SKS MV Easy Workshop Presta air release adapter

This adapter solves the problem with the SKS MV Easy Heads not allowing air release on the presta side due to their specific design. The valve is opened with pressure and not mechanically. The adapter decreases the distance between the presta piston and the valve and thus opens the valve through contact. The Fusion design is parametric: use h_total and h_low to adjust the total height and the height of the first step. h_total = 6.5 mm and h_low = 4 mm worked for me. if h_total is set to high, the schrader side will not work anymore. With my design, both sides work.

Instructions:
Put the adapter with the smaller diameter side down below the rubber gasket inside the head (presta side). Re-assemble as usual.
