These cutting edge tensioners are CNC’d from 6061 T6 aluminum & feature a revolutionary single screw adjustment system. Unlike some chain tensioners, the Solo’s use a proprietary 2.5mm single adjusting screw that operates independent of a “C” ring or Clip device, allowing for smooth & reliable adjustment of your drive train - every time. With only two moving parts, these are one of the most reliable & convenient chain tensioners on the market. In addition, our new tensioners come equipped w/ axle shims to accommodate M6 Allen bolts commonly found on mini & expert size wheel sets, eliminating any space between the axle & tensioner to ensure consistent & accurate adjustment. The ultimate marriage of form & function; everything you have come to expect from Crupi.
