On One launches a fat bike


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.

Available exclusively as a complete bike, in very limited quantities in early December.

Dream Fat Bike by Carver

Carver Ti FAT BIKE


New for 2012, Carver’s original Ti Fat Bike gets a redesign and becomes … The O’Beast. The biggest (pun intended) adjustment to the Carver Bikes O’Beast frame comes in the form of extra tire clearance adding ample room for the large 4.7″ Fat Bike tires. For 2012 Carver opted to spec the O’Beast with a versatile 44mm head tube allowing riders to run 1-1/8 or 1.5 inch tapered forks. Other new features include a replaceable derailleur hanger / dropout and a nice brake bridge at the disc caliper mount for added stopping power. The 2012 O’Beast comes in a brushed (polished) finish only and now comes with rack mounts.



I suddenly fancy a fat bike – Salsa Beargrease

The Beargrease is the new “racing” fatbike. At a very svelte 28lbs or so, this is one  (if not the lightest) light fatbike (in fact only 2 pounds more than my titanium carver rohloff beastie ….. Salsa Based this model off of their successful Mukluk, they cut all of the fancy braze-ons to save weight, and added quite the impressive parts list to achieve such a light fatty. It screams out for a frame bag and a sleeping bag and a real adventure …. 


The Beargrease is our ultimate snow and soft conditions racing machine.  Designed as our lightest and fastest fatbike, it is ready for the races.

Featuring our ultralight Beargrease aluminum fork and traditional vertical dropouts, Beargrease takes a minimalist approach to keep bike weight down, and speed up, while still delivering the necessary floatation to keep you riding in the soft stuff.

Floatation, floatation, floatation…a fatbike is nothing without floatation. Wide rims, and wide tires run at proper pressure for the conditions, make the difference between riding and pushing.

Effective frame geometry is equally important. Beargrease is stable and rides comfortably at slow speed, allowing riders to avoid dabbing in tough conditions. If conditions do force you to put a foot down, excellent standover clearance helps you stop and restart on narrow slow laden trails.

Beargrease features an anodized aluminum frame and fork. Anodizing doesn’t just look nice; It’s also lighter than a painted finish and much more scratch resistant and durable. The aluminum frame is lightweight and extremely corrosion resistant. Melting snow and adventures beneath the high tide line won’t cause the frameset to rust.

Whether it is a 40-mile weekend race, or the 1000-mile Iditarod Invitational in Alaska, Beargrease won’t hold you back.

Beargrease. Leave a fresh track.
