Shimano Ultegra CS-HG800 Cassette

The Shimano Ultegra CS-HG800 cassette is the ultimate choice for cyclists who want to combine Ultegra performance with a wide range, ideal for both road bikes and gravel bikes. This 11-speed cassette is specifically designed to fit a standard HG-11 freehub body of both road and mountain bike hubs (with a 1.85 mm spacer for road bike hubs). This ensures maximum flexibility in wheel choice. The advanced Hyperglide technology guarantees smooth and precise shifting under all conditions.

The construction of the CS-HG800 is focused on an optimal balance between lightweight and stiffness. The largest sprockets are mounted on an aluminum spider (carrier), and the largest sprocket itself is made of aluminum, while the remaining sprockets are made of durable steel. This design minimizes weight on the outer part of the wheel and maximizes stiffness for efficient power transfer, contributing to better climbing performance.

The most popular gearing for this Ultegra cassette is the 11-34T (11-34T), which offers a wide range for steep climbs without making the step size between gears too large for quick cadence changes. This makes the CS-HG800 perfect for gran fondos or adventurous gravel bike rides. For the best lifespan and shifting performance, it is recommended to combine the cassette with a Shimano 11-speed chain such as the CN-HG701.
