Yesterday was a very good day.
Finished my early shift and gave Mike (the retired gentleman who works on bikes) a ring. After a little chat he told me to bring it down.
Once up on his stand, he made a couple of adjustments to the H screw on the RD, and voila! No more chain skipping on the 12T!
It was a little puzzling as I'd made similar adjustments with absolutely zero change, so had reset the H and L screws to their previous position.
Anyway we found the chain was still not quite shifting right, and no matter what barrel adjustment Mike made couldn't get it working perfect both ways - it either skipped gaining up the cassette or coming down.
So Mike contacted a LBS round the corner as he knew the mechanic and the guy told me to bring it round.
So after popping £5 into Mikes charity box (as he didn't want any payment for his help) I whizzed round to the LBS where the bike was inspected. Found the RD was slightly bent, which I reckon was from my fall on the tramlines late last year, so dismantled that, got it back into perfect shape, greased the cable near the RD and made a couple of other adjustments and voila! A perfect shifting drivetrain.
The mechanic didn't even want any payment so I plan to use them for the full service I will do in a few months time.
On top of that, I got an email from the German website I used to buy the expensive LS950 front light 2 years ago (which went wonky on my last ride) to say they have repaired it and are returning it to me. Quite surprised as it's been a good 2 years since I purchased it.
Felt like putting some cash down on the lottery after all that.
Yay!
