Product Description

We won’t beat you over the head re-explaining the idea of the Pugsley or fat bike theory. If you’re looking at this bike there’s a good chance you already know what you’re looking at, and if you don’t then check out the Pugsley and Moonlander pages. There’s plenty of info there to get you up to speed. Pug Ops shares the same frame as the standard Pugsley, and it has the same non-offset fork. The fork has clearance for 4.8˝ tires on 100mm rims, it’s spaced for 135mm hubs and has cage-mounting bosses on each leg for running either standard bottle cages in a high or low position or a larger gear cage. It isn’t just the wider rims that set it apart though. Where the standard Pugsley sports 3.8” tires on 65mm rims and the Moonlander runs 4.8” tires on 100mm rims, Pug Ops has 3.8˝ Nate tires on 82mm Rolling Darryl rims, increasing the footprint of the 3.8” tire, and thereby its float and traction, while keeping the wheel weight lower than Moonlander. Many of Pug Ops’ parts are nicer. It gets our O.D. crank with 36/22 rings, 60tpi Nate 3.8˝ tires, a mix of SRAM X7 and X9 derailleurs, 180/160mm front/rear rotors with all black SRAM Guide RS hydraulic disc brakes.
