Many moons ago we began producing the Pugsley because we wanted to ride a bike that could be ridden where other bikes simply faltered. In order to do that, we figured this bicycle needed to have floatation and traction the likes of which have never before been seen. Pugsley is our brilliant solution to this – and it seems to work. This bike rolls through all the sloppiest slop around.
The Pugsley frame is equipped with 135mm spaced horizontal rear-loading dropouts with a derailleur hanger. The rear end of the frame is offset 17.5mm so any type of drivetrain setup can be used without having to worry about chain-on-tire rub. Pugsley frames also come with an internal ED coating. This is a process that coats the frame inside and out with a protective layer to provide a foundation for the finish and give an added level of protection from corrosion on the inside of the frame. We still recommend treating your frame with a protectant such as Framesaver or Boeshield.
Pugsley is available as a frameset only. The frame will accept tires up to 3.8”wide on 84mm rims. The fork is a 135mm spaced symmetric version with extra water bottle cage brazeons on each leg and can handle a 4.8” tire if you want to run the big meats up front. Being the supremely versatile machine it is, the addition of an offset fork gives the rider the ability to swap front and rear wheels. This can be especially handy if you were to find yourself with a blown freehub or completely annihilated rear derailleur in frigid temps or stranded deep in the indifferent forest.
