Carogna double sided adhesive tape for tubulars bridges the gap between previously existing tapes and mastic in terms of gluing performance and heat-resistance.
We started developing Carogna (pronounced “car-own-ya”) double sided 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, we gave specific additional consideration to cyclocross (read the specific how-to guide here!) and mountain-bike tubulars, where specific features are needed from the gluing standpoint.
Carogna has been tested and is designed to perform flawlessly on any rim material (aluminum, carbon), with any tubular (seamless, handmade, vulcanized sew-ups…), on and off-road.
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).
Wide temperature range in use:
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 center of tubulars with a raised center seam. Carogna solves these problems.
Temperature range when mounting :
The ideal thermal range for application of Carogna is between 21°C and 38°C (70 to 100°F), allowing 8 hours to reach 80% of the adhesive strength . Applying the tape below 10°C is not recommended.
We recommend cleaning surfaces (rim and tubular base tape) using iso-propylic alcool or mineral spirits.
extremely easy to use compared to mastic
very reliable adhesion, in any condition
once removed, Carogna leaves the rim ready for the next gluing, without additional cleaning
works for road and cyclocross
also available in very convenient Shop rolls
Carogna is available in:
“S” (16,5 mm wide)
“SM” (20 mm wide)
“M” (25 mm wide) versions, one-wheel (2 m) rolls.
Shop size rolls of 16 m (for 8 wheels) are available.
“S” is recommended for traditional/legacy tubular rims (external width up to 20 mm), “SM” for rims with external width between 21 and 24 mm, while “M” is recommended for rims with a width between 25 and 28 mm.
In several areas in Italy, “Carogna” (meaning: carrion, 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 odorless way!!
The big question: does it work for cyclocross?
Carogna tape works for cyclocross, we’ve had in general very positive feed-back. Journalists and early adopters like Lennard Zinn of Velonews and Mike Yozell of Bicycling confirm Carogna indeed works for cx.
However, not surprisingly, it turns out that knowing the correct gluing procedure is much more important for cx than for normal road use: similarly to mastic, an average gluing job won’t survive cyclocross applications.
Carogna glue is ‘pressure-activated’, so it bonds very strongly when it’s pushed down against the rim by the tubular pressure (for this reason, for road tubulars, we recommend inflating tubulars to their max pressure and allowing some time before riding: adhesion reaches 80% of its maximum strength after 8 hours, the optimal value of 99% after 24 hours).
Important remarks for cyclocross use of Carogna:
AVOID SANDPAPER ON THE RIM
we know this is common practice when gluing with mastic, but tapes are different. Sandpaper will create small grooves on the rim, reducing the effective bonding surface for the tape. A smooth rim bed offers the maximum surface of contact for Carogna: we recommend removing eventual residual glue completely with Carogna Remover before applying Carogna tape.
CAROGNA WIDTH MUST BE THE CORRECT ONE FOR YOUR RIM
if Carogna tape is much wider than your rims (for example Carogna “M”, 25mm, on a 20mm rim) there is tape on the side that isn’t properly glued to the tubular/rim (just because the rim didn’t extend wide enough and the tape couldn’t be “sandwiched” between tubular and rim). That area is a potential entry point from where dirt and mud could get underneath the glued section of Carogna… not immediately, but within your third or fourth weekend of races. It’s better to trim the eventual excess with a cutter, before mounting the tubular (Lennard Zinn shows how in the video below).
DON’T LET YOUR TUBULARS OUT TO FREEZE BEFORE THEY ‘STICK’
as written in the mounting instructions, the ideal thermal range for application of Carogna is between 21°C and 38°C (70 to 100°F), allowing 8 hours to reach 80% of the adhesive strenght . Applying the tape below 10°C is not recommended. If it’s too cold the glue won’t be able to develop permanent bonds, as it’s supposed to do. Once adhesion is set, the use at low temperatures (down to -40°C) is not a problem.
LOWER INFLATING PRESSURE MIGHT REQUIRE LONGER GLUING TIME
as most cx tubulars won’t allow a very high maximum pressure, Carogna might require a longer time before optimal adhesion. This depends very much on the finishing/surface of the tubular base tape.
In most cases, this is not needed, but we’ve been reported cases where cyclocross tubulars were not glued after 8 hours… but were perfectly glued allowing one more day at maximum pressure.
