    Frame

    Frame

    Using a 4130 frame and balanced geometry, Big Dog is our capable all-rounder ready to tackle any trail you fancy. Steel has always been the most compliant material to build frames with, keeping you fresh on the roughest of rides. Big wheels shod with 2.35 tyres maintain traction but also offer faster rolling speeds than smaller wheels. To put it simply, if your rides span from fast loops of your local singletrack to all-day epics, the Big Dog will fit the bill perfectly.
