Calculation method
Calculation method
Bike-only compression (mm)
Extended−bike-only reference length.
Rider-loaded compression (mm)
Extended−rider-loaded reference length.
Rider-loaded compression/travel (%)
100×rider-loaded compression/travel.
Additional rider compression/travel (%)
100×(bike-only length−rider-loaded length)/travel.
Remaining measured travel (mm)
Travel−rider-loaded compression.

Assumptions & limits
Assumptions & limits
- Compares measurements taken along the same suspension axis. It does not choose a sag target or translate fork/shock measurements into wheel travel.
