The Shimano Deore XT WH-M8120 Wheelset brings a classic name to your trail bike, with a 30mm internal width for stability and toughness. These wheels are light enough to really feel fast on a climbs (with 9 degree engagement for the tricky root sections), but strong enough to rail a high speed corner. They're perfect for trail riding, in other words. A new wheelset is the quickest way to upgrade your bike, and Shimano XT is known as a better-for-cheddar champ across all components.
