Hi,

It might be caused by the rim cement "working" (as in trying to adhere but having to let go at each revolution) but that would not make that kind of sound IME.

However, a Veloflex Carbon or any Veloflex tyre for that matter should not present a bulge around the valve area.
Maybe the tyre wasn't properly put on as in not pulled sideways enough as it was put on the rim?

Just guessing but that's what I suspect.

Maybe wiser minds than mine will come to rescue.....

Ciao, ;)

if you take the wheel out, put it in a stand or hold it, then spin it, does it still 'tick'?

After reading this topic and some other tubular repair topics on internet I openend the tubular for about 10cm of the valvehole, replaced the inner tube with a new latex inner tube (Vredestein), sewed it up again. Checked it and at last I glued the basetape back into place and put the tubular on a spare rim.

I inflated it up to 10 bar and it is holding with no bumps etc.

I only repaired a flat tubular once before so I do not have a lot of experience. But take your time, work carefully and do not hurry and you will succeed. Most member of the cycling club call me crazy for using tubulars. I agree that it takes more time compared to clinchers but it is no rocket science and I simply like the ride :)

By the way, I use Bison Kit as glue for the basetap which is, as far as I know, the same as Barge Cement.

If you have question about replacing an inner tube please let me know. Next time I will take pictures.

I'm sure I have described the procedure a few times already, just don't seem to find it somehow.

Anyhow, here's the link mentioned by jekyll man:

I just took a tub off it's rim after more than 4500 km's of work :beerchug: ...

I'm wondering (it's been probably discussed already somewhere in here, but I can't find it), anybody used the tubular latex tube in a clincher ?

Thanks for the info,

Louis :)

I am confusing to compare the TireAlert use latex tubes and not able to make a decision about it. How is it possible to check it?

I think what you're asking is whether Ron at TireAlert will use latex tubes or not. The answer is: yes. If you provide him the tubes, he will use them. He still will not take responsibility (rightly) for the size. One of the guys on this Board just got tubulars back from Ron and he used latex Vittoria clincher tubes. No problems.

Hi,

AFAIK Ron uses butyl inner tubes per definition. If you want him to use the inner tube of your choice you simply send it along with the tubbie to repair and he'll then use that.
No idea if he'd charge extra bucks or whatever but it can be done.

Ciao and greetings to Geoff, ;)

The Vittoria latex tubular inner tube is 42 g, opposed to a Vittoria clincher latex tube at 70 g :shock: .
Feels waaaayyy thinner too. I'll have to be careful that the rim bed and inner side of the tire are impeccable with this tube...

Louis, that is 100% correct. They are also smaller. Unfortunately, latex tubes for tubular tires are hard to come by, which is why Ron doesn't 'stock' them.

I put them inside a 23mm open tubular. Doesn't hold air for very long. After one hour, it already lost 50 PSI. Too stretched I guess...
Probably would be better to put them inside some 20mm tires.
