Short Valve 700c Inner Tubes

Would be grateful for any information please where to get hold of good quality 700c x 23mm inner tubes with SHORT Presta valves for my 1970s/80s road bikes. To suit the shallow classic rims (such as Mavic G40) the valves need to be about 25 mm and no more than 28mm long - but can't find any anywhere these days ! All help gladly received

    Drop by your nearest Halfords. I think these might be suitable but at least with that type of packaging you can check out the length of the valve fairly easily.

    All valves now are at least 40mm long now. There might be some brands doing 35mm long valvesd tubes about but shorter is extinct now.

    Sadly you seem to be right. I've broken several 35 mm valves for the simple reason that the stems flex in the rims when a push-on pump is used at the roadside. And no self respecting racing cyclist ever uses retaining nuts on inner tubes ! I'm surprised no manufacturer is producing short stem valves again with the growth of "fixies" using vintage frames and often wheels, and a resurgence of interest in classic road bikes. By comparison, vinyl records and now even cassette tapes are back in production because retro is in vogue :)

    Thanks I'll certainly give it a go ! Perhaps us vintage bike enthusiasts should do what classic car clubs do - get together in a buying syndicate and have a batch of suitable inner tubes manufactured. I've often bought such parts for my cars and it's surprising how cheap they can as it's done on a not-for-profit basis :)
  • There arent enough vintage bikes to warrant production (but if you feel there is a niche in the market why not set up a business to manufacture them)?. 42mm is as short as they go.

    Two options spring to mind to avoid the problems you describe with the longer valve stems. First is to switch from a push on to a screw on pump for roadside puncture duties. I've used Lezyne pumps over the years and found their screw-on design to be more reliable than many of the push-on types. Their mini HV pump is worth a thought

    Also I still use the valve stem locking nuts to prevent any instability. Maybe I'm not a self-respecting racing cyclist but, hey-ho, who's going to notice when I'm on the move.
