Effetto started developing their Carogna (pronounced €œcar-own-ya€) double-adhesive tubular tape with a clear and ambitious goal: to bridge the gap between previously existing tapes and mastic in terms of gluing performance and heat-resistance, while retaining all the advantages of tapes.
In addition to this, they gave specific additional consideration to cyclocross and mountain-bike tubulars, where specific features are needed from the gluing standpoint.
Carogna is available in two sizes:
Narrow - 16.5 mm wide - suitable for rims up to 20.5mm wide
Wide - 25 mm wide - suitable for rims over 20.5mm wide
CHARACTERISTICS:
Universal performance: Carogna has been tested and is designed to perform flawlessly on any rim material (aluminium, carbon), with any tubular (seamless, handmade, vulcanized sew-ups€¦), on and off-road (cyclocross, mountain bike).
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 aluminium 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).
Wide temperature range: Once adhesion is set, the use at low temperatures (down to -40°C) is not a problem. Thermal resistance of all materials used in the manufacture of Carogna was a high priority: Carogna will provide a perfect bonding at 150°C for extended periods (hours), exceeding the heat-resistance of even the best mastics and widely exceeding the heat-resistance of any other tubular tape.
Optimized adhesive surface: Adhesion is very strong and uniform across the whole circumference of the rim for all tubulars and it is also uniform across the tubular base tape. One short-coming of tubular tape to-date has been limited adhesion at the edges of the base tape or in the centre of tubulars with a raised centre seam. Carogna solves these problems.
Optimal use: The ideal thermal range for application of Carogna is between 21°C and 38°C, allowing 8 hours to reach 80% of the adhesive strength . Applying the tape below 10°C is not recommended.
We recommend cleaning surfaces using iso-propylic alcohol.
Why €œCarogna€?
In several areas in Italy, €œCarogna€ (meaning: corpse in putrefaction) was the old name for tubular mastic, as mastic smells bad and is gooey. Carogna: a historical, funny name for a modern product that serves the same purpose of smelly old mastic. in a clean, fast and odourless way!!
