Product Description

Key Features:

  • Close ratio gearing allows a more efficient use of energy through finer cadence control
  • Largest sprockets are mounted on lightweight alloy and carbon carriers to increase rigidity
  • 5 largest sprockets are made from titanium to keep the strength high while still being lightweight
  • Sprockets are extensively cut away and drilled to further shave off the grams without reducing rigidity
  • Nickel-plated finish offers hard wearing resistance to corrosion
  • Alloy cassette lockring
  • For Super Narrow 11-speed HG-EV chains
  • Average weight 175 grams for 11-25 tooth

Occasionally, without notice, manufacturers change product design and/or specifications.

Casettes Guide

What are cassettes?

A bike cassette is the cluster of rear gear cogs attached to the rear wheel.

Who needs a cassette?

Any conventional derailleur-geared bike has a cassette, whether it’s a road bike, a mountain bike or a hybrid. The alternatives are a singlespeed or a hub gear on the rear wheel.

What are the choices?

The main difference between cassettes is the number and size of gear cogs on them. Seven, eight, nine, 10 and 11-speed are the most common.

What should I buy with them?

If you’re replacing your cassette, sometimes you have to replace other parts of your drive train such as your chain or chainrings. This is because they wear evenly together.

Anything else?

With some cassettes you don’t need to replace the whole unit. Instead, just part of the cluster is detachable, so you only swap out the most worn cogs.
