Title: power disc help
Post by: bmx xxx on October 30, 2007, 06:49 PM

right i might be being a rit nood, but want to fit a power disc set up, to my redline crank arms , the redline chain ring has a little extra hole where the crank arm fits nicely instide the chainring, but on the power disc it sits outside the hole, trying to explain, or do i need a different power disc, cheers

You're going to have to fit a spacer of the right size in between the face of the power disc and the rear of the drive arm boss.  :daumenhoch:  G.
