Shimano Altus Cassette CS-HG31-8 11-32T

With a 11-32T range, the Shimano CS-HG31 gives you an 8 gear range to use so you’re powering up the hills and flying down the other side. A zinc phosphate finish ensures smooth shifting and long-lasting performance and the enlarged sprocket window design helps keep the weight to a minimum. Made for use with IG/HG chains.
