Espresso Doppio is an inflate and repair cartridge: it allows repair of punctures quickly, injecting a foam of Caffélatex through Presta valves. IMPORTANT: Espresso Doppio only works with Presta valves.
Quick repair in case of a puncture, no need to remove the wheel
Easy to use silicone tube that fits directly on the valve (only for Presta valves)
It doesn’t contain ammonia or other corrosive substances
Permanent repair
Quick repair
Espresso Doppio allows repair of punctures quickly, by injecting a foam of Caffélatex (synthetic latex-based sealant) through the Presta valve. This avoids the need of removing the wheel.Espresso Doppio is ideal for road, triathlon and off-road cycling, and repairs punctures in tubeless tires, tubulars and inner tubes.
Espresso Doppio contains Caffélatex liquid and propane gas: the first performs the puncture repairing action, the second inflates the tire. Caffélatex is an ammonia-free sealant, harmless for tires and rims. For this reason Espresso Doppio does not damage the inner tubes, not even the latex ones used for high-end tubulars.
Final repair
If the puncture is indeed repairable (Espresso Doppio does not repair large cuts or holes greater than 4mm) 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 tire in the following days to evaluate abnormal pressure losses. The propane contained in Espresso Doppio is not retained for a long time by a tire 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.
Maximum repairable damage in inner tubes
Inner tubes expand when inflated - limited in their volume increase by the tire 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 tire (where the shape and size of a puncture changes little with pressure) is greater than with a tire with tube. Espresso Doppio generally repairs holes up to 1mm in inner tubes, up to 4mm in a tubeless.
Dosage
Espresso Doppio is single-dose (one cartridge for one tire) and only works with Presta valves. Delivery can be interrupted and resumed at will by pressing the nozzle button.
