• Industry standard 30mm spindle with Cinch spline interface. The spindle is CNC machined from a newly commercialized aluminum 'super alloy' that is 20% stronger than 7050 alloy (the alloy commonly used in this application)
• Removable spider offers the ability to convert between existing chainring standards while remaining flexible to future developments.
• The interchangeable spindle option of the Cinch system allows you to use the same crankset with 68/73mm and 83mm frames
