mercurystorm Posted February 9, 2010 Posted February 9, 2010 What are the best tubes to put on my bike (700x23C)? I had a rear blowout at 45km/h on the emperors palace classic just before getting back to Carnival city (my first blowout) and im not keen on doing it again, it lost me a good 10minutes and I lost the group i was riding with, so in the end most likely cost me more then 10minutes! Also I see most road bikes use Presta valves... why? is there any harm in using Schrader valves, they are so much easier to inflate
Minion Posted February 10, 2010 Posted February 10, 2010 Without knowing the full details of what happened, I'd still suspect that whatever caused the blowout would have damaged any tube. Most inner tubes are made out of butyl (with some lightweight ones made from latex). Generally, thickness = durability = weight, so go for the heaviest tube you can find. Again, I'm guessing, but I'd say road bikes use Presta valves because the rim profile is much narrower than MTBs'. A larger, Schrader-sized, hole might be a significant structural weakpoint in the rim. Edman2010-02-10 01:46:40
techguy Posted February 10, 2010 Posted February 10, 2010 A tubes a tube, a blowout is 9 out of 10 times caused by an impact or damage to the structure of the tyre...
AndreZA Posted February 10, 2010 Posted February 10, 2010 Like techguy says, a tube is a tube. BUT I like the Michelins more because their mold lines are not as prominent as the cheaper ones.
Montblanc Posted February 10, 2010 Posted February 10, 2010 Is the Continental Race Supersonic Tube any good?
mercurystorm Posted February 10, 2010 Author Posted February 10, 2010 checked the structure of the tire when i got home, and its still in perfect condition, i think the tube was just old (put on gatorskins 300km ago, but didn't change the tubes), so new tubes this weekend it is!
techguy Posted February 10, 2010 Posted February 10, 2010 Is the Continental Race Supersonic Tube any good? Good for what? Puncturing on our roads yes...on Euro roads fine
Johan Bornman Posted February 10, 2010 Posted February 10, 2010 If you heard a bang, then it was not the tube's fault. A tube that is inside a tyre cannot make the characteristic bang noise. A loud bang is the result of the bead lifting, the tube escaping like a hernia, exploding and then withdrawing innocently back to inside the tyre as if nothing happened. It is no use checking the tyre for faults. You won't see a stretched or weak bead. It looks just like any other tyre. If you are really brave, you can simulate the explosion again. Wear some ear and eye protection and pump that tyre until the bead starts to lift. You'll easily see it. Pump a bit more and the tube starts to pop out and then...Bang! Afterwards the tube is back inside and the tyre looks fine. However, the tube will have a long cut in it. In fact, if the tube has a long cut, it happened outside the tyre, not inside. If your blowout was an explosion, you need better tyres, not better tubes.Johan Bornman2010-02-10 12:04:26
DownhillingKing Posted February 10, 2010 Posted February 10, 2010 Best Tubes Motor X tubes. . . If you can get them to fit
Eldron Posted February 11, 2010 Posted February 11, 2010 The 4 most likely causes of BANGS are: - hitting something big enough to rip a hole in your tyre- tube not seated properly (part of tube under tyre bead)- an existing hole in the tyre that the tube managed to squeeze through- rim tape old and cracked (tube explodes into rim) Like the others said - probably bad/old/damaged tyre rather than tube.
