k11 1.0 bottom crank pulley bore size.

[owa rei]

Hi everyone, Im just looking into lightened crank pulleys for my brother and just wanted some info about the bottom pulley as we don't have a spare lying around that i can measure. So if anyone could just let me know what the internal bore is on a cg10de crank pulley it would be much appreciated.

Cheers, Richard.

Hi frank, your close! could you just measure the bore of the centre hole with the notch out of it, it looks about 2.5 cm but just would like to be sure, i hope you know which bit a mean Im not very good at explaining these things.

Cheers, Richard.
