SRAM RISE MTB WhEElS
Quicker acceleration. Effortless climbing. Pinpoint cornering precision and more controlled descending. it’s no secret—these are the traits that make you a smoother and fasteroff-road rider. they’re also the reason SRAM created RiSe, an all-new off-road wheelset that optimizes performance for the XC rider and racer. to create RiSe, the SRAM product development team took ascientific approach to engineering a better wheel.

they focused on six fundamental factors that affect the wayyou ride: weight, inertia, engagement, lateral stiffness, frontal stiffness and efficiency. “A lot of wheel companies tend to focus on one design attribute on their wheels, such as low weight or lateralstiffness,” said SRAM wheel product Manager Bastien donzé. “our goal from the start was to design a wheel that offers all the best possible ride characteristics.”

Knowing that light weight is agood thing, but not the only thing, SRAM focused on finding the perfect balance of weight and strength. they engineered, tested and finetuned rim designs for both the 26-inch and 29-inch RiSe wheelsetsto achieve lower inertia for snappier acceleration and increased efficiency. the result was two final formulas—one for the RiSe 60 carbon wheel, aimed at XC racers and performance-obsessed riders, andthe other for the RiSe 40, the aluminum wheel which targets versatile XC all-arounders. taking the science a few steps further, engineers also studied the affects of various hub and rim materials,flange designs, spoke angles, as well as rim thickness and shapes, to create optimal all-around stiffness. Both RiSe 60 and RiSe 40 hubs are beautifully carved from aluminum for optimal weight andenergy transfer. encased in the Rise 60 hub is a unique pawl design that maximizes efficiency and power, making the most of every pedal stroke. the sum of these efforts—the blending of engineering...
