What it does: replaces the flat ankle plates with a cupped heel rest with side limiters, holding your heel in a fixed lateral position on the moving Active Heel Support. Recommended for endurance racers and anyone with heel soreness — one customer with left-heel pain during endurance stints called it “perfect now.”
Sizes: 80 mm and 100 mm width. Rule of thumb from the community: 80 mm keeps the foot straighter (typical brake foot), 100 mm suits a slightly angled foot (some prefer it on throttle).
Install (5 minutes):
- Remove the Active Heel Support carbon plates.
- Unscrew the 4× M4x8 bolts and remove the ankle carbon plates and ankle filler.
- Place the heel cup on the aluminium A.H.S base — the curved wall faces down (there’s an arrow on the cup).
- Mount with the same 4× M4x8 bolts — just enough torque, don’t crack the mount.
- Press the two bolt covers in with your fingers (friction fit).
