Who's Had a 29" Tube Blowout When in a Coker Wheel?
Hey Eric, I rode a 29er tube for quite a long time, when I get home I will probably be installing one again as well. I found them very very reliable and installed two by myself without much issue, then when I went to Uninam, I tried installing one there and I got a flat so I stuck to the 36er tube. The 36er tube will definitely be more reliable, but the 29er tube is great once you have it installed properly, but you will never know if its in properly until it pops, so it's always a gamble. -- ntappin 'how to build a strong comfy saddle from junk.'

Who's Had a 29" Tube Blowout When in a Coker Wheel?
I ride 29er tubes exclusively in my 36. Not only is the weight difference quite noticable, but 29er tubes are $3.99 at performance bike. I've probably trashed four 29er tubes in my life, but now I get them in cleanly every time. My first few, I talc'd as was mentioned above, but if you get it in with a bit of air in it (so it stays round instead of flattening out around the rim, sneaking under your tire beads), and massage it with your hands until you think that it's pretty close to evenly stretched all the way around, it should work just fine. That said, I have had three blowouts of my Nightrider ti one at 65 PSI, one at 60, and one at 50. I think it's a problem with the tire, though, and not a consequence of my having used a smaller tube. A 36" tube pushes out on the tire just as much as a 29" tube does, so I don't see why one tube would cause the tire to have a better chance of blowing off the rim. I could imagine a 29er tube popping inside of the tire, without the bead coming off the rim's clincher, but ... that just doesn't really happen. I've never heard of it, and it's never happened to me. The only issue with running 29er tubes is that if you DO get a legitimate flat, you can't patch the tube. For that reason, I always bring a 36er tube with me as a spare, along with 10-12 patches, so if I get MORE flats, I can patch the 36" tube. It'd be better for me to carry one more 29er tube, so I can still ride a 29" tube after my first flat, but honestly, my only flats have been pinch-flats from me putting the tire on dumbly, or blowouts of my tire (3). I've never flatted from riding. I think it took Sam Wakeling something on the e order of 5,000 miles to get his first, true, conventional flat tire from something on the road. My advice (take it or leave it ) is to go a 29er tube. Lighter, CHEAPER, and your tire is so flat-proof anyway that chances are you'll never have to replace it if you get it in right. And if you run 29er tubes, you'll learn how to get it in without popping it -- chuckaeronut Uni to work, work to eat, eat to live, live to uni. ------------------------------------------------------------------------ chuckaeronut's Profile: http://www.unicyclist.com/profile/14677 View this thread: http://www.unicyclist.com/thread/71490 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- http://www.usenet.com |

So that's why there was a flat tube in your wheel bag.... Anyway, for several reasons I'm going to wait until I get back from France to do this conversion. I'm also toying with the idea of a tubeless coker depending on the cost. It seems far more reliable, but it's also costs more than 3.99 . Cost isn't an issue at the moment since I won an extra 36 tube at RTL (most breakdowns and most injuries went to team North American Youth) -- Eroick --Eric Evenchick Email/MSN: ------------------------------------------------------------------------ Eroick's Profile: http://www.unicyclist.com/profile/10884 View this thread: http://www.unicyclist.com/thread/71490 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- http://www.usenet.com |

Are you guys using the regular cheap 29er tubes or the thicker thorn resistant muni 29er tubes? -- Daytripper63 The Dictionary is the only place where "Success" comes before "Working" ------------------------------------------------------------------------ Daytripper63's Profile: http://www.unicyclist.com/profile/10789 View this thread: http://www.unicyclist.com/thread/71490 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- http://www.usenet.com |

Who's Had a 29" Tube Blowout When in a Coker Wheel?
I've had a 29'er tube in my dave stockton wheel for probably two years now, and I really notice the difference between it and my 36 tube in my rtl nightrider. I'm actually going to go pick up a 29'er tube and follow scott's excellent instructions for installing them. I did try to fit a schwalbe tube in my nighrider, but it was old and I wasn't particularly careful, so I had a blowout during a long ride, which kind of sucked. I'll be nicer to the wheel this time around. -- flyer ------------------------------------------------------------------------ flyer's Profile: http://www.unicyclist.com/profile/9894 View this thread: http://www.unicyclist.com/thread/71490 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- http://www.usenet.com |

I'll be nicer to the wheel this time around. Yes, I should have mentioned DO NOT USE OLD TUBES! I don't know what a safe age is, but if you have had some sitting around for a year, throw them away. When you take a tube out of the box immediately look for ANY signs of surface cracks in the rubber on the edges of the folds. The pre-stretch inflation serves the double purpose of testing for bad rubber. And yes Daytripper, use the standard-weight tubes. The heavy ones would be closer to the weight of the 36" tubes, and would have more trouble stretching to the larger size I think. Also let me stress the part about filling the tire SLOWLY (if you are using compressed air). If there is an air pocket trapped between the tire and tube and you fill rapidly, the tube can potentially overstretch and burst in that area.
