Quarq for Cannondale Power Meter


Built on Quarq’s latest technology platform, the Quarq for Cannondale Power Meter replaces the factory spider on Cannondale's Hollowgram SI, SL and SISL2 cranksets. It features Power Balance™, OmniCal™ and improved clearance for oversize frames and bottom brackets. Accuracy is +/- 1.5% and ease-of-use takes center stage with the prominent ANT+™ ID, LED indicator and tool-free, user replaceable battery.

The Quarq for Cannondale Power Meter is available in full size (130 BCD) and compact (110 BCD) bolt circle diameters, and comes in three different forms: Power meter spider only, power meter spider with chainrings, or as a complete assembly comprising power meter spider, Hollowgram SL cranks, Cannondale ceramic bearings and SRAM TSM or Stronglight CT2 chainrings. At 679g with SRAM TSM chainrings (130 BCD, 172.5mm), this is the lightest Quarq power meter available.

Quarq offers a spider removal and installation tool so the power meter can be installed at your local bike shop. The alternative is to ship your cranks to the Quarq factory for installation, which is a free charge, plus shipping.
