I ended up with a sidewall puncture on my nearly new Vittoria Corsa X-Factors during a TT this weekend. I think it was some rough pave. I tried sealing it with Pitstop and Stan's, but no luck. Based on the photo, do you think this tire is repairable? I've used Tirealert.com for tread based punctures before, but never a sidewall. On the positive side, this was my first tubular puncture during a race in over 8 years...:) Thanks for the help!

Well, it is a bit tough to say from that pic, but it looks like the sidewall damage may be a bit more than just a 'scuff' and is through some of the casing itself (the casing is comprised of bias-cut, unidirectional 'sheets'). You can sometimes repair sidewall damage using AquaSeal, or other urethane-based sealant. You may be able to save the tire, but without being able to see how 'deep' that damage is, only you will be able to judge that.

The puncture tiself sounds like a pinch-flat, which can happen with tubulars, especially with the new deep rim beds. That is certainly repairable.

Good luck!

OK. :cry:

I need some pictures of the right type of stitches to obtain a decent repair/regular shape on the tub...

The previous "typewriter caracters" explanation didn't do it for me... :oops:

for the XXXXXXXXX pattern, there're some good pictures of it in this thread...

http://www.lfgss.com/thread92080.html

(though some people use a //////// pattern)

i've always used XXXXXXX, when you sew it, use the existing holes and make sure you pull the thread tight on each stitch

after gluing back the base tape, stick it on a rim and inflate to maximum pressure, the shape of the repaired area should be indistinguishable

btw find using a light coloured thread makes it easier to see what's going on when sewing, i got a reel of white 30lb dacron backing line from an angling supplier, cheap and works well

Thanks for the link sungod :).

I'll try to do a better job on the next one, so the repaired area doesn't look like a twisted gut... :oops:

Louis-
I just do a length of \ \ \ \ \ \ \ \ into the end of the original sewing, and then back the opposite way / / / / / / / /

Finishes off a reasonable XXXXXXXXXXX :thumbup:

I picked up a new bike in the fall that came with a set of HED 3c tubular wheels in 650c with Conti Sprinter tubes glued on. As I've never owned tubular wheels I figured I would re-glue them so I would know they were done correct. The tires look brand new with next to no wear.

My problem is with the base tape. It is coming off around the whole circumference of one of the tires. I need to re-glue it but I'm having a hard time finding the appropriate glue. Maybe for the $15 or so I'm better off letting tire alert do the repair? Are they still in business? Pricing on the website is as of 2012.....

If not, what to use? Any kind of contact cement? Dap? I can't find Barge anywhere. I'm in the flooring business and I have a warehouse filled with various glues. Carpet, contact, urethane, you name it. I would just like to get it right.

Thanks.

Steve

TireAlert was in business as of a few months ago, at least. They did a nice repair job on one of my tubulars.
