New Features
Compatibility
Split30 road bike cranks are compatible with a number of different drivetrain options. The cranks use a 30mm spindle which works with any 30mm inside diameter bottom bracket. They can mount to any bike with a standard 68mm BB shell with English or Italian threads. They are available as 110bcd 5-bolt pattern for chainring compatibility. The 110bcd cranks are not compatible with Campagnolo 110bcd chainrings, but any other 110bcd rings should work fine.
