Quarq for Cannondale Quarq Power Meter

The Quarq power meter for Cannondale's Hollowgram SI, SL and SISL2 cranksets features Power Balance™, OmniCal™, light weight and improved clearance for oversize frames and bottom brackets. Coming in full size (130BCD) and compact (110BCD), it is compatible with a wide range of chainrings.

This design uses aluminum-armored, integrated electronics and lifts accuracy to +/- 1.5%. Ease-of-use takes center stage with the prominent ANT+ ID, LED indicator and Quarq’s tool-less, user replaceable battery.

The Quarq for Cannondale Power Meter is available as a spider fitted to your own Cannondale Hollowgram cranks, as a spider with chainrings, or as a complete assembly comprising Hollowgram SL cranks, Cannondale ceramic bearings and SRAM TSM or Stronglight CT2 chainrings. At 679g with SRAM TSM chainrings (130BCD, 172.5mm), this is the lightest Quarq power meter available.

For installation on existing cranks, 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 the cranks to the Quarq factory for installation, which is a free charge, plus shipping.
