The Shimano Ultegra CS-6700 10-Speed Bicycle Cassette is crafted with a rigid alloy sprocket carrier for a more lightweight, durable profile that enables smooth, more efficient gear shifting.
This innovative upgrade on Shimano’s classic 660 and SL versions features reduced weight, ni-plated Hyperglide sprockets with improved teeth shaping and revised ramps for smoother, quicker and more accurate shifting.
The Ultegra CN-6701 10 speed bicycle chain is a narrow, lightweight directional chain engineered to offer optimal cassette and chainset interaction and maximum power transfer for a greater cycling performance.
The outer plate has been developed to reduce the chance of chain suck while the inner plate is designed to give better, more efficient contact with gears for smoother shifting under high loads, enhanced rigidity and almost silent operation. – L.R.
