I am trying to locate a company that makes a longer spindle for the bmx type bottom bracket. The spindle is too short to work in a 100mm shell and Deity doese not make one. I tried a profile. the length will work, but the diameter is not a true 19mm it is actually 3/4". and the bearings and the crank arms wont fit. any one make a 7" 48 tooth 19mm spinle? I could use some help on this one!!
