Are you using the lever less technique for putting the tires back on? It makes the odds of pinching the tube during the change over tiny. It works especially well with mountain tires.
Though for some reason I thought you ran tubeless.
I don't run tubeless yet but my next bike will. I almost got the tire back on without using a lever but I did one final, super careful lift with the lever. It could have happened then (and that was 'Bent's guess) but it's not close to where the puncture was. I'm thinking it's more likely that the tube I've been carrying around forever got some abrasion from the multi-tool over a few years of riding.
if it's the truth you seek I'm sure someone in your household who repairs tiny imperfections on a daily basis could determine the root cause.
He sought the truth immediately, locating the puncture with the help of the dogs' wading pool. It's 15-20 cm away from the place where I used the tire lever for one final lift. There were no other witnesses to that moment so that's as close to the truth as we will ever get.
The important takeaway is that I should never get a flat tire in a solo race. Or maybe just buy a new bike the next time I get a flat.
Yes, a new bike would surely fix your flat. ;-)
:) I've been on the lookout ever since you made a snide comment about a photo of my bike last fall. Then when I raced this year, I saw that I have no hope on my 26er compared to other riders when we get to roads and non-technical trails. So I'll admit my first thought yesterday was, "Hobble home on the damned bike and spend the afternoon shopping." :) There isn't much selection at this time of year though, so I may have to settle for doing research in preparation for spring 2017.
Not as much fun when you've been riding through horse poop.
I've found the secret to not needing tire levers is how much air is in the tube. This video shows quite a bit of air. I tended to want a reasonably full tube because it seemed like that would keep it from getting trapped between the bead and the wheel, but the trade-off is that the more air you have in the tube, the harder it is to get the bead on the opposite side to sit deep in the V of the wheel to give you enough to work with to get the last bit over the edge of the wheel. Now I put just enough air in the tube to take the folds out of the rubber.
And yes, your repair bag gets pretty big by the time you add cleaners and a brush to get all the ick off your tire before fixing a flat. I think I've changed 5 tires this month. I'm hoping to be done for the year.
I didn't have that much air either. Whether or not the tube was damaged in the seat bag before yesterday, there is no argument that I suck at bike repairs.
I usually keep my spare tube wrapped in a freezer-weight zip loc bag so that the bag takes the abrasion in the seat pouch instead of the tube getting abraded.... and I end up having to change the bag every year or two because it does get rubbed by the other things in the seat pouch.
I've often used levers cautiously for the initial removal and getting the last bit of the bead on the rim, without issue.
And I've had very almost no flats since switching to tubeless and Stan's sealant many years ago.
My spare tube was heat sealed in thick plastic but it had been abraded over time. I should have re-wrapped it like you do.
Amen to tubeless and Stan's!
