MTB tubes with smooth presta valve stems?

[__PG__]

Can anyone recommend some non-threaded presta MTB tubes? (29er / 700c).
And tubes suitable for touring (700/37 ish) when I put slicks on it for commuting?

I use Michelin A2 tubes for the roadie (700 25-32) but the A3 model (35-37) has a threaded valve stem.
I find the threaded valve stems shred the rubber connection in my Silca floor pump.

You could probably use the roadie tubes for 37cm tyres. 50mm and up would probably be too much of a stretch (pun intended)

For the record Cell Bikes sourced me some Rocket branded tubes in 700x35-40mm with smooth 48 mm Presta valves. These are perfect when I'm running slicks.

Still haven't the equivalent for MTB tires (i. 700x50 ish)

i ran some latex tubes for a while, think they were michelins, green in colour and non threaded valve stem. they were mtb tubes, not sure if you'll find them in the size you need, but maybe look up michelin

Foss tubes are smooth valved. So are many cheapie Cheng Shiang variant tubes in this size...but I can't recommend them...

BBB tubes I think are thread less. Try Cecil's in the city
