It's for the commuter/tourer thing..
Taking it to Guernsey this weekend, and will be lugging Jnr in the trailer, and panniers full of GHDs and 'stuff'...
Want to drop from a 42t on the front, to say, a 39t.
Is this any good?? I can't see ramps on the pic, but google suggests it's part of a 53/39 set up.
Ideally need it before this weekend, so suggestions appreciated!
