Majoni unique design
Durable brass manufacture
Fits all Majoni fenders
N.B. Do not open the non return mechanism (flap) by pushing it too far with a metal pin or nail, because this may damage the valve.
Try to avoid deflating any of your Majoni fenders, but if you find it necessary, probe into the valve with a biro pen, pushing only the minimum distance possible to gently open the non-return mechanism and listen for the air escaping.
Majoni recommend an optimum inflation pressure = 0.2 bar - at this pressure it should be possible to visibly press in the fender wall with the flat of your hand
