Seatpost bag warning

I've got a mini Trek seatpost bag that fits a multi-tool, spare inner tube etc. Last week I was on a brilliant riding tour in the Alps, so took the precaution of putting a 2nd inner tube in the elasticated holder that fits on the bottom outside of the bag. I've done this before, no problem.
Don't do it, is my advice.
While descending from the col de la Madelaine, the tube worked its way loose on some poor road surface, and dangled into my rear wheel. Thankfully it didn't lock it straight away, with gradual slowing from about 50kph before it suddenly locked, flatspotting and blowing a dirty great hole in my rear tyre. In the resulting loss of control as my back wheel slewed out, somehow the spokes on my front wheel pushed through the rim tape and blew the front tube as well. Amazingly, I stayed upright.
The funny thing about this incident is that I managed to destroy 5 inner tubes in one incident: one got shredded as it got stuck in the back wheel, two tubes blew in the incident and two more went as I inflated the front wheel before realising there were two holes in the rim tape.
The worrying thing is that the incident could have been so much worse. I'll never put anything in that elastic loop again, and would advise all you out there to learn from my mistake....

If you would have put the tube in a small plastic bag & then in the loop, the worst that would have happened was the loss of a spare tube :shock:
Glad your alright0 -

Yup good advice. Actually,although I alway have the tube tightly bound in an elastic band I have previously (but not on this occasion) then put a loop of string through the middle of the tube, to stop it falling loose. Still, I'm always going to use the back pocket from now on...0 -
If you have a fi'zik saddle they have a really good clip system for bags - pretty neatCannondale Supersix / CAAD9 / Boardman 9.0 / Benotto 30000
