RockShox Fat Bike Fork: Bluto RL – Official Update Added

The Fat Cat's Out of the Bag

RockShox is officially making a fatbike fork, and unfortunately it’s not called the Fat Pike. Rocky Mountain launched the Blizzard today and with that release came the conspicuous first photos and a few hints at spec.

The fork will be called the Bluto, with 100mm of travel, a tapered steerer, and a 150×15 axle. This particular model has a Motion Control DNA damper, which indicates a 32mm stanchion.

UPDATE: SRAM’s official release came through this morning. New photos and details below.

SRAM’s Official Release:

You’ve probably observed more and more riders are on bikes that look “different” on your trails. Bikes that have wheels and tires of gigantic proportion – and we’re not talking about 29ers here. The thing is, even though fat bikes were first created to float on top of snow and sand, they’re just too damn fun not to ride on dirt. So how do you amplify your fat bike adventures even further?

With a supercharged, ultra efficient, first of its kind fat suspension fork called BLUTO. We started with the features you’ve come to love from RockShox: Rapid Recovery rebound, Fast Black aluminum upper tubes, the infinitely tunable Solo Air spring, stout 15mm Maxle Lite, remote or crown adjustable damper, and tapered steerer tube.

Then, the chassis got the fat treatment by reengineering it to meet the unique needs of fat tires and wheels. Everything from crown, to arch, to axle has been optimized to tackle the increased torsional loads of its wide stance. With more traction and control than ever before, you’ll never be happier you went fat.

Well there you have it. What do you think?

  • Dave

    29+ compatible?

    • Maxime Blahr St-denis

      why would you want to set-up that fork on a 29er, i mean, it’s made extra wide and extra burly, wich means probably alot heavier than it’s 29er version. Not complaining just wondering why you’d wanna go with that more than a regular 29er fork

      • boomforeal

        29+ means 3″ wide tires, which many regular 29er forks can’t accommodate (though some can)

    • Vik Approved

      There are quite a few “normal” 29er forks that can fit a Knard on a Rabbit hole with a bit of modification with a dremel. A number have been done and I have not heard of any failures or issues from modding them.

      If you aren’t going to run fatbike rubber in them I’d stick to a standard fork and a standard hub instead of going to a 150mm wide hub and speciality fork.
