AT

Brand: Sugino

The Sugino AT was a 1980s forged aluminium-alloy triple crankset designed for touring and mountain bikes. It was the first crankset built to the 110/74mm BCD pattern (110mm for the outer and middle chainrings, 74mm for the granny ring), which went on to become the standard triple road/MTB bolt pattern. Available in 165, 170, 175 and 180mm arm lengths on a JIS square-taper spindle with English pedal threads.
