Sram:
Power every ride. We've taken the reliability, elegance and features of Quarq’s legendary crank-based power meter and dropped the barrier to entry once again. This new power meter platform is entirely contained within the dub spindle for clean integration that fits more bikes than ever.
The SRAM Rival AXS Power Meter Crank Arm comes in two versions: Regular and Wide. The regular version fits most road bikes, whereas the wide version uses a longer spindle and is meant for bikes with larger tyres such as cyclocross or gravel bikes. If you have a Rival DUB Regular crankset on your bike, you need to order the Regular power meter option and if your Rival DUB crankset is Wide, then you need to select the Wide power metre option.
In most cases you can determine which version you have on your bike by your chainrings:
- SRAM Rival DUB 1X - Wide
- SRAM Rival DUB 2X 43/30 - Wide
- SRAM Rival DUB 2X 46/33 - Regular
- SRAM Rival DUB 2X 48/35 - Regular
If you want to be 100% sure which version you have and leave nothing to chance, you will need to pull the cranks off your bike and view the writing on the spindle. If you have the Regular version, you will see the words 'DUB' printed on the spindle. If you have the Wide version, you will see the words 'WIDE' printed on the spindle.
