When SRAM acquired Zipp, a longtime 20 plus years composite component and wheel specialty manufacturing company, it also acquired the expertise to not just enter the wheelset market, but to offer significantly advanced, highly developed products like the Rise 60 Wheelset. The Rise 60 uses carbon fiber for the rim to give it incredible strength and a low rotational weight. It should be noted that Zipp has been building carbon rims for road applications for some time now. This know how is evident in the asymmetric shape and impact protecting HS resin coating. The asymmetrical shape allows SRAM to use near equal length spokes, creating a stronger complete structure. The rim's layers and 3K weave are enhanced to provide strength where the nipples place the most stress to ensure reliability. The Rise 60 uses Sapim CX Ray stainless steel and bladed spokes. These spokes are incredibly strong, aerodynamic, and only weigh a touch more than titanium ones. SRAM uses two cross lacing with 24 spokes per wheel. This reduces weight 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 Carbon instant and positive engagement when you stomp on the pedals. The SRAM Rise 60's are intended for cross country race and marathon use. While they're not tubeless ready, they are compatible with tubeless conversion kits such as those from 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 ...
