Tube blowout cause - your analysis please
On my first lengthy ride with my new Mavic Open Pro wheelset and my Gazelle Champion I also experienced my first blowout. Front tube none the less. Gladly I was able to keep the bike under control without further incident and managed to call for a ride home (stupidly) I had no spare tube on me.
1) moments before the "POP" I noticed something on the front tire. The tread on my tires are blue with black sidewalls, and the extra "something wrong" was black. So either the tire pulled free of the rim or there was something black stuck in/on the sidewall.
2) tube ended up with a 2" slit on the left side of the tube, approx along side the stem. Does not appear that the root cause was the stem though.
3) new wheels, new tube, new tires. All with less than 50mi on them. Brand new rim strips, which do not appear to have moved at all.
