•Saddle height is BB-centre to the top of the saddle, measured along the seat tube — set it, then check for a slight (25–35°) knee bend at the bottom of the stroke.
•MTB riders often run a touch lower for control on descents and shorter cranks for pedal clearance.
•Change one thing at a time and give your body a few rides to adapt.
