The Quarq ELSA 10R is adaptable, lightweight and strong plus has the latest Quarq technology. ELSA 10R packs a four-pronged punch to elevate bike and rider performance. The subatomic spider houses integrated electronics which minimize interconnections and reduce exposure to the elements, bringing unmatched durability and reliability. A user replaceable CR2032 battery, LED indicator and visible ANT+ ID make servicing and installations a snap.

Power Balance™ captures left and right drive strokes. OmniCal means you can change chainrings with no compromise on accuracy. Exogram™ Hollow Carbon crank arms by SRAM reduce weight and increase stiffness. New stress flow lifts accuracy to +/- 1.5% and makes power measurement independent from chainring selection.

The Quarq ELSA 10R power meter is officially compatible with all SRAM Red, SRAM Force, SRAM Rival and SRAM Apex Front Derailleurs. Most mechanics find the ELSA works great with other drivetrains too. More subtle branding and graphics on the ELSA allow it to cosmetically match virtually any bike and drivetrain.

Compatible with SRAM/Truvativ GXP bottom brackets sold separately. Also requires an ATN+ computer like a Garmin Edge 510 sold separately. Compatible with TrainingPeaks analysis software.
