Read published geometry

Compare stack, reach, wheelbase and angles only where the source records a value.

What the numbers describe

Reach and stack describe the frame reference position, while wheelbase, chainstay length, head tube angle and trail describe the relationship between the contact points and steering axis. These measurements explain geometry; they are not a universal fit or handling score.

Compare like with like

Geometry changes with frame size, wheel size, tire choice and model year. Use the same size and configuration when comparing bikes, and keep manufacturer-published values separate from RideDNA-derived calculations.
