Hi,
Looking for some help with compatibility when looking at crank-based power meters.
I have a TT bike with the SRAM Rival AXS DUB 48/35 2x. (https://www.sigmasports.com/item/SRAM/Rival-AXS-DUB-Chainset/TOCT?jml_model=recently-viewed-items-local-storage&id=1384597)
I was looking at upgrading to a left sided crank based power meter but my searches are bringing 2 different-looking cranks at different prices:
- https://www.tredz.co.uk/.SRAM-Rival-DUB-Power-Meter-Spindle-Left-Crankarm_238592.htm?variations=colour:Black,option:165mm&sku=796196 at £199
- https://www.tredz.co.uk/.SRAM-Rival-E1-DUB-Left-Arm-and-Power-Meter-Spindle-Right-Arm-BB-Spider-Chainrings-not-included-_275264.htm?variations=colour:Left%2520Arm%2520and%2520Power%2520Meter%2520Spindle,option:165mm&sku=1024611 at £146, but this is a different-looking crank and I can't find any info on inter-compatibility.
They are both SRAM Rival, both for 2x setups, both aluminium. It looks like the E1 range is the higher end crankset but the power meter crank is cheaper. I don't want to upgrade the full chainset as it's unnecessary and more expensive.
Can I buy either? Or should I just get the first one which is definitely an identical crank to what I already have?
Thanks.
