What Is It?
The Shimano CS-R7101 105 11-34T 12-Speed Cassette is a high-performance 12-speed road cassette developed for the Shimano 105 R7100 mechanical and Di2 groupsets. Incorporating Hyperglide (HG) shifting technology, it delivers fast, precise, and reliable gear changes while maintaining smooth pedalling under load.
The 11-34T gear range offers a versatile combination of closely spaced gears for efficient cadence on flat terrain and lower climbing gears for tackling steep gradients. Built with nickel-plated steel sprockets mounted to a lightweight anodised aluminium spider, the cassette provides an excellent balance of durability, stiffness, and value. It is compatible with Shimano's HG L2 12-speed road freehub standard.
