Description
Shimano 105 Di2 CS-R7100
The 105 12-speed cassette delivers smooth, precise shifting for Shimano 105 Di2 drivetrains. And with a wide gear range it’s ideal for tackling varied terrain.
It works with 11-speed Shimano freehub bodies too. It makes upgrading to 12-speed easier; there’s no need for a new rear wheel or freehub.
Steel sprockets are attached to two aluminium spider carriers.
This balances durability with weight savings. The gear steps are carefully optimised for consistent cadence and efficient power transfer.
The 12-speed configuration offers closer gear ratios where you need them. The wider range is ideal for climbing steep gradients or pushing hard on the flats.
12-speed gearing for smoother cadence transitions and improved efficiency.
- Standard HG freehub compatible, no need for Micro Spline or new wheels.
- Steel cogs with aluminium spiders for strength and reduced weight.
- Optimised for Shimano 105 Di2 R7100 series, but compatible with other Shimano 12-speed road drivetrains.
- Close gear progression at the high end helps maintain rhythm, while wider ratios on the low end offer climbing confidence.
