Glue for treads for tubular tyres

cocothedog

Anybody out there who knows what glue to use to stick on a tread on a tubular tyre carcass? Tyre in question is a Dugast Silk in good condition but it has a Vittoria tread and I'd quite like to stick on a Wolber one. Any help/advice appreciated. Thanks.

Eh?

To the best of my knowledge, you cannot change the 'tread' on a tub, you need to buy a different tyre.

I suppose you would have to use whatever process or glue that is used when making tubs in the first place. I'm guessing but it could involve some sort of liquid ruber/latex, pressure or/and heat. So Dugast doesn't actually make the tread themselves, but it's bought in?

On a related topic, I'd like to know how to repair dried out sidewalls, I've got a couple of old unused tubs where the casing threads have come apart in a few places, I know that the casing threads on traditional tubs are merely held in place with rubber...

Replace with new for both issues here - nothing worse than a tyre disintegrating at 40 mph !

It is indeed latex adhesive, Gripsotex 60 is probably the best, try asking a leatherworker if he can let you have some.
Tom 753, there is a solution sold for the tyre walls, but really it's identical to Copydex.

Indeed Tom you are right about the gluing process. I've just heard back from the kind people at Dugast [with whom I've spent over £400 recently on new silk tubs]. They will re-tread my newly acquired A1 condition used Roubaix silks with the new type of treads which I prefer. I had a feeling that re-treading was possible as - until recently, if my memory serves me well - Dugast provided a service for MTB tubs wherein the buyer supplied their own treads.

There was me feeling extravagant for using Veloflex records for racing
cocothedog, I am intrigued as to whether you use these tubs for competition, or whether it's for something else? Maybe you could elaborate?

For the joy of cycling after a lifetime of work. And I can afford it. OK?

My interest is genuine - rest assured 8)
The race assumption was due to the knowledge Dugast silks were the choice of Michael Hutchinson when he attempted the hour record.

Knowing that purely the joy od cycling is your reason for using them has only made me more interested in the rest of your bike.
I would be interested to know for starters, about your rim/spoke/hub choice, as I would assume that these choices would be part and parcel of the reason why you've chosen the tubs that you have.
Any pix of your bike?
