The WTB ST rims create an affordable solution to the previously cost-prohibitive hurdle of tubeless mountain biking. UST compliant bead hooks border a tape and sealant-driven inner rim profile, providing standards-based, repeated tubeless consistency. Enjoy the benefits of tubeless riding without breaking the bank.

Features:

TCS: The tubeless-compatible TCS rim profile is specially designed for TCS or UST tyres and is also compatible with tube-type tyres when used with tubes.
I-Beam: The I-Beam adds strength to the inner rim cavity. This distinctive, centrally located vertical support counteracts spoke loads and provides lateral rigidity.
4D Drilling: WTB's spoke holes are drilled at the precise departure angle to align spoke head and nipple with hub flange, eliminating binding and lateral loading while also dispersing the load more evenly over a greater area. This prolongs the wheel’s lifespan and increases stability.
WT69 Alloy: WT69 Alloy has a 20% higher yield than 6000 series Aluminum alloy and is so strong that it can be extruded into lighter rims that are tougher and stiffer than their heavier competition.
