Ritchey Commando Fat Bike Frameset - 2017

The original Ritchey Commando was designed to be a mountain bike with no limits, a machine to conquer cow trails and dry river beds in the days before mountain bike trails. Now that adventurous spirit lives on in the 2015 Commando, with Ritchey's four decades of framebuilding mastering bringing the light and nimble feel of a Ritchey to the world of Fat Bikes.

Geometry Information

Great frame, great price. Exactly what I needed as a Fat bike upgrade. Will take bigger than 26x4 tyres, with a 1x10 chain set I've built mine up with 4.6" tyres with no issues.
Ritchey Commando frame is extremely good frame. I built it with 29+ wheels and it takes easily 3" tires. Stiffness and smoothness are in perfect balance. Steering is neutral, quick and playful but also steady and calm. No problems in difficult rocky terrain and rolls over anything nicely. The best do it all bike ever. For the price I feel like I won lottery.
Great frame for a fantastic price. I am yet to build it up but the build quality is top notch. It has been a bit of a hassle chasing down the right headset for this frame as one was not included.
shockingly light! arrived in the USA perfectly intact. Gorgeous, graceful lines-I NEVER expected to describe a fat bike frame to be graceful and elegant but this certainly is just amazingly so. SAFE, last a lifetime, quality triple butted steel. Just be aware of the following: *Only has one boss on each fork leg located mid front fork for a front rack (not two for a WB/cargo cage). (has bosses by fork and rear dropouts for racks; and bosses rear upper by seat for rear rack-fork is drilled in center "crown" area for upper front rack) *No third WB/fuel bottle bosses under downtube. *Will not accept Rock Shox Bluto fork *It accepts 135F 170Rhubs, which will become less common(150/15/190/12 likely new "standard"). I got the SUPERB (but heavy rear) Fatback hubs/QRs for a mere $120 USSD!!! so I am well set. *It is officially rated for "only" 4" tires, but I have seen Inet pics of people using 1x front chainrings using 5" tires If it had two WB bosses on fork legs, fuel bottle/3rd WB bosses under downtube; and Breakaway design, it would be THE IDEAL adventure bike! As is, it is still a FABULOUS bike at an insane deal.
So far, this looks like a fantastic deal. I have a Surly Pugsley and this frame is noticeably lighter. Standover is more generous than the Pugsley as well. I like the drab green finish, the integrated headset, and not having to deal with offset wheels and rearward opening dropouts (technically rear fork ends, as the wheel is unable to "drop out". Most of the parts will change right over from my Pugsley, except for the wheels which require new hubs front and rear. I look forward to getting this bike assembled, sorted and ridden
