What power meter will work with my super boost MTB crankset?

The majority of modern mountain bikes use boost spacing. Bikes with boost spacing use 148 mm rear hubs and have 52 mm chainlines. Recently, some manufacturers have moved to what’s called super boost. On a super boost frame, you have wider 157 mm rear hubs and 56 mm chain lines. These bikes require wider cranks as well.

Since super boost is still a relatively new standard, there aren’t a lot of options for it at the moment. It’s also to be determined how many manufacturers are going to embrace this new standard. Currently, there are two power meter options for super boost frames.

 

Spider Power Meters

power2max NGeco e*thirteen MTB Power Meter

power2max makes the NGeco e*thirteen MTB Power Meter. This is a spider-based power meter that measures power from both legs. power2max makes great units – affordable, accurate and very reliable. However, as the name implies, this power meter spider is made specifically for e*thirteen cranksets including the XCX, TRS and LG1. If you currently have one of these cranksets, you can bolt this power meter spider directly on, otherwise, you will need to buy the e*thirteen crankset in addition to the power meter.

 

ROTOR INspider KAPIC MTB Power Meter Crankset

ROTOR also makes a spider-based power meter, the INspider. When paired with a ROTOR MTB crankset and super boost spindle, the INspider MTB crankset will fit nicely on super boost frames. Like the power2max above, the ROTOR INspider measures left and right leg power and if you opt for the KAPIC Carbon crank arms, it’s a very high-end, full carbon crankset. It’s not cheap, but you get what you pay for! Note that you can also opt for non-carbon KAPIC, Hawk or Raptor cranks which are more affordable.
