i have omniums on my kilo tt, with a team sram bb. I'm installing the stock truvativ (dark Grey round) bb on a bt edge. The same crank arms from my kilo that fit, do not fit on the bt edge. The spindle is too long, I bottom out the spline on nds and the cranks can slide a good 5-10mm with a real audible slap. I know spacers aren't supposed to be used. My question is, why does the cranks fit on the kilo. With a 68mm bbshell and doesn't fit on btedge. (68mm bbshell) also, does anyone know what I can do? My neighbor had same issue with stock bb and cinelli mash. He used a 1.5mm spacer on nds. And because of the nds arm rubbing on bearing seat he blew the bearings to crap. (should i cut my losses nd get sram team bb)
