I've got a couple of queries....
Crank length. Do you folks buy into the arm length being proportional to leg length argument? I've got 172s at the mo which came stock with my Bianchi Sempre. I've had them for a few years. Riding around Sydney for a couple of hours is fine but doing some of the sportives such as Alpine classic and 3 peaks etc and I'll get back cramps half an hour into a climb. I've had a fit so my position should be fine. I'm 174cm (5'8") with a 79cm inseam comprised of short femurs - I'm more torso than leg. Basically, I've got a bit of room to play with in airline economy seating. I'm thinking that my pedal circle is too big for my proportions leading inefficient pedalling at the 10-2 of the pedal circle, and greatly reduced hip angle on climbs or when I'm in the drops. I need new cranks as my FSAs are rubbish, and I'm considering changing to 167s. Anyone else had experience with decreasing crank length?
It leads me to my second q. I'm running Campy veloce 10s and want to buy a force or red crank because they are one of the few models that come in BB30. Apparently, they require SRAMs yaw front mech to work properly. Does anyone know whether these 11sp rings/mech will be compatible with campy 10s shifters? I'm also considering upgrading to 11s at some stage which is why I'm getting an 11s crank, but this upgrade will also be Campag - prolly Athena.
Cheers.
