When I oil my bike chain, I oil the inside and the outside like so:
1. Oil here ▼ ___________________ / \ | 2. And oil here ▼ | \___________________/
Cycle on 1/4 of the length of chain, and repeat 3 times, so that the top and bottom all the way around has had it applied.
Is this overkill? Do I need to oil both sides of the chain?
