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??

??? I'm a little confused. You bought a tube with a Presta valve and
it didn't fit through the adapter in the rim? That's a little fishy-
every Presta valve I've seen is the same diameter.

Could the adapter have gotten banged or bent somehow? In any case, I'd
ream out the adapter a little, just to give yourself some wiggle room.

You can put a Presta tube in a Schrader rim without an adapter, but
the edges of the rim hole will tend to cut the tube. Annoying at best-
it's impossible to patch a hole there.

The original presta valves fit fine, the ones i bought at the LBS did not
fit. The nut fits fine on the threaded valve but these tubes will not fit in
the adapter.

The adapter isn't damaged at all because the original tubes on the bike fit.

Better with the bike parked than on the front wheel of a Rocket at 25
mph.

I replaced the tube and re-inflated the tire just in time to make it to
the start of the Thursday evening club ride. I only received minor
abrasions - more importantly my Rocket was undamaged except for
scratches on the left pedal and left side water bottle holder.
