Are you moving from a 3 ring crank two ring crank?

If yes...Have you got a new bottom bracket for the two ring crankset?

If no...your two ring crank set will be too far from the frame and will impact your shifting and what cogs you can get to if you use the bb that came with the 3 ring crank.

so if you have to get that crank plus a new bb then cost wise the crank I gave you above sould be on the table.
