This year at the tour Or 2011 vuelta on the Angliru? :mrgreen:

The 42 inner is the same over the whole rotation as a 42 round, and "feels" very comparable. probably nearer 46 at the max and 38-39 at the deadspot. Moving to a slightly bigger cassette will minimise any difference you feel up hill.

However the ovalness does help keep fluidity and momentum climbing better than a round ring IMHO.

So a 42T O.symmetric inner will feel comparable to a standard 42T inner? With Campags biggest 29T rear choice that will effectively give gearing equal to 39/27, which I for one find a tad on the heavy side for long sustained climbs of around 10%. Not that I climb those all the time, but being able to choose suitable gearing for those events is something I'd like to do. Hmm.

Yeh the osymetric 42 gives the same roll out as a round one. They do a 38-52 in 110bcd if thats any help.
