Riders who spend a lot of time in the 42T can wear out their Aluminum sprocket faster than the rest of their cassette, which is all steel. Instead of throwing away a $400 USD cassette that’s 90% good, the X-Cog gets you riding again for only $108.
The X-Cog provides more range, not just an easier granny gear. Perfect for steep terrain The increased range is a must for racers looking to maximize their chainring size for timed downhill sections, while still being able to conserve energy on transition stage climbs.
