Gravel bike fit calculator and size guides
Gravel fit is not road fit with wider tyres. The calculator targets a slightly higher, shorter front end and much less bar drop than road, so the same rider often ends up with a different setup — and sometimes a different size.
How gravel bike fit is calculated
The engine applies gravel-specific assumptions: bar-drop targets sit well above road at the same aggression level, stock cockpit assumptions use gravel bar proportions, and the frame evaluation weighs reach slightly differently than road. That is why a road result does not transfer 1:1 to a gravel frame.
Race gravel and adventure (all-road) gravel are scored by the same engine, but their geometry differs: race gravel runs a lower, longer front end, all-road runs taller and shorter. The fit report tells you which family the selected frame belongs to and what that means for spacers and stem.
Race gravel vs adventure gravel
Every gravel model in the catalog is tagged as race or all-road geometry, and the fit report explains what that family means for your spacer stack and stem choice.
This model uses race-gravel geometry: the front end sits lower and longer than typical adventure gravel. Reaching a relaxed position may take more spacer stack or a shorter stem than an all-road frame, and the upward adjustment room can run out sooner.
This model uses all-road / adventure-gravel geometry: the front end sits taller and shorter than race gravel. A relaxed position usually needs fewer spacers here, while a very aggressive target is more often limited by stem length than by stack.

This bike balances stability, comfort, and efficient power transfer for mixed-surface riding.
FAQ
Is gravel bike fit different from road bike fit?
Yes. Gravel positions run higher and shorter, with noticeably less bar drop for the same rider and aggression level. The calculator applies gravel-specific targets and stock cockpit assumptions instead of reusing road numbers.
Race gravel vs adventure gravel: which fit do I need?
Race gravel geometry sits lower and longer, closer to a road position; adventure / all-road geometry sits taller and shorter for long mixed-surface days. If you want a relaxed position on a race gravel frame, expect more spacers or a shorter stem — and check the fit report for adjustment-room warnings.
Can I size a gravel bike from my road size?
Only as a first guess. Stack, reach, and front-end height differ enough between road and gravel that the same size label can produce a different position. Run your measurements against the actual gravel model instead.
