NG MTB Rotor REX3 double -Set
The NG MTB Rotor REX3 double-Set consists of our NG powermeter, the Rotor REX3 crankset and the adapter for 2x drivetrains. The use of the adapter makes the crankset extremly flexible. Without the adapter the powermeter set can be used for the Boost chainline.
The REX3 Standard-Set is the ideal solution for all MTBs with older Shimano cranksets. It's 24mm spindle fits perfectly into the Shimano bottom bracket and the cranksets can be changed easily.
