CHARACTERISTICS:
Why we created it:
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.
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.
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.
See the instruction
leaflet for detailed mounting instructions.
Why "Carogna"?
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.
SURFACES MIGHT BE
PROPERLY CLEANED/PREPARED
Especially when using tubulars with a raw cotton/unprotected base tape, extra
care should be taken to clean the gluing surfaces. We recommend our Eau de
Carogna gluing primer for the tubular base tape, to make sure adhesion is not
hindered by dust or humidity.
The quality of the adhesion should be checked by completely deflating the
tubular and gently pushing it on the side. If the tubular is still not holding,
waiting longer will normally address the issue.
