i76 KOM Light TCS 27.5" Fat Bike Rim

The WTB i76 KOM Light TCS 27.5" Fat Bike Rim is built for riders who want a lighter alloy fat-bike rim without giving up everyday durability. Its open cavity rim design helps reduce rotating weight for quicker acceleration and easier line corrections on snow, sand, and rough trail, while the stout AL6069 alloy is engineered to handle frequent hard use. Tuned around WTB TCS 2.0, it’s a strong choice for riders prioritizing dependable tubeless performance and straightforward serviceability on a 27.5" fat bike build.

• Open cavity rim design - trims rim weight to improve responsiveness and climbing feel on fat-bike tires
• AL6069 alloy construction - balances impact strength and long-term durability for regular trail riding
• Updated spoke bed - provides a more congruent nipple-to-rim interface for cleaner builds and more consistent tensioning
• TCS 2.0 tubeless compatibility - designed for easier mounting and reliable air retention when set up tubeless
• WTB Solid Strip included - creates a smooth interface between tire and rim, and helps protect the tubeless system if a spoke breaks
• Setup note - TCS tape is still required for tubeless installation
