I've had one of these rubber rim valve hole convertors for a while, but just
got around to using it.
The rims on my mtb have different drillings, front to back - which is a
legacy of buying a groupset and wheelset for another frame, the wheelset was
identical to the wheelset on this mtb (Mavic 230 SBPs), but the internet
company that supplied the wheelset didn't supply the same valve drillings
for both wheels (even though I was very specific in my order). I didn't
bother at the time, and because the wheels were identical (bar the hubs
being STX compared with LX, and of course the front having a schrader valve
hole), for some reason I simply can't remember now, I seemed to swap front
wheels between the two bikes. Which, largely, was just dandy given they were
practically identical.
However, fate strikes - the other mtb that I put together, got nicked out of
a relatives garage - uncannily they didn't take the mtb I still have,
despite it being better, more expensive, better equipped and considerably
lighter than the one they took. I can only think it's perhaps because the
other one looked cooler. And this occurred during a period where I must have
had the front wheels on the other respective bikes (inexplicably, now,
because I can't for the life of me remember why I kept doing that...).
So I bought one of those rubber, grommet like valve hole convertors, and a
presta valved inner tube ('cos I just find it easier to deal with the same
valves in front and back). I've just got around to using them, and it's not
immediately apparent from which side of the rim I should insert the
convertor. If I put it in from the rim side, a bit of it sits just proud of
the rim surface, and vice-versa if I put it in from the inner-tube side of
the rim. Now the inner tube valve is practically all metal down to the inner
tube - so no rubber on the valve to get fouled by any expose metal edge of
the rim.
Could some kindly soul let me know which is the best way for the valve hole
convertor to be inserted? And if, ahem, the rubber grommit thingmy suffered
a slight tear, whilst being cack-handed trying to take it out of the rim
again ;-), is that likely to have compromised it at all? It's only a small
tear, it's not falling apart or anything.
Thanks in advance for any help.
