Rider fit: reaching the ground
The Brixton Cromwell 1200 lists a 795 mm seat; the Brixton Crossfire 500 lists 795 mm, within a few millimetres of each other. Seat height is only a first-pass ground-reach input. It does not establish safety or actual foot contact. Seat width, suspension sag, boots, mobility, load, and individual proportions can materially change the result.
