Effetto Mariposa

Effetto Mariposa was born in 2007 with Giustaforza, the first torque wrench specially designed for cycling. Why did we do it? Because we think that every bicycle equipped with high-end components deserves a professional maintenance, with professional tools. After more than ten years, Giustaforza is still the benchmark in the industry.

Today, Effetto Mariposa specializes in bicycle torque wrenches, accessories for tubeless tyres, visco-elastic protective films and much more. Everything is designed and developed for cycling purpose. Effetto Mariposa is located just outside Lugano, Cantone Ticino (Switzerland).
