Surly Bikes is a designer and importer of bicycles, frames, parts, and accessories based in Bloomington, Minnesota, established circa 1998. Surly is owned by and shares facilities with Quality Bicycle Products (QBP).[1]

The company is well known in bicycle messenger and single-speed culture[who?] and helped establish the Single Speed World Championship (SSWC). Surly specializes in steel bicycle frames. Frames are made in Taiwan from 4130 chromoly steel.[2]

Distinctive components made by Surly include the Dingle cog, cranksets with separately detachable spiders, reversible chain tensioner, and the "Large Marge" an unusually wide bicycle rim. Surly also sells lifestyle items such as wool jerseys and flasks bearing the Surly logo.[citation needed]

Frame Models[edit]

In 2005, Surly began selling the Pugsley, the first mass-produced mountain bike with extremely large volume tires, up to 4 inches wide, for deep snow and sand riding.[3] The front and rear wheels share a common hub size and can be interchanged, allowing for redundancy and additional gearing combinations. Noted bicycle technical authority Sheldon Brown said, "Pugsley is, in its way, as revolutionary as the original mountain bikes were in the early 1980s."[4] Bicycling Magazine wrote, "It's not ideal for everyday use, but it can handle a wide variety of demands and conditions well."[5]

Components[edit]

  • Dingle cog: A two-speed track cog for fixed gear bicycles. It was released in early 2007. It is a multi-speed fixed-gear cog that is compatible with standard track hubs and lockrings. Three gear combinations are available, 17t and 19t, 17t and 20t, as well as 17t and 21t. When used with two appropriately sized chainrings, the rear axle's position in the dropouts can remain almost the same and still allow a relatively large difference in gear ratio between the two combinations. Bicycle Fixation's Harold Ikerd wrote, "The ability to change gear ratios while on the trail, road, or lost is heavenly!"[7]
