Rotorcranks Ti RS4 172.5 55/44

I’ve finally given up on trying to install them. In fact I never tried… I recently bought a nice new FSA 54T aero chainring, and I don’t think I’ll swap it out for rotorcranks.

Also priced to sell (like zipps’ ad… please consider his rotorcranks first…(= ) at $250 shipped. They aren’t new… I bought them off another slowtwitcher some time back…
