Project goalsMy goal in developing the Puffin is to create a fatbike which excels not only in the kind of soft conditions for which the oversize 26x4.0" tyres were designed - but to provide a lively and fun bike for general trail riding. Achieving this has meant taking much of what I have learnt in designing the vaunted 29er Swift, and applying those same principles to a fatbike. Sharp handling, a lively feel and perfect balance were high on the agenda. That said, it was not simply a matter of taking the same geometry and tubing and giving it enough clearance for the big tyres. There are many changes from the Swift both in tubing choice and geometry.
