Replacing cranks on SRAM Force AXS
Looks like you have done the research and You have a good idea of what you want to do and how you are going to execute it. You have a torque wrench and know what the torque specs are.
The only thing I have found difficult about crank replacement is the axle can be tight in the bearing inner races and requires some force to get it through.
If you want to learn go for it. If things go wrong you can always go to your LBS.
