Experience a more precise and smooth ride with a cassette from Shimano

Discover Shimano's latest innovation with the R7101 105 cassette, offering 12 speeds for a more precise and smooth cycling experience. This cassette is part of the 105 series, positioned just below the renowned Dura Ace and Ultegra series. With the introduction of Shimano's new Spline system, you achieve an improved contact surface between the cassette and the cassette hub, resulting in superior power transfer.

This model is compatible with both the new Spline system and traditional 11-speed HG cassette hubs, making it versatile and accessible for many cyclists. With the 12-speed cassette, you benefit from smaller jumps between gears, especially in the so-called "sweet spot gears," optimized for smoother and more comfortable shifting. The tooth profile is also updated to ensure more consistent shifting, even under high load.

• Improved power transfer: Thanks to the new Spline system.
• Greater compatibility: Works with both new Spline and traditional 11-speed HG cassette hubs.
• Optimized shifting: Smaller jumps between gears and an improved tooth profile.
