Chorus 10 speed Rear Derailleur - max teeth

I've run a 13-29 with a short cage chorus 10sp mech. Absolutely no problems on my bike with standard chain rings up front. So, I'd think that, unless you have mega long chain stays, you shouldn't have any probs.

And, as you're getting the casette anyway, you may as we'll try it before splashing out on a new mech too!

Thanks for the feedback!

Were you ever using the large ring in the front with 29T in the back??
If my chain is optimised for my current setup (was installed by my LBS) should I be buying a new chain as well?
Would you by any chance have the cassette available to sell :)
