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 in the Peaks, the Big Dog will fit the bill perfectly.

Frame comes with: hanger and axle

Sizing Notes

All frame size recommendations are approximate. A good fit will also depend on the correct choice of stem length, correct bike set-up for the rider and riding style.

Correct frame size choice can vary greatly with riders' torso length. If you have longer legs and a shorter torso, go for a slightly shorter stem. If you think you are borderline between sizes, and you have longer legs and a shorter torso, go for the smaller frame size. If you have shorter legs and a longer torso, go for the larger frame size to get the extra top tube length.

As the frame sizes increase, so does the length of the head tube. If you are inflexible or perhaps have a history of back problems, consider going for a larger frame size. This will increase the relative height of the handlebars making the position less “extreme”. The larger frame will also have a longer top tube, so you’ll need to compensate for this with a shorter stem.
