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 148 mm, and sometimes even wider 157 mm rear hubs and 55 mm – 56.5 mm chain lines. These super boost bikes require wider cranks to fit the wider chain lines.

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. However, there are a few power meters that fit super boost frames. As you review the options below, take note of what the resulting chainline is for each option. For example, some power meters give you a 55 mm chainline, whereas others might give you 56.5 mm. It’s important you go with a power meter that results in the correct chainline for your bike.

 

Super Boost Spider Power Meters

Quarq SRAM XX1 Eagle DUB Power Meter Crankset 

Quarq makes the XX1 Eagle DUB Power Meter. This is a spider-based power meter that measures power from both legs. When ordered with the Super Boost 55 MM chainline, it ships with the extra wide XX1 Eagle cranks and the resulting chainline is super boost 55 mm. Please note this crankset requires a SRAM DUB bottom bracket.

Please also note, if you already have the SRAM XX1 Eagle DUB 8-bolt 55 mm cranks on your bike, you can order just the power meter in the Boost 52 MM chainline (without new cranks) and bolt the power meter directly onto your existing 55 mm cranks and the resulting chainline will be 55 mm.

power2max NGeco SRAM MTB Power Meter + SRAM XX1 Eagle DUB SL Crankset

power2max makes the power2max NGeco SRAM MTB Power Meter – one of our most popular MTB power meters. This is also a spider-based power meter that measures power from both legs. power2max makes great units – affordable, accurate and very reliable. When paired with the SRAM XX1 Eagle DUB SL Crankset in the Super Boost 55 MM version, your resulting chainline will be super boost 55 mm.

Or, if you already have SRAM 3-bolt super boost cranks on your bike (XX1 Eagle DUB SL or GX Eagle DUB for example), you can order just the power meter in the 1X Boost 104 BCD chainline (without new cranks) and bolt the power meter directly onto your existing super boost cranks and will maintain your current super boost chainline.

power2max NGeco e*thirteen MTB Power Meter

power2max also makes the NGeco e*thirteen MTB Power Meter for super boost 55 mm chainlines. This is also a spider-based power meter that measures power from both legs. 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 KAPIC Carbon MTB crankset and super boost spindle, the INspider MTB crankset will fit nicely on super boost frames with chainlines between 55 mm – 56.5 mm. Like the power meters above, the ROTOR INspider measures left and right leg power and it comes with carbon KAPIC crank arms.
