i agree for the SL's to have 0 offset is a bit shit considering they're single wall aswell, ive got a viz one on at the moment which has a massive spoke offset and had been pretty good so far, to be fair though i do weigh over 15 stone so it was inevitable for it to die i just never expected it to go as quick as it did and the choice of strong rims on the market these days is scarce so i had to get the trialtech
dunno what everyones on about i thought that was ace ! clean flowing lines but still keeping it trialsy it was bang on, only criticism i would have is the music didn't go well with the feel of the riding
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
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
everyone's overlooking the fact it could be your cranks, if your chain is moving when you're turning the cranks its a problem with the hub, if not its the cranks
