OK, after experimenting with chainrings I’ve found I prefer the feel of the O.Symetrics.
But I can’t run a 38 on the Haute Route, it’ll be suicide of the knees. I’ve got a 27, but even then I fear that’ll be too big.
Arise the 29! Campagnolo do a 12-29 that works with a standard mech, and is supported by EPS too. Result! This is more or less the same ratio as a 34 x 27, so that’ll do nicely.
OK, really ready now.
