A common questions we get is what’s the difference between the #SILCA Gravelero and Tattico? They look similar, while true, the Gravelero pushes about 35% more air, which is great for filling larger volume tires quicker. The Tattico though can reach up to 100psi vs 80psi on the Gravelero. Some people who live in the Pacific Northwest do prefer the Tattico because of the increased grip of the knurled finish in wet weather.
