The SRAM MTB power meter spider is the power meter for all mountain bikers 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.
There are two options available to choose from, either the power2max NG unit, or the power2max NGeco unit (see specifications below for differences between the two models).
power2max NG specifications:
- +/-1 % data accuracy
- advanced power meter metrics
- a rechargeable battery
- data transmission via ANT+ and Bluetooth
power2max NGeco specifications:
- +/-2 % data accuracy
- standard power meter metrics that can be upgraded
