Here's what others have to say...

Do I need any adaptors or washer kits to install the CX70 crankset onto my trek bike that has a BB90 bottom bracket?

Responded on

Hi there,

No, the BB90 system uses a 24mm spindle with an internal bearing. The frame has a wider stance than traditional bottom brackets but you do not require any ancillary adaptors or washers. Simply use a shimano bottom bracket (24mm) for your bike, and you are good to go.

Is this 10 speed and Sram shifter compatible?

Hey Bill,
This crankset is indeed intended for a 10 speed drive train. The comparability with SRAM shifters with ultimately be determined with what front & rear derailleur. But you would be able to use this crankset with a Sram drivetrain.

Please let us know if you have any other questions.
