Pure: Frame not realeased. Control: Description - The long-serving Control frame, still favoured by many due to its relatively low BB rise. - Full U6 alloy construction. - Top and down tube gussets at the head tube to make sure the frame lasts excellently. - Built in one piece CNC brake booster to give precision and powerful braking. Also provides stronger seat stays and more rigid rear end. - One piece CNC BB shell and chainstay yoke allows for 375mm chainstay length, as well as excellent tire clearance. - Notorious U6 tubing as last year, still with none of the Pure or Control frames cracked from 2003 til present day! Geometry Wheelbase: Short 1065mm, Long 1085mm Chainstay Length: 375mm BB Rise: 10mm Head Angle: 72 degrees Centre of BB shell to top centre of head tube: Short 665mm (26.25"), Long 685mm (27") Go for the Pure, there cheaper and nobody has one Hope i helped mate.
