WTB KOM Light i25 29" is a lightweight alloy MTB rim built for modern trail riding, pairing a low-weight open cavity profile with durability-focused spoke bed design and WTB TCS 2.0 tubeless performance. With CVX spoke hole technology and an updated spoke bed interface, it’s designed to build into a reliable 29er wheel that stays true, seals tubeless more consistently, and stands up to day-in, day-out trail use.
Open cavity KOM Light design - trims rotational weight for quicker acceleration and easier climbing without giving up trail-ready support
CVX spoke hole technology - improves spoke/nipple alignment and reinforces the rim at the spoke holes for more consistent builds and better long-term durability
AL6069 alloy - sturdy material choice intended to handle regular trail-bike impacts and hard riding
Updated spoke bed interface - more congruent nipple-to-rim contact for smoother tensioning and fewer build-related stress points
TCS 2.0 tubeless-ready system - engineered for easier tire mounting and reliable air retention compared to traditional tubeless setups
WTB Solid Strip included - creates a smooth internal surface and helps protect the tubeless system from air loss caused by a broken spoke
Setup note - TCS tape is still required for tubeless installation
