Can someone point me to a product to fix my frustration. I'm putting my new bike together and just realized that my ultegra crank is a 165. Returning it is not an option. I'm 6'02 so the 165 won't work. Is there a way to replace just the arms or do I have to buy an entire crankset? Either I am way too frustrated to find the part or I am missing something. Either way, some guidance would be great. If it helps I need a 175.
