SHIMANO ULTEGRA CRANK ARMS FC-6500 172.5 LENGTH FSA 46/38 RINGS Compact
GOOD SHAPE
These are a popular crank in production between 1997 and 2004. All major bike brands would have spec'd these. It would have had 42/52 chainrings originally. It was designed for 9 speed derailleurs but with the upgraded FSA rings it can work with 9 or 10 speed. You will need a shimano octalink bottom bracket and the size depends on your frame.
