• Does anyone already experienced to ride fixed with a Campagnolo Ultra-Torque crank ?

    Yes, many years, two sets of Veloce and two sets of Mirage, and I'm in the process of bringing a Fulcrum Racing Torq RS into the fixed stable. The hidden fifth bolt means you have to modify either the crank or the chainring if it is thicker than the stock one, and you need some shims if it is thinner. My blog is dead due to php version changes, so here are the pix.

  • thanks, my plan is to modify a bit the right crank arm, but I'm more worry about the chain line than the chainring compatibility.

    Any chain line issue ? In the thread mentioned by @umop3pisdn someone said that the chainline goes to 46mm.. Is that right ?

    Usually track crank chainline is around 42.5mm, maybe a simple spacer between the hub thread and the freewheel could do the trick ?

    I think it's more like 47, depends a bit on which chainring you use

    You're unlikely to fit that much packing behind a sprocket and still have enough thread engagement. Since all my fixie bieks use road cranks, I just rebuild my hubs to suit with customised axle parts.
