Z100 bb
 

I recently came into a used Felt Z100. The previous owner did multiple centuries and 70.3s on it. The bottom bracket has started click/popping on me and it's time to swap it out. Problem is, I can't find what size BB to use, and I've had no answer back from Felt.

Suggestions?

Take off what you've got, it should be marked/measure it/take it to a bike shop. You will have to remove it anyway.

A Google search indicated the Z100 uses a Shimano Claris crank that requires a 113 mm Octalink V2 bottom bracket.
