I am a handy dude but i just can’t get it rolling smooth again and it’s driving me outta my mind!!
Do a double check on your truing proceedures and see if they Jive with this tutorial on the correct installation of the rear sprocket...Thats the best I got for ya on this.
Place washers and nuts on the bolts and tighten them so
the assembly is loosely held together with light pressure
on the spokes. All nuts need to have the same amount of
thread protruding.
Align sprocket and center hub so the gap is even all
round. Use a block of wood and a hammer against the
teeth to tap the sprocket into position, if necessary.
(Image right shows misaligned sprocket).
Tighten the nuts and bolts 2 full turns in a criss–cross or
star pattern and check the hub alignment again and
adjust if necessary Tighten the nuts and bolts another
full turn moving in a star fashion across the sprocket.
Repeat this process twice more, checking the alignment
as you go. The nuts should now be tight enough to hold
the sprocket firmly against the spokes but have some
flexing in the drive direction.
Spin the wheel and check that the sprocket runs true. Run out of more than 1.5mm may cause the chain to bind
and even jam or jump off the sprocket. Correct any side-to-side wobble by tightening the nuts where the
sprocket is further from the spokes to pull the sprocket back into alignment, and slacken the nuts on the
opposite side a fraction, if necessary. If there is a gap between the two rubbers, tighten all the nuts evenly,
until the rubbers are just touching. NOTE: Do not over tighten the nuts, the rubbers give some degree of
shock absorption, so If over-tight this will not happen. If there is still some run-out, use a large shifting
spanner to bend the section of sprocket giving trouble. You do not need to use much force to do this.
Place the wheel in the bike frame and install it as indicated in the bicycle instruction manual. At this time leave
the axle retaining nuts finger tight, they will be tightened later when the drive chain alignment is set. Check the
wheel and sprocket run true and adjust if necessary. Make any further adjustments as necessary.
