I'm getting some creaking in my crank/bottom bracket and a good first step towards fixing this is to remove and clean the cranks and chainrings. If I still have the creaking, the BB is almost certainly the problem. However, I've hit a roadblock; I've got the big and middle rings off, but I can't remove the crank arms to get the small ring off the bike.
Looking up Shimano Hollowtech cranks isn't giving me any help, I don't have the Hollowtech II crank and all those direct me to loosen bolts that aren't on my crank arms. Can anyone identify exactly what crankset I have? How can I safely remove and clean all this?
- Novara Randonee touring bike, circa 2008
- Bottom bracket: Shimano Octalink (as per this, so maybe?)
