Based around a twin top tube frame design, giving optimal material placement and futureproofed mounting points for a high volume frame bag, Fatty features progressive trail worthy geometry optimised for use in true “all terrain” conditions.
We designed the huge On-One Floater 4.0in tyre on 70mm rims to give superb floatation and tracking over a huge range of surfaces, allowing traction where any other tyre would be left bogged down and spinning. Run a 6-15psi they offer an incredible amount of shock absorption, tuneable with the psi used, to give optimal conditions. If in doubt, let air out! The wheels run on our own model Fat hubs, CNC’d from solid 6061 billet aluminium with a 135mm axle spacing up front, and a 170mm rear. Putting the chainline perfectly positioned for tyre clearance on the 100mm wide BB shell. It’s all designed to give a great ride without you having to worry about fixing parts up yourself.
Our 5pc welded fork allows us to control ride quality of the rigid fork, and also equip Fatty with the best handling we’ve found around. A long 55mm fork offset dials the 69deg head angle perfectly in to trail riding up and down, with a light touch when you need it and stability when things get bouncy. Futureproofed with a 470mm fork length, we’re ready for the fat front suspension revolution too.
Build on this model is from SRAM with their X5 10spd group giving 1×10 efficiency and a good low climber gear. The Holzfeller crankset shrugs of everything you can throw at it, spinning on a BB that’s SRAM rated for toughness.
Other finishing kit comes from our proven supplies, new and old. Seatpost size is 31.6mm, an On-One Hotbox stem clamps an El Guapo Ancho B bar, with On-One Bob on grips. Headtube size is Smoothie Mixer standard, so will work with our Slacksets to adjust steering feel further.
Why get Fat? Why not?! It’s a totally new experience, trail capable and fun fun fun. As recently as last week, our chief tester Jon “Shaggy” Ross, rode the whole of the gruelling Trans Provence race route on his proto Fatty, solidly putting this genre on the map for trail capable handling. Four inches of bouncy rubber might be a world away from 150mm full suspension bikes, but it’s like compared cheese and chocolate. Fat is good. Get Fat. Get Fatty.
Production bikes will feature undrilled rims.
