SRAM unveiled a 650b version of their Rise 40 wheelset. The aluminum wheelset shares the same rim profile of the 26 and 29-inch Rise 40 wheelsets: 19mm inner width; 24 bladed spokes laced two-cross, front and rear; and compatibility with quick-releases or thru-axles.
Weight is not finalized—it’s a safe bet the 650b version will fall somewhere between the 26 and 29-inch wheelsets. A tubeless kit is in the works as well.
One thoughtful addition to all the Rise wheelsets is a red decal that indicates the size of the wheel.
