Shimano Ultegra CS-6700 Bike Cassette

The Shimano Ultegra CS-6700 10‑speed cassette offers precise road shifting across five sprocket ranges (11‑23 to 12‑30). Constructed from steel sprockets, it pairs with HG 10‑speed chains and fits Shimano MTB freehubs, while remaining compatible with Shimano road 11‑ and 12‑speed groups using a 1.85 mm spacer.

The Shimano Ultegra CS-6700 cassette is designed for road cyclists seeking reliable 10‑speed performance. It provides five sprocket gradations—11‑23, 11‑25, 11‑28, 12‑25, and 12‑30—allowing a broad range of gearing options. Each sprocket is made from steel, delivering durability and consistent engagement. The cassette is compatible with Shimano MTB freehub bodies and works with the recommended HG 10‑speed chains such as CN‑6701. Additionally, it can be used with Shimano road 11‑ and 12‑speed groups when a 1.85 mm spacer is installed, extending its versatility across multiple drivetrain setups. The Ultegra 6700 series incorporates an optimized sprocket design that enhances shift precision, and it integrates seamlessly with a wide array of Shimano shift/brake levers and rear derailleurs listed in the specifications. This combination of material quality, gear range flexibility, and cross‑compatibility makes the CS-6700 a practical choice for road riders upgrading or maintaining their drivetrain.
