Pros & Cons

Pros & Cons

  • This cassette has a wide range by the addition of a '10' as smallest tooth.
  • This cassette also allows you to shift gears smoothly and quickly in rough conditions and when there is a lot of pressure on the pedals.
  • The weight of this cassette is relatively low, without compromising its durability.
  • You need a Shimano MicroSpline body to mount the cassette. So you have to adjust your rear wheel to this.

Lichte cassette met goede schakelprestaties

- Roy 17 March 2026

Prima prijs voor een erg goede cassette. De cassette is makkelijk te monteren en schakelt vervolgens soepel.

Absolutely the right decision

- Steve 3 March 2026

Sram or Shimano? To be honest, the question only arises if you want to use your bike for sport. The shifting behaviour is good with both. As long as you don't buy the cheap models. Sram GX is sufficient everywhere, but if you also want to shift on let and very smoothly, you can't get past Shimano. Whether SLX or XT and of course XTR offer clean performance. Smooth shifting even uphill. For me the best shifting system. I ride MTB Marathon with the XT complete groupset and have had no problems so far. So thanks to Shimano.
