Shimano Ultegra Crank Arms

A friend gave these to me the other day. The chain rings were thrashed but it looks like the arms are fine. They will make great SS crank arms.

Specs:
170 mm crank arm length
110 mm BCD

As for chain ring size, I'm looking for 46t.



I added an old FSA chainring I had laying around. They look really good and the ring is 46T. Lucky for me!



I picked these chainring bolts up at Incycle. These are needed for a clean SS crank conversion. Without these the original bolts won't fit right when you remove the second chainring and finding washers to fill the space is a pain in the a$$.

    Everything was free and from my collection of parts. The only thing I bought were the bolts.
