Surly Pugsley Frame, Blue
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 comes with an internal ED coating, which is a process that coats the frame inside and out with a protective layer that provides a foundation for the finish and gives 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.
