SRAM’s Quarq power crankset is compatible with all of SRAM’s road groupsets, and the cranks feature SRAM’s integrated carbon crank arm and SRAM’s proven RED chainrings. The Quarq is the lightweight leader for wireless power devices and installation and battery change-outs are simple, plus ANT Wireless compatibility makes gives it the flexibility to sync with nearly any display unit.
Quarq established its factory in Spearfish, South Dakota in early 2007, demonstrated prototype power meters at Interbike the same year, shipped the first CinQo power meter by June 2008 and in May 2011 was acquired by SRAM. In a short time, Quarq’s dedication and expertise has placed it at the forefront of bicycle power meter technology. Today, professional cycling teams, Ironman champions and Olympic gold medalists ride and race with Quarq power meters.
A power meter enables you to monitor and adjust training and racing effort, and energy expenditure, more accurately than ever before. It measures the actual and immediate effort used to drive the bike forward. Power meters deliver hard data for a finish line sprint and capture the effort the moment you attack on a climb.

GXP - Giga X Pipe External Bottom Bracket Bearing Assembly. While other systems rely on side loading the bearings to eliminate play, which causes premature bearing wear, the GXP system is different. The GXP system captures the left side bearing between the spindle and the left crankarm while allowing the drive-side bearing to float axially on the spindle, thereby eliminating the necessity to side-load bearings during adjustment. The simplicity of installation is refined: once it is tightened to the proper specifications you are ready to roll with a worry free BB. The GXP system uses two bicycle specific cartridge bearings and eight seals for a smooth and long lasting ride.
