I've purchased some shorter cranks for my SRAM Force AXS eTap bike, and I'm trying to decide between learning and swapping them myself vs. bringing it into a LBS.
Pros of doing it myself:
- learn for the future
- save money on LBS costs (plus I'd have to pay for a cab there/back)
- My bike is very expensive and I'd hate to break something/have something go wrong on a ride
- Would need to buy a larger torque wrench (not a huge con given I'll have one for the future)
- Minor, but I'm slightly worried my small torque wrench isn't very accurate, I left it at 6nm for a month or so instead of the lowest setting
As far as I can see the process would be:
- Loosen 2mm preload adjuster and unscrew
- Take off crankset with 8mm hex
- Take cranks off spider by undoing the 8 T20 bolts
- Swap and replace bolts at 4NM (greased?)
- Grease spindle and splines
- Install and tighten again with 8mm hex at 54NM
- Tap crank side with mallet and retighten preload adjuster, make sure no play Would be great to get some opinions on how easy of a job this is for a bit of a noob. What to look out for/what parts will be hard/whether I've missed anything.
Thanks in advance!
These are the sources I've used to get the above info:
