Advanced tubular question
Quote | Reply
I have a Michelin tubular that wore out the tube way before the tire. The tube had holes each place the thread passed through the casing so there were lots of pin holes in a zigzag pattern. I took the tube out completely and want to sew in a new one. The thread is now in a zillion pieces. I have a naked casing in very good condition and want to make it into a tire again.

1) Which tube would YOU use and why.

2) Which thread would YOU use and why.

1. You will need a tubular specific tube. The best place for a spare tube is another tubular.

2. Use the thread that comes with a tubular repair kit. Always resuse the existing holes in the casing.

This is how people fixed flats for a long time before high-pressure clinchers came into being. It's neighter cheap nor stupid. Repairing a flat tubular is a dead art. This is the perfect time of year to learn. I'm sure some of your rich, smart friends will have a worn tubular that they'll give you. Carefully remove the tube and put it in the old casing.

There should be a thin fabric strip inside the tire between the stitched area and the tube. If that wasn't there it's no wonder there was a problem.

waxed dental-floss has always worked great in patching tubies.... re-use the stitch holes and with the same threading pattern.

Ok, I know there was supposed to be a strip of fabric in there. But this tire does not, did not. Do not know if the others of the same make do or not. I think not. Given that fact:

3) Which way would you install the cloth strip, of what material, how thick, and how wide?

I like the tire because it has the same grip that the Michelin ProRace clinchers have. Besides why not fix it? I have the wheels. I figure it will take the same effort to fix as to get a new tire. Besides I like it. OOOPPPS I said that already.

ORNERY Dan. No perhaps just grumpy but getting better since am getting this tire fixed soon.

Thanks

Hi Dan,

I have done this on more than one occasion. It's kind of fun.

A tube is a tube - kind of. just decide if you want to use latex or butyl, and what size you need, and buy one at your LBS, a standard clincher style tube.

Tubies do vary quite a bit in tube size, so just taking a tube out of another tubie, different brand, different size, is less likely to get you the right size tube than matching the one you have with a new one at the shop. Size is the only thing that matters, and really, it doesn't matter much.

Use a strip of cotton seam tape to cover the sewn casing. Go to a sewing supply shop or a tailor, tell tham what you are trying to do, and they can hook you up. Glue the tape on with tire life or liquid latex.

Dental floss will work fine to re-sew, or take a sample thread from your tire remnants to that same sewing supply house. Make sure to glue down the bitter end of the thread with the tire life/L latex.

Thanks for the confirmation. I actually went to the LBS yesterday bought a butyl tube would use for my clinchers if not for this project. So if use butyl tube can I leave out the chaff strip inside the tire that protects the soft latex tube from the stitching?

Trisanta

Perhaps I can get away without the old tubular/tube.????

The butyl tube will work just fine, but you still need the strip. Don't bother with the tube from th other tubie.

So since this tubular never had a strip and that may be the reason wore out the tube and they do not sell them anymore,,,, there is nothing to copy

4) What kind of material would work for a chaff strip?
