Too many flats... here's one solution.
I have been having an inordinate number of flats from thorns and glass on my 29'er. As I was fixing one today I remembered a little gizmo that I used to have on my road bike. The thing was called a tire saver, and it was basically a wire that rubbed gently on the tire. It would knock the stuff out of the tire before it had a chance to do any harm. I made one for my 29'er, and I'm sure it will save me from patching so many flats in the future. Unfortunately it won't work on anything knobby, just smoothish road tires. I used a wire coat hanger, and made a yoke that attaches with my brake bolt. Two small pieces of plastic tubing connect the yoke to the wire that rubs the tire (another piece of coat hanger). I bent the wire on the tire to the profile of my tire, and the light pressure from the plastic tubing is all that holds it against the tire. I may make it a little narrower so that it can go under the fork crown and be tucked out of the way, but for now it should work nicely.

Cool. I take my old tubes, cut them down the middle and put one or two around my current tube. I NEVER get flats. -- Goats_On_Unicycles -So hot!

Tubeless would be interesting. I have thought about it, but I have to find out more about it. From what I understand it is heavier than a tube in most cases, but offers a liveliness like a sew-up. If I could get that road feel it would certainly be worth any moderate weight gain. -- jtrops ------------------------------------------------------------------------ jtrops's Profile: http://www.unicyclist.com/profile/17262 View this thread: http://www.unicyclist.com/thread/75435 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- http://www.usenet.com |

Looks like youre running the Schwalbe Marathon tire. Next time you change it, get the Schwalbe Marathon Plus. It got a gel compund inside that protects the tube from sharp edges and stuff. -- Smilymarco 'Municycle.com' (http://www.municycle.com) Lesen - Denken - Posten ------------------------------------------------------------------------ Smilymarco's Profile: http://www.unicyclist.com/profile/4110 View this thread: http://www.unicyclist.com/thread/75435 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- http://www.usenet.com |

Have a read of 'this' (http://www.gsportbmx.com/tech/punctures.php). Not sure how much would translate from bmx but must be worth a go.

Too many flats... here's one solution.
the tire is a big apple 29x2.35. After working in a bike shop for 9 years I have seen many different kinds of flats, and these ones are plain old stuff getting through the tread. The bulk of my flats are goat heads. The Big Apple is supposed to have a kevlar belt in it to prevent flats. My thought is that if it is working at all I must be riding on the worst section of road ever. Thanks for all of the advice about flats. I will look into going tubeless. I was posting this idea for the benefit of anyone else with a road uni, and puncture problems. It's simple, cheap, fast, light, and it works well at what it does. -- jtrops ------------------------------------------------------------------------ jtrops's Profile: http://www.unicyclist.com/profile/17262 View this thread: http://www.unicyclist.com/thread/75435 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- http://www.usenet.com |

Looks a lot more useful than the ones that I made for my bike a couple of years ago. I hope it works for you - mine were hopeless. I tried to buy a pair, but no-one seems to sell them these days. From most of what I've read, that seems to be largely because they're not particularly effective. -- Danny Colyer 'http://www.redpedals.co.uk' (http://www.colyer.plus.com/danny/) "I don't think proofreading is adequate.

It got a gel compund inside that protects the tube from sharp edges and stuff. The OP mentioned that he didn't want a heavy tyre. I'm running Marathon Pluses on my bike. The 20" on the front has been on for 18 months without a puncture, and I really don't notice the extra weight and rolling resistance over a standard Marathon or the Marathon Slick that I was using before. I'm very, very pleased with it. The 26" on the back is a different matter, though - with the bigger wheel I notice the increased rotating weight. I'll replace the 20" M+ with the same, but I'll probably try the Marathon Supreme for my next 26" tyre. With a 29" tyre, I'd expect the weight of the M+ to be *really* noticeable. -- Danny Colyer 'http://www.redpedals.co.uk' (http://www.colyer.plus.com/danny/) "I don't think proofreading is adequate.

I think a major part of the problem is the broken glass issue which we face in many places in the world. We have the worst section of road ever here too- and it's everywhere. When I used to ride my 28" to Bell Block every day, some weeks I had up to 5 punctures. We need effective systems at stopping people from breaking glass on the roads, or to find an alternative to glass! If anyone has any creative ideas about glass management please share them. Many good ideas are being ignored by our regional council and local government when we suggest things like a refund on bottles (most people won't smash a bottle that cost them $2 extra). But I don't think tying glass to money would fix it either because the most evil people have the most money, and would not care about small change. Changing to a 36" reduced my punctures from heaps to almost zero. Most of my tire problems have been caused by faulty manufacturing on the 36" innertubes, with two of them splitting at the seams untouched by glass. I've still got a slow leak caused by this defect. At 5 times the cost of a regular innertube there is really no excuse for such a consistently faulty product (two out of three tubes had the same fault). -- Rowan ------------------------------------------------------------------------ Rowan's Profile: http://www.unicyclist.com/profile/3772 View this thread: http://www.unicyclist.com/thread/75435 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- http://www.usenet.com |
