SRAM PG-950 Cassette
For bomber performance without the bling, the 950 cassette gets the job done and will keep doing so for a long time.
When servicing your bike, it's hard to go past SRAM Components for quality gear that's designed to last. A high-end bike is nothing without high-end components and even something as simple as a worn cassette can make the difference between mis-shifting or powering past your mate on that steep climb. Worn gear cables, a stretched chain and rough cassette teeth can all contribute to ghost shifting or dropping a chain, and are the key parts linking your pedal power to the wheel. Thankfully, SRAM offer a full range of quality chains & cassettes for every pricepoint, so you can ensure your gears are running smoothly and dependably.
We won't get into the whole SRAM Shimano debate, though we will recommend sticking with the one brand for driveline components for optimum performance (eg; using SRAM cassettes with SRAM Chains). You will find that SRAM shifting is very positive and solid regardless of the conditions, and will give you many miles of dependable service.
