Espresso Doppio - Inflate and repair cartridgeRegular price 17.50 CHF
Espresso Doppio is an inflate and repair cartridge: it allows cyclists to repair punctures quickly, injecting a foam of Caffélatex through Presta valves.
Ideal for Enduro and for wide section tyres (up to “29+").
**Espresso Doppio 125 ml is a spray product: we sell it directly from our e-shop only in Switzerland and Italy (but you can buy it in your Country, ask email@example.com if you can't find it!)**
- Quick repair in case of puncture, no need to remove the wheel
- Easy to use thanks to the silicone tube that fits directly on the valve (only for Presta valves)
- Ideal for Enduro and for wide section tyres (up to “29+”)
- It doesn’t contain ammonia or other corrosive substances
- Permanent repair
Why we created it
While Espresso (75 ml) remains the ideal solution for road or cross-country, cyclists who prefer wider section (such as Enduro racers) up to “Plus” tyres will appreciate the additional inflation and repair power guaranteed by the 125 ml Espresso Doppio .
Espresso Doppio allows cyclists to repair punctures quickly, by injecting a foam of Caffélatex (synthetic latex-based sealant) through the Presta valve. This avoids the need of removing the wheel, saving precious time: just over a minute is enough to inflate and repair tyres up to size "29+", returning immediately to pedaling.
Easy to use
In case of puncture the stress level is high, and Espresso Doppio is designed to work simply and effectively, eliminating possible problems.
For example, we have eliminated the common threaded adapter (in plastic or brass) between the tube of the canister and the valve - a potential point of leakage of foam, if not threaded in correctly - by switching to a flexible silicone tube. This tube is unique in its kind and fits directly onto the Presta valve, so that the special repairing foam (based on Caffélatex) penetrates directly into the tyre, without leaks.
In the case of wheels with spokes close to the valve, the silicone tube allows the use of Espresso Doppio despite the limited space available (in these cases cartridges with direct connection are unusable).
IMPORTANT: Espresso Doppio only works with Presta valve.
Espresso Doppio is ideal for road, triathlon and off-road cycling, and repairs punctures in tubeless tyres, tubulars and inner tubes.
Espresso Doppio contains Caffélatex liquid and propane gas: the first performs the puncture repairing action, the second inflates the tyre. Caffélatex is an ammonia-free sealant, harmless for tyres and rims. For this reason Espresso Doppio does not damage the inner tubes, not even the latex ones used for high-end tubulars.
IMPORTANT: if the Caffélatex sealant is already present inside the tyre, Espresso Doppio can still be used to facilitate the repair of the puncture and increase the inflation pressure.
If the puncture is indeed repairable (Espresso Doppio does not repair large cuts or holes greater than 4 mm) the synthetic latex contained in the canister closes the hole in a stable manner. After using Espresso Doppio to repair a puncture, it is best to observe the tyre in the following days to evaluate abnormal pressure losses. The propane contained in Espresso Doppio is not retained for a long time by a tyre or inner tube, so a pressure loss is normal within 24 hours after using Espresso Doppio ... easily remedied by inflating with a normal pump. If after this the pressure becomes stable, the repair is final and there’s no need to do anything else, just pedal!
Maximum repairable damage in inner tubes
Inner tubes expand when inflated - limited in their volume increase by the tyre alone - and a hole in an inner tube tends to change geometry and size at different pressures. Since a hole in an inner tube expands with inflation, the maximum damage that can be repaired in a tubeless tyre (where the shape and size of a puncture changes little with pressure) is greater than with a tyre with tube. Espresso Doppio generally repairs holes up to 1 mm in inner tubes, up to 4 times larger in a tubeless.
Espresso Doppio is single-dose (one cartridge for one tyre) and only works with Presta valves. Delivery can be interrupted and resumed at will by pressing the nozzle button.
Espresso Doppio can inflate a 29x2.40 (62-622) tyre at about 2 bar, it reaches about 1 bar with 29x3.20 tyres (80-622). It is possible to further inflate the tyre after using Espresso Doppio.
