WIGAN ?? Posted January 28, 2012 Report Share Posted January 28, 2012 the axle is probably too long for the crank so the bolt is just hitting the axle before its tightening, add a few spacers like ali said and it should sort it Quote Link to comment Share on other sites More sharing options...
Mark W Posted January 28, 2012 Report Share Posted January 28, 2012 the axle is probably too long for the crank so the bolt is just hitting the axle before its tightening, add a few spacers like ali said and it should sort it The length of the splined section shouldn't be long enough for that to happen. Equally, ISIS splines also have a slight taper so your cranks shouldn't really be able to move up that far. Equally, putting spacers on means you don't really tighten your cranks onto that spline so you're more likely to damage them more... Quote Link to comment Share on other sites More sharing options...
WIGAN ?? Posted January 28, 2012 Report Share Posted January 28, 2012 what am i even talking about haha this is what being out of trials and into bmx for ages does, if the splines are fine and they are brand new cranks then god knows Quote Link to comment Share on other sites More sharing options...
ooo Posted January 28, 2012 Report Share Posted January 28, 2012 longshot but... maybe you are missing the washer from the crank bolt, and the bolt has hit the end of thread without pushing against the crank, did you leave the washer in your other cranks ?
