I have worn out the stock FSA crankset my CAADX came with.

It has Tiagra shifters so I thought I'd stick with it and buy Tiagra crankset but there are 4 options online in the compact I want from 165mm -175mm and I can't work out what this measurement is.

I have BB30 if that makes any difference.

Thank you in advance.

Crank length.

How do you wear out cranks, by the way?

Crank arm length.

How tall are you, and how long is your inside leg?

You can't get BB30 Shimano cranksets, so you'll need an adapter too.

Assuming it's your rings that are worn out I'd probably stick with the FSAs and just stick new rings on.

OK thanks very much for all replies. Didn't know that id need an adapter to put a Shimano crank on a BB30 either.

Yep it's the rings that are worn out so I'll replace those for now. Just thought that Shimano crankset looked quite neat.

Usually the crank arm length is etched on the back of the cranks near the hole which the pedals go in. If that makes sense...
