While Effetto Mariposa’s Espresso quick fill canister’s 75ml shot of Caffélatex sealant will put a punctured road or ‘cross bike tire back into action, it may not be enough for larger volume mountain bike treads.

For that, there’s the new 125ml Espresso Doppio. The can combines sealant and a propellant to both fill and seal 27.5″, 29er and 29+ tires in one shot.
