ok so here is the deal. i just got a pair of fabcraft wheels(8") with 25mm bearings and im planning on just cutting the spacers to fit the two and flip the track tensioners on the inside of the rails but my axle is machined on one side for two wheels and them the other side just one so should i get my axle machined down to fit the bearings or should i buy an offset axle and will i have enough slack in my track or will it be tight?? im looking into the avid offset axle if i have to get one. anyone know what side axle they have? thanks in advance!
