This is my last set of my personal Ti RS4's (I sold four this week). I upgraded all my bikes to the new RS4X model. The system has been lightly used, and retails for $868.00. Some wear on the Rotor logo on the drive side crank. Yours for $395.00 + shipping.

Race X-Terra or XC MTB? This sytem will help you go faster, improve traction, and improve climbing ability.

Brand new unused chainrings.
