WTB SpeedDisc i19 29" MTB Rim

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.

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.

WTB SpeedDisc Rims feature pinned/sleeved joint and eyelet spoke holes.

• Disc-specific
• International Bead Seat (IBS) - two raised bumps on the interior of the rim that keep the tire's bead from being pulled away from the hook during heavy lateral loading
• All WTB rims that use the International Bead Seat (IBS) should use an 11mm rim strip
