your bike, because otherwise there would be some issues. At any rate, hopefully over time Shimano will come up with a 10 speed mountain group and that will solve most of the problems.

I've actually (consciously) never used that gear combo, but I'm sure there'd be some rub, and maybe even stress on the rear derailleur??? I use my 28T as my lowest gear. I do go through a lot of chains, so that may be an issue (like 3 this past year). Granted, one rusted, so it wasn't a stretch issue, but I have had chains stretch.

ETA:

I just checked, and it does indeed rub (the front derailleur/chain) when in the 32T. The rear derailleur seems fine, but I'm guessing the big ring/lowest 32T gear wouldn't be a happy place.
