It's no secret 29in wheels weigh more then its smaller counterparts, and, unless you've successfully avoided all forms of cycling media and failed high-school physics, you know dropping rotational weight offers the biggest performance gains. That's what makes the SRAM Rise 60 29in Wheelset so desirable to the off-road crowd. It's one of the few manufacturers producing wheels with a carbon rim.But, this is not some rushed-to-production carbon rim lacking extensive research and design. SRAM awhile back acquired Zipp Speed Weaponry, a longtime (20 plus years) composite component and wheel specialty manufacturing company. This provided them with the expertise to not just enter the wheelset market, it allowed them to offer significantly advanced, highly developed products Like the Rise 60 29in Wheelset.This know-how is evident in the asymmetric shape and impact-protecting HS resin coating on the carbon rim. The asymmetric shape allows SRAM to use near equal length spokes, creating a stronger complete structure. The rim's layers and 3K weave is enhanced to provide strength where the nipples place the most stress to ensure reliability. The Rise 60 uses Sapim CX-Ray spokes that are stainless steel and bladed. These spokes are incredibly strong, aerodynamic, and only weight a touch more than titanium ones. SRAM went with a two cross lacing, using 24 spokes per wheel. This keeps weight down and ensures optimum stiffness to resist wheel deflection. The straight pull design eliminates stress-prone bends to which traditional spokes are subject.The hub shell and freehub body are made of lightweight 6000 series aluminum, and they house sealed cartridge bearings for maximum performance and minimum maintenance. The rear hub uses four bearings and it has an aluminum freehub body to keep weight low. A 54-tooth drive ring gives just under seven degrees of engagement, while three pawls with a saw-tooth profile offers nine points of purchase to give the Rise 60 instant and positive engagement when you stomp on the pedals.The SRAM Rise 60 29in Wheelset is intended for crosscountry race and marathon use. While they're not tubeless ready, they are compatible with tubeless conversion kits such as Stan's No Tubes. They're available with standard quick releases or with 15QR front and 12x142mm rear. The Rise 60 Wheelset is compatible with six-bolt rotors and Shimano or SRAM cassettes.
