Product description

Quarq’s ELSA RS packs a four-pronged punch to elevate performance for the Shimano® equipped bike and rider. Specially designed to accommodate Shimano’s 4-arm Hollowglide™ chain rings, the spider houses integrated electronics, a CR2032 battery, LED indicator and visible ANT+™ ID. Quarq’s new multipoint, active temperature compensation fine-tunes accuracy and consistency, making this our most exact power meter to date.

  • 10K™ temperature compensation eliminates temperature effects on power measurement.
