The Shimano SLX CS-M7100 12-speed cassette is characterised by its Hyperglide+ technology, which ensures high precision and smoothness as well as shifting speed when shifting up or down. In addition, Hyperglide+ minimises noise.
CS-M7100 cassettes feature an aluminium spider and sprocket (the largest sprocket), which saves weight and contributes to durability. If the lowest possible gear jumps are important to you, then go for the 10-45 version. If you want to cover as wide a range as possible, the 10-51 gradation is the right one for you.
