Description
The Shimano FC-3550 Sora 9-Speed Compact Chainset is designed for easier installation, adjustment and maintenance. The 2-piece design allows the bottom bracket bearings to be spaced wider apart (outboard the frame) enabling the use of larger bearings and an increased axle diameter. The double-ring 9-speed chainset is excellent value, featuring strategically placed chain pick-up pins and tooth profiles to ensure fast and positive shifting.
