From backcountry bike-pack trips to full on mountain bike trails, the Mostro can be configured to meet your off-road dreams. It can be built to clear up to a 700x55c tire, and with the new Enve Adventure fork, it can be outfitted with any number of pannier and rack configurations. While it checks all the boxes for sheer utility, the Prova Mostro doesn't make any sacrifices on form. With its 3D printed dropouts and chainstay yoke, beautifully curved stays and seat tube, and immaculate tig welds, it holds up the the standards of what makes a Prova a Prova. Where would you go with a Prova Mostro?
