Often these get ruined by misguided attempts to inflate the fender with a needle shaped pump adapter which damages the innards. They should be removed or inserted with an M3 screw. A few years ago I could buy these brass valves online for less than £1 each but I've used them all up now. Swindleries charge anything up to £25 each but the postage makes it extravagant to buy them that way. Can anyone suggest an economical way to but a half dozen or so of these?
