Highlights

Why we rate it

Built for XPLR

Sets the wider 47.5mm chainline used by SRAM's 1x XPLR gravel drivetrains and Red XPLR DUB Wide crank arms.

Dual-sided data

Reads power at the spider from both legs, so you get total watts and left/right balance.

Thread Mount rings

Chainrings from 38T to 46T screw straight on, making it simple to change gearing for different courses.

Low maintenance

Automatic MagicZero recalibration, temperature compensation and a user-replaceable CR2032 cell.
