Chorus 10 speed Rear Derailleur - max teeth

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 :)

It'll run big cog to big sprocket just as well as with the 11-25 block (just try not to do that 'cos the chain is better running as straight as possible).

Try it with your current chain first - it might be fine.

Not for sale, sorry.
