## Description

Designed to perform on the streets, the velodrome, and everywhere in between, the affordable Pure Fix Keirin double-butted 6061 aluminum frameset is ready to take you to the next level of riding. Pure Cycles offers two options -- the Keirin and Keirin Pro -- that are ideal for riders who got hooked on fixed bicycling with their first Pure Fix Fixie. The Keirin frameset with double-butted 6061 aluminum tubing is designed to give you the edge on the track and the streets. Featuring an integrated headset and smooth welds, it’s light, stiff, responsive, and ready for anything from a criterium to a commute. This frame also has an aerodynamically improved fork, hydroformed top tube and seat tube, 31.8mm seatpost clamp, and 68mm English threaded bottom bracket. Both the Keirin and Keirin Pro are available in five sizes with a weight range of 4 pounds, 8 ounces to 5 pounds 4 ounces:49cm: Fits riders 4 feet, 11 inches to 5 feet, 2 inches52cm: Fits riders 5 feet, 2 inches to 5 feet, 7 inches55cm: Fits riders 5 feet, 7 inches to 5 feet, 11 inches58cm: Fits riders 5 feet, 10 inches to 6 feet, 1 inch61cm: Fits riders 6 feet to 6 feet, 4 inches  Aluminum bike frames can have double-butted and triple-butted tubes that have different thicknesses, allowing the frame to handle high-stress points at the end of the tubes without having additional weight through the middle. Double-butted frames add extra material at each end of the tube where additional strength is required. Triple-butted frames use the same process, but reduces weight in the center even more.Celebrating bicycling for all that it offers, Pure Cycles offers a variety of frame, geometry, and gearing options as well as a cornucopia of compatible accessories, including different styles of handlebars, saddles, water bottle cages, foot straps, and more.

The headtube was dented around the top headset bearing seat, preventing installation of the headset, and making the frame useless.Close inspection reveals it probably came from the factory this way and somehow got through quality control. It appears to not be shipping damage, because the metal is rough under the paint, meaning it was probably dropped before it was even painted.
