Why a GRAVA.

KevTex tips
Kevlar reinforcement at the crank arm tips, against rock strikes and impacts.
Stiff under torque
Mitsubishi Pyrofil carbon layup, tuned for sustained torque on rough ground.
Calm on rough ground
The layup controls vibration on uneven surfaces, hour after hour.
29 mm spindle
29 mm DUB spindle, compatible with SRAM DUB bottom brackets.
Chain stays on
Narrow-wide Direct Mount chainrings in 40, 42 or 44T, for secure retention in 1x.
Gravel chainline
47 mm chainline, for wide gravel rear spacing.
