SRAM Force D1 DUB Wide Crankset

The SRAM Force D1 DUB Wide crankset is a 12-speed road double with 43/30-tooth chainrings, designed for bikes with drop handlebars and a 2x rear derailleur. The spacing between the chainrings is wider, making room for wider tyres: the manufacturer specifies up to 700x45C or 27,5x2,1 inches, but only with the 43/30 chainring. X-Range technology provides a wider gear range and smoother progression.

A Force wide front derailleur is required. The DUB accepts both road-width and MTB bottom brackets. The version offered has a 177.5 mm crank arm, a 47.5 mm chainline and a 94 mm chainring diameter: check these measurements against your frame before purchasing.

Founded in Chicago in 1987 by Stan Day and a group of cycling enthusiasts, SRAM is still based in the US city today. It makes drivetrains and brakes for road, gravel and mountain bikes. Its story began with a single product: Grip Shift, the shifter that lets riders change gear by twisting the grip.
