Shimano’s Ultegra 6600 crankset shares its lineage with the legendary Dura Ace crankset and is designed for cyclists that are looking for a high performance crankset that won’t wipe out their savings. Featuring Hollowtech II technology, the Ultegra 6600 crankset uses outboard bearings that create a stiffer bottom bracket/crank interface and distribute load more evenly than square taper setups. SG-X technology on the outer chain ring uses teeth with special tooth profiles to ensure consistent and smooth shifting, even under load.
- Fits 68/73mm bottom bracket shells
- External bottom bracket included
- Hollowtech II technology
- SG-X outer chainring for smooth, consistent shifting
- Integrated crank spindle
- Weight: 854g, including bottom bracket
