Shimano Dura Ace crankset FC-7700, 172.5mm, with chainrings 53/39t

(Shimano's lettering on their 7700 series was very superficial/easily rubbed off). Dura Ace 7700 was a 9-speed system (9 X 2). It should work fine up to 10 speed. Weights: right crank with chainrings 53/39: 401 g; left crank 199 g; total 600 g (weighed).

Thank you for your interest in this quality crankset with a history of moderate use. The chain rings show normal wear. There are minor surface marks and scratches. The spindle interface and pedal threads are in good shape. The original matching bottom bracket is in smooth operating condition.

Made of aluminum and steel, the technology of this Octalink V2 system was overcomplicatingly simple. The set includes one bottom bracket and is specifically designed for a 109.5mm shell width. This bottom bracket was taken directly off of a 2005 Cannondale r3000si and includes everything that is shown in the detailed photos.
