NGeco MTB SRAM single power meter (standard)
The NGeco MTB SRAM single power meter spider (standard) is the power meter for all mountainbikers who already use a direct mount SRAM single crank set or a modular SRAM crank set with a Q-factor of 168mm (these cranks use 3 bolts to tighten the spider). This powermeter also works with Truvativ cranksets. Please note, that the powermeter replaces the direct mount chainring. You will need a new SRAM compatible chainring with BCD 104.
The NGeco MTB SRAM single power meter (standard) spider is for the standard chainline.
