Was out riding with my son on new/in progress built trails im helping build. First time there. As any would know new trails are a bit rough. He was on a trek mt60 with new xr1 "comp" 20" tires.
Ride was fine till very large root (looked more like half buried tree lol) which I went over no issue then son followed behind. His rear slid (its off camber on top of being rather large) and bounced causing him to fall over just after clearing it.
We went to take off again and he hollars his rear tire is making a funny noise, the way he described it said "flat" to me, had him check, it was.....
Ok so trail side tire repair, no buggy, good time to teach him. Except couldn't find a puncture anywhere. Wasn't about to waste a CO2 for no reason. Luckily that root was right near park paved paths and short walk back to trailhead.
Got back to car, took everything apart and inspected closely, not only no puncture but tube was holding some pressure, what remained after initial loss I guess. Inspected tire insanely close, nothing, squeezed the tube and ever thing, no more air loss.....WTF????
His mom calls saying I need to bring him home, so we load up, I drop him off and come home. Spent 20mins inspecting things again in the garage, nothing, so air up tube alone unmounted. No leaks!!!! Even checked with soapy water. WTF IS GOING ON????
Tube is older and just tried to take valve core out (Schrader) and can't, its bent or something, off to one side inside the stem can't get tool in.
Could the impact and bounce have jarred the stem that much??? Did we walk out for nothing when I have co2s I carry on me??? And would adapting his wheels to presta (if I can find 20" presta tubes that aren't way overpriced) avoid a repeat of this?
