WTB LaserDisc i21 29" MTB Rim - Black

WTB LaserDisc i21 29" MTB Rim

I-BEAM The I-Beam, found exclusively on STRYKER Wheels and LaserDisc series rims, was pioneered by WTB in 1994. This distinctive, centrally located vertical support counteracts spoke loads and provides torsional rigidity.

UNBENDIUM BULGE An additional band of aluminum added to the rim?s sidewall that improves torsional, radial and lateral strength. This rib, which replaces the braking surface, provides an impressive boost in rigidity with a negligible difference in weight. 

TCS The tubeless compatible TCS rim profile is especially designed for TCS or UST tires and is also compatible with tube type tires when used with tubes. TCS rim profiles feature superior tire retention capabilities. When mounting a TCS or UST tire on a TCS rim profile very little initial air pressure force is required to inflate tire. In most cases a small mini hand pump will provide ample air flow for inflation. 

THE WTB DIFFERENCE Because WTB designs both tires and rims, we can focus on a consistent interface between the two. While all mountain bike tires are based around an established bead seat diameter (559-millimeter for 26-inch tires and 622-millimeters for 29er tires) you?ll find a wide variance in many brands. Some brands of tires fit rims so tightly that tools are necessary for installation, while others have a looser fit. WTB rims and tires feature a consistent interface for easy installation. TCS rim profile WTB 29er rims feature a 622-millimeter/700c bead seat diameter, and a minimum bead opening of 21-millimeters. This minimum width is the defining element that separates 29er rims from 700c trekking, hybrid and road racing rims. Narrower rims are not designed for today’s wider 29er tires.

WTB RIM STRIPS Proprietary WTB rubber rim strips are 11-millimeters in width and are designed to compliment GBS Equipped rims. We recommend using these strips with any WTB rim, as wider rim strips can interfere with the tire’s bead seat.
