Speed data straight from the wheel, even when GPS reception drops. DT Swiss and Wahoo have shaped TRACKR SPEED to fit neatly around a compatible SPLINE rear hub, keeping the sensor tucked into the wheel rather than strapped elsewhere on the bike.
It measures hub rotation and sends speed data to a compatible computer or watch over ANT+ or Bluetooth. A rechargeable battery gives up to 94 hours of riding, with the magnetic charging cable included.
This SPLINE version fits SPLINE 350 road disc rear hubs from 2023 onwards and SPLINE 370 from 2026 onwards. These must be 12 x 142mm hubs. Check the exact wheel in DT Swiss Product Support before ordering; a shared hub model name alone does not confirm compatibility.

Connection and battery-status LED
Includes sensor and USB-C to magnetic charging cable
The three-axis accelerometer measures wheel rotation without relying on GPS reception. It gives your compatible computer a wheel-based speed source through tunnels and other places where satellite coverage becomes patchy.
Recharge and ride
A magnetic cable makes charging straightforward, with up to 94 hours of riding from a full charge. The included cable connects to USB-C, and the status LED lets you check the sensor before heading out.
