Carogna is available in 3 widths, and each width is available in two sizes - 2m roll (enough for 1 wheel) and 16 m "shop roll" (enough for 8 wheels).
Specific adhesive properties on rim and tubular: the tape has two application-specific sides:
- Semi-structural and removable on the rim-side: adhesion is guaranteed by industrial-grade acrylic glue, native to the base tape; this means that when removing the tubular (breaking its bond with the rim), the acrylic glue will stay on the tape, not on the rim. Acrylic has a good adhesion on both aluminum and carbon without any specific surface preparation.
- Permanent on the tubular side: there s a 1 mm-thick layer of a recently-developed permanent glue for underwater applications. This thick glue film will move and spread when the tubular is first inflated, ensuring optimized contact with any tubular base tape geometry. Humidity is obviously not an issue, and this glue adheres well to any kind of base tape material (nylon, cotton, poly-cotton) or external finishing (raw, brushed, or coated by neoprene).

1. Clean gluing surfaces, both on the rim and the tubular, with isopropyl alcohol (or other dry, fully evaporating degreaser) and let dry. Then pass a clean, dry cloth over the rim.
2. Starting just over the valve hole, apply Carogna onto the rim without removing the orange protective liner. Keep Carogna slightly tensioned, so that it sticks to the rim channel on its whole width, for the complete rim circumference. Stop immediately before the valve hole, cutting away the excess tape.
3. Peel off the orange liner for 2 inches on both Carogna ends and fold to the side.
4. Fully deflate the tubular, then mount it on the rim inserting the valve in the valve hole first. The orange liner ends should be accessible on the side when the tubular was mounted.
5. Once mounted, inflate the tubular to around 60 psi (30 psi for cyclocross and mtb tubulars) and adjust its position, centering it on the rim.
6. After the tubular is properly centered, without deflating, pull one loose end of the orange liner perpendicular to the tubular until you completely remove it from the whole rim circumference.
7. Inflate the tubular to its maximum pressure so that the glue is fully activated. Adhesion reaches 80% of its maximum strength after 8 hours, and the optimum value of 99% after 24 hours.
