i was thinking of getting kooka’s for my 20" willl they be to big?

about the biggest you can get on a 20" is 140mm, and the kookas are 170 or 175 I think. So yes, the kookas will be too big. And don’t get the montys, as those have taper problems and will never tighten correctly (I’m talking about the 140s, not the 158s)

HOpe this helps, Later.

I have a set of Kooka’s machined down to 127’s (Darren Bedford) and they are AWESOME
