Effetto Mariposa’s Carogna Tubular Tape


Despite all of the niggles associated with tubular tires, their unmatched ride quality and performance, continues to prevail. 

In an effort to simplify the mounting process, Effete Mariposa has essentially eliminated the painstaking steps of gluing tubulars to the rim, with a new doubled sided adhesive tape – called Carogna. 

While Carogna is far from being the first tubular adhesive tape, Tufo has offered a similar product for years, it’s the first to adhere the edges of the tire to the rim, thus securing it it across the entire width of the rim.

According to Effetto Mariposa founder Alberto De Gioannini, this makes for a more secure bond.

“Tufo tape is thicker in the center and thinner on the sides, and it’s quite stiff.” “It only relies on the adhesive to keep the tubular there. My concept is different. On the rim side is a semi-structural glue that bonds to the rim surface. It’s very hard to remove – but you can remove it, and the glue will stay with the tape.”

“On the tubular side, there is a 1mm thick mass of glue that has been developed for underwater applications. When you inflate the tubular, the glue squeezes so it provides an optimal adhesive surface covering. It gets to 90 percent of its maximum adhesion after eight hours.”

In addition, De Gioannini says the Carogna tape provides a more even bond layer around the entire circumference of the rim than traditionally hand-applied adhesive, since the tape is the same thickness throughout. Moreover, Carogna will peel off the rim almost perfectly, leaving a clean surface behind that’s ready to have another tire mounted almost immediately. 

“On the tubular side, the glue is permanent so you won’t be able to remove the glue from the tire. Part of the glue will stay on it but you can remove it and you will end up with a thin layer of glue. So it’s similar to what you get with mastic but it’s even.”

De Gioannini also says that Carogna will retain its adhesive strength in excessive of 300 degrees fahrenheit, as compared to other gluing methods that can begin to deteriorate quicker, at lower temperatures.




We started developing our Carogna (pronounced “car-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, we gave specific additional consideration to cyclocross and mountain-bike tubulars, where specific features are needed from the gluing standpoint.


Universal performance: 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 (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 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: 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.

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 strenght . Applying the tape below 10°C is not recommended.

We recommend cleaning surfaces using iso-propylic alcohol.

Available sizes: Carogna is available in “S” (16,5 mm wide) and “M” (25 mm wide) versions, one-wheel (2 m) rolls. Shop size rolls of 16 m (for 8 wheels) are available in both “S” and “M” widths.

Rim width: “S” is recommended for traditional tubular rims (gluing channel width up to 20,5 mm), “M” is best for rims with gluing channels over 21 mm of width.

Why “Carogna”?
In several areas in Italy, “Carogna” 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!!
