Unique crank arm / chain ring setup.  Appears the two crank rings and ring guard are one unit, while the arms are seperate and fit together.  The Adamas front crank set comes in several different versions including a single and double set up, several different gearing sets.  There is also the AXII version which does not have the ring guard.
