We do carry a Powerspline bottom bracket for a 68mm shell with a 108mm spindle and is available in the drop-down size menu.

You will need to make sure that your crank needs a PowerSpline bottom bracket and not a square taper or ISIS splined bottom bracket.

You would need to use a PF30 or BB30 to English thread adaptor to use the TruVativ PowerSpline bottom bracket in a PF30 or BB30 frame.

mlewis · Answer

Yes, any Truvativ Powerspline crankset is compatible with this BB.

canteau · Answer

Power spline is designed to be an entry level, low cost standard.

You will have to upgrade the entire crankset, which is going to make the entire bike lighter and shifter better.

canteau · Answer

The 68mm and 73mm versions of the bottom bracket are English threaded, the 70mm versions are Italian threaded.

The E stands for E-Type, which is a type of front derailleur mount that attaches to the bottom bracket.

bhardy · Answer

Yes there is. Look up the manufacturer's specs of the crank you have. They will list the spindle length. You can also take calipers and measure from end to end on the Bottom Bracket Axle. Without the crank arms or bolts on the bike.

smulder · Answer

You can take a ruler or caliper and measure across your bottom bracket shel on the bike that will either be 68mm or 73mm. You don't need the 'E' Version unless you have an E-Type front derailleur that mounts to the Bottom bracket.
