The NGeco MTB e*thirteen Single power meter (boost) is compatible with all e*thirteen XCX-, TRS- and LG1-cranksets. A chainline adapater is included into this powermeter set. The chainline of the powermeter including the adapter is boost (52mm). Without the adapter the powermeter can also be used for the super boost or AI-chainline (55mm). The powermeter replaces the direct mount chainring, therefore a new chainring with BCD 104mm is needed.
