GENERAL TERMINOLOGY OF BICYCLE PARTS

Chapter on individual component areas of the bicycle have more specific terminology and definitions. For the purpose of this manual, the following terms apply to the frame and basic components.

Marzocchi 55 ATA Suspension

Marzocchi’s top-of-the-line, all-mountain fork weighs just 4.6 pounds, yet cranks out an impressive 6.5 inches of travel. On top of that, it comes loaded with a suspension lock-out, variable low-speed compression damping, a quick-release, 20-millimeter thru-axle, and 40 millimeters of adjustable travel. It’s a veritable Swiss Army knife on steroids.

DMR Dirt Jump Wheelset

DMR are well known among dirt jumpers and 4X riders, but this seriously tough wheelset shows they deserve wider recognition. At just over 500g, the new Thret rim is 250g lighter than previous DMR hoops, although chunky hubs and thick 36-spoke lacing mean it’s still an effort to get them going – but these hand-built wheels have proved unfalteringly stiff and strong.
