Crank Advice

Road cranks are designed to sit further out from the BB shell, to accomodate the inner chainring/s.

You would need a smaller spindle than the Track Dura Ace cranks use.

Sheldon has a large database of chainlines with different cranks. I would work out which BB spindle length will give the road DA cranks a chainline of 42mm (most likely what your will be).

also, the dura ace road cranks are hollow. they are no good for fixed gear, especially if u plan to ride on the street. they WILL snap or crack at some point. It's also very difficult to get a straight chainline with the octalink bb type crank arms. the bb's dont come in many sizes, there is a fixed version of the dura ace bb but its about £60 i think. basically dont get thre road cranks!

You're much better off with the old type Dura ace square taper track cranks, which will give you a wide choice of BB's, plus depending on your choice you could always change to Sugino or Campag even.

great, exactly the kind of info i was looking for. thought the road cranks would need a different spindle but wasn't aware of the issue with the hollow cranks. thanks for all your help.

gotta work out whether to throw 150 on the square taper DA track chainset or opt for the less expensive miche/dia compe ones.
