Help cranks move when i pedal

send an email to gp, he is likely to reply very quickly with some help.
also try look for tips on KH cranks as the GP crankset is the same.
Have you greased the splines etc?

how much is it shifting? just millimeters? micrometers?
most cranks will have a little bit of movement when they are new and
settle, splines should br greased tho

it wont be the spokes. just take off the cranks and check to see if the
bearings slip on the hub. As roger from UDC told me at BUC "it's never
the spokes"

It is a splined hub isn't it?

yeas it is splined, the same as a 1st gen KH... anyways, sometimes it is
the spokes :P still i agree, it is less likely to be the spokes and so
far he hasn't done anything so need to start with cranks then hub etc
etc

well with splined the margin between grip of the bearings and the hug
has no tolerances. was the same with both my new KH20T and KH24F this
weekend, you have to take off the cranks see if the bearings free move
off the hub. If they do then you need to put a strip of printer paper 1
layer think around the hub and put the spacer and then the bearings
need hamming back on top over that.

You'll need a off cut from a seat post, rubber hammer and a flat head
screw driver to do it.

Put the paper around and then use the screw driver to widen the spaced
to put it down over the paper to the very end, and then you hammer the
bearing on straight as far as it goes. The bearing will not move then
as it shouldn't, just make sure your hitting it st8.

Only other thing it can be is the bear cups on the bottom of the frame
you ain't putting on tight enough. Perfect test I found is to spin the
wheel, it should free move and slow down a little more then a pedal
bike would, but not slow down to fast to a stop. Just make sure you
tighten both bolts evenly. If you tighten them when doing it a little 2
hard wont do a damage unless you ride it, just let them off 🙂

All my teething probs with my uni's are now sorted 😄
