Episode notes
Fix Seat Height First
- Do prioritise lowering a saddle if it feels too high; Stanbury finds seats are commonly too high or too far back.
- Check cleat fore/aft and arch support simultaneously because they interact with saddle height.
Pelvis Rotation Changes Effective Fit
- Pelvic rotation changes your effective seat height and setback as you move between hand positions.
- A single bike setup is always a compromise between tops, hoods and drops because hip center moves in an arc.
Q‑Factor Fix Gave 10% Power Boost
- Stanbury moved a rider's Q-factor wider and pain disappeared overnight; the rider then raised 20-minute power from 400W to 440W in six weeks.
- The gain likely came from symmetry and better posterior chain engagement rather than training alone.
