Had my service done at a dealer for a change, and on the way out the guy at the desk says that they adjusted my chain as it was too slack. Odd, I thought, I checked it recently and it seemed to be in the middle of the range.
Didn't think much of it at the time. Then I started noticing an odd noise from the bike, sounded like the chain. So I had a look at it. It had ZERO slack!
I could barely move the thing.
Whoever "adjusted" my chain clearly had no clue about what they were doing. Obviously couldn't be bothered looking up the specs either. I think I'm going back to doing stuff myself, thank you very much.
