- The carbon crank arms are completely hollow with all unnecessary material being removed from the centre core - no internal aluminum spine

- 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
