schrader to presta rim adapter

[johnson..]

Hi
Had a bit of a problem yesterday, luckly i was home and not in the
middle of nowhere. I recently bought a rans tailwind 2001 model new from a
LBS, got a good deal. Of course with all the mods I'm up to the original
price by now.

Anyway on friday I bought a larger rear tire 1.95 (it came with comets
1.35). Installed the tire sunday afternoon with the original tubes (i should
have known better) not a tube made for the larger tire. About 930pm sunday
night i hear a whooossss. Sure enough a tube failure. So I remove the wheel
and tire and put in a new tube with a comet 1.35 not wanting to have another
tube fail on me.

To my extreme surprise the new tube would not fit in the rim adapter. Had to
take the bus to work and home today.

Could have been much worse, could have been in the middle of no where with
not a tube to fit the bike. BTW could i use a presta tube on a rim drilled
for schrader without an adapter??

Anyone else have this problem??

There's a rubber bushing made to take up the space. I've bought a
couple of Presta tubes that came with them, but they can be had
separately from several sources including:

which is

I have also used a thin general-purpose grommet of the appropriate
size; 1/4"IDx3/8"OD. All it does is keep the Presta stem centered in
the hole and prevent chafing of the tube at the base of the valve.

Yes, I have had this problem, or something similar when I flatted and
discovered that my brass adapter had corroded to the valve stem, and I
couldn't separate tube and rim. In my experience, you can use presta tubes in
schraeder drilled rims without any adapter, I have several bikes like this,
since wheels came drilled that way and I don't like having to carry both types
of tubes.

Cool, thanks. I was worried that maybe the tube would try to squeeze out
through the schrader size hole.
