Default Re: Help! Dax shift kit, SBP BB adapter, crank has play!

There are two widths of BB tubes. One requires a 68 mm bearing spacing and the other requires a 73 mm bearing spacing. Never seen a one piece with the 73 mm but there is a first for everything. What you are looking for is a 7R spindle. 134 mm wide with 73 mm bearing spacing.
Design is easy, execution the hard part.
