|Features||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. This WTB innovation is found exclusively on STRYKER Wheels and LaserDisc series rims.
GLOBAL BEAD SYSTEM WTB’s proprietary G.B.S. design utilizes deeper grooves for the bead seats as well as two raised lips that lock the tire’s beads into place on the rim. G.B.S. – featured on LaserDisc, SpeedDisc and Dual Duty series rims – holds the tire firmly in place and greatly reduces the chance of ”burping” the tire off the rim in heavy lateral loading.
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.

12 POINT ENGAGEMENT Each LaserDisc rear hub features a cold-forged, fully machined aluminum hub shell and alloy freehub. Power transfer is driven through six, double sided stainless pawls, totaling 12 points of engagement.
SEALED CARTRIDGE BEARINGS LaserDisc rear hubs roll on four sealed cartridge bearings and front hubs utilize two sealed cartridge bearings. All bearings are stainless steel.
EASILY ADJUSTABLE Bearing preload is easily adjustable on LaserDisc Lite rear hubs through the adjustment nut and locknut.
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.
SIDEWALL WEAR INDICATOR This feature–found on Dual Duty, DX series rims–is a groove in the braking surface that, when it no longer exists, indicates that the rim needs to be replaced due to sidewall wear from the use of rim brakes.
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.
WTB Tubeless Valve New Taper Design allows for optimal fit on a wide variety of rim. Removable valve core for easy cleaning and un interrupted air flow. WTB Tubeless RIm Tape Light, strong, and extra sticky for durable long lasting leakproof performance.
Swell-Bow WTB spokes are better by design. At the J-bend—the most likely point for the average spoke to break—these spokes measure 2.2-millimeters in cross-section. We call this proprietary feature Swell-Bow. These thicker elbows fit perfectly into the hub, providing a stiffer, snug fit. The length between the J-bend and the head is critical. Achieving a snug fit increases strength because stress is spread throughout the form fit.
Double Butting From the 2.2-millimeter Swell-Bow, WTB spokes taper down to 2.0- millimeters, and finally measure 1.8-millimeters at the center. From the mid-point, the spoke tapers back to 2.0-millimeters at the thread. Butting the spoke in this fashion combats the immense stress the spoke sees at both ends. A narrow mid-section greatly reduces weight without compromising strength. WTB spokes can be used with standard hub flange spoke holes.
SPOKE NIPPLES Our new Stryker wheelset uses Sanvic triple butted 3 mm bladed spokes.
