WTB Rim KOM Light 29'' i21 28h

Our exclusive 4D spoke drilling system prevents the spokes from binding and side loading, while the spoke base itself has been updated to provide a more compatible interface between the spoke and the rim. The integration of the all-new Solid Strip on our TCS 2.0 rims offers the easiest to fit and most reliable tubeless system we've ever made. Available in widths from i21 to i45, because all bikes should benefit from lightweight rims.

Features:

• TCS 2.0 creates a stronger, easier to install and more reliable tubeless system.
• A recessed channel along the center of TCS 2.0 rims allows for the installation of the all-new solid strip, which prevents the tubeless strip from sagging at the spoke holes and provides a smooth, consistent interface between the tire and rim.
• The 4D angled spoke hole eliminates binding and side loading, and disperses tension more evenly over a larger area.
• Disc brakes only.
• KOM Tough rim weights include the solid band installed on each rim.

A recessed channel along the center of TCS 2.0 rims allows the installation of the all-new solid tape, which prevents the tubeless tape from sagging at the spoke holes and provides a smooth and consistent interface between the tire and the rim. The installation of the solid tape allows the more flexible and easy-to-install Flex tape to provide the tight seal needed for a tubeless system.
• I-Beam: The I-Beam reinforces the inner cavity of the rim. This distinctive support counterbalances spoke loads and provides lateral stiffness.
• 4D Drilling: The spoke holes are drilled at a precise starting angle to align the spoke head and nipple with the hub flange, eliminating binding and side loading while distributing the load more evenly over a larger area. This extends the life of the wheel and increases stability.
