WTB LaserDisc XC Rear Wheel

WTB's lightest hoops, the LaserDisc XC at 425-grams, laced with 28 WTB double-butted spokes to LaserDisc Lite hubs. This elite-level wheelset combines race-winning acceleration with long-term durability.

Because WTB designs and manufactures 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. Some brands fit so loosely that they easily fall right off the rim. WTB rims and tires feature a consistent interface for easy installation and increased safety.

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

Unbendium Bulge:
An additional band of aluminium added to the rim’s sidewall that counters torsional, radial and lateral flex. This rib, which replaces the braking surface, provides an impressive boost in strength with a negligible difference in weight. This WTB innovation is found exclusively on LaserDisc series rims.

GBS:
WTB's proprietary Global Bead Seat design utilizes deeper grooves for the bead seats as well as two raised lips that lock the tyre's beads into place on the rim. GBS holds the tire firmly in place and greatly reduces the chance of 'burping' the tyre off the rim in heavy lateral loading.

WTB Double-Butted Spokes:
LaserDisc wheels are built with top-quality WTB-branded spokes. These premium double-butted spokes are much thicker at the J-bend (the weakest point on the average spoke), yet they still weigh less than standard spokes. WTB spokes are 2.5 millimetres at the elbow, where standard double-butted spokes are 2.0 millimetres at this point. These small differences add up to a stronger, stiffer wheelset.

12 Point Engagement:
Each LaserDisc rear hub features a cold-forged, fully machined aluminium hub shell and alloy freehub. Power transfer is driven through six, double-sided pawls, totaling 12 points of engagement.

Sealed Cartridge Bearings:
LaserDisc rear hubs roll on four sets of sealed cartridge bearings and front hubs utilize two sets of sealed cartridge bearings. All bearings are stainless steel.

Easily Adjustable:

Bearing preload is easily adjustable on LaserDisc Lite hubs through the adjustment nut and locknut.
