Shimano Ultegra CS-6700 10-Speed Cassette

Shimano decided to re-design their Ultegra groupset to the new 6700 level with trickle-down technology from the new Dura-Ace 7900 group. The CS-6700 cassette has thus also added some features over the previous 6600 cassette. Most striking is the addition of an 11-28 spread which has proved incredibly popular in the Dura-Ace and SRAM road groups. They also machined holes in the larger cogs to reduce weight and the last three cogs are held together with a lightweight alloy carrier. Lastly, they further refined the cog tooth profiles for crisper shifting especially under load. Compatible with Shimano and SRAM 10-speed systems. Weight: 236 grams (12/25).
