Surly Bikes is a bicycle company based in Bloomington, Minnesota founded in 1998. They design bicycles, components, and, most notably, steel frames which are manufactured in Taiwan using 4130 chromoly steel.[1] Surly is owned by and shares facilities with Quality Bicycle Products (QBP).[2]

Components made by Surly include the dingle cog, cranksets with separately detachable spiders, a reversible chain tensioner, and fatbike rims. Surly also markets branded lifetstyle products.[citation needed]

Frame models[edit]

In 2005, Surly began selling the Pugsley, a mountain bike with large volume tires — up to 5 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]

A Big Dummy with handlebars and foot rests for a second rider

In 2006 Surly introduced the Big Dummy, a longtail bike frame designed for the Xtracycle Free Radical extension that can carry 200 lbs of gear in addition to a 200 lb rider.[citation needed] In 2016, Surly announced an updated version of this cargo bike, which they called "The Big Fat Dummy." This model is similar to the original Big Dummy, but with fat tires, a longer top tube and a slacker head tube.[6]

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!"[8]
  • Singleator : A simple, effective and inexpensive way to convert bike to a singlespeed. It will adjust chainline and spring tension.
  • Cranks : MR.WHIRLY It is an incredibly versatile crank. The modular design allows to replace bits of parts, instead of replacing the whole crankset. It swaps spindles to use it with 68,73, and 100 mm bottom brackets. Armsets of various sizes are available in 165,170,175, 180 and 185 mm lengths. Spiders come in 3 BCD's; 94, 104 and 110. There are also complete options in singlespeed and triplespeed.
