A schreader valve that only clears the rim by that margin is TOO SHORT. I've worked on these bikes, repaired flats for that specific bike many times before. WE can pump it up with our compressor. A customer with a floor pump, or a mini-pump or any other of the billion variations of pumps out there might not be able to. Or at worst they'll try and pull the valve out through the rim for more clearance and create a pinch flat.

That is not the correct length valve, and you telling us that you can pump it up makes no ****ing difference.. Any professional mechanic that lets a bike leave with a flat repair like that is a ****ing moron and doesn't deserve the "professional" part of that title.

I'm not sure how may more different ways I can convey this.

Another amusing problem is when the bike sits for a while and the tire gets low. Rider doesn't notice, goes for a ride, comes back, and there isn't a valve stem any longer. Not visible at least. Valve stem is down inside the rim somewhere.... Ever tried letting the air out and putting the valve back through the hole when it's still partially inflated and you can't get to the valve?

Fun.
