As a devout tubular devotee for over 34 years (ever since my original Paramount came with DelMundos) I have used cement and hgave come upwith my own methods of stretching, affixing, and caring for the tubs. Even though I'd been a race inspector for years, DQ-ing many a roller-to-be, I once punctured 10 minutes before a squirrely circuit race in Ottawa. I did an emergency tubendectomy. I smeared a thincoat of cement on the previously-glued rim and a thincoad on a barely-aged tub. The old Dodge wagon had been sitting in the sun for hours near the start, so I used the 140 degree backseat oven to bake both, and minuted before the gun, i smacked them together like a contact cement job. Ordinarily I usually apply a wetcoat to the rim, letting it desolve the hardened glue from the previous applications. After tacky, another wetcoat and ease on the barely-inflated tub., inflate a bit more and center.

At the recent Interbike roller race, I made a deal with Conti for some way light Sonderklasses and had no cement. With rcrank RPM's in the 200 range, the wheels would be going 1200 RPM and nobody wants a separation in front of a crowd, nor do any spectators appreciate mastice gutta in their locks or duds. So, the fine folk at Tufo were kind enough to retailme a couple of wads of their tubular tape. I installed it the obvious way,peeling it away from the release tape and sticking it to the rim, then pressing it into the rim. After that, the release tape was removed and the partially-inflated tub to the taped rim.

Because the tapeis really tacky, unlike the gooier cement, the tub must be 'lifted and placed' onto the tape and cannot be 'eased' onto the rim bed from the side.

The Contis were tight and hed to be lifted and placed a few more times. Later, when I went by the Tufo booth to let them know we made it all happen in time, I learned embarassinglt that I put the wrong side to the rim. Apparently, I should have applied the top, stickier side to the rim and the 'gooier' side to the tire, allowing some of this placement adjustment.

We have the tape in stock and it's somewhere about $5, but your local shop might have it too.
