After Mrs GB and i had a little, err, disagreement this morning i’ve finally fixed up her Bobbin. That horrible pile of crap that takes up loads of room in the shed and weighs about 63 tonnes!
I learned how to adjust a Sturmey Archer gear hub thing and patched the puncture up (didn’t have any tools to get the wheel off the last time i tried as the gearing mech thing had all jammed up tight). Even though i’m still annoyed with her method, it was clearly successful as i’ve done it now and i’ll have a few reluctant brownie points! 
A friend is reporting that his shifting down the cassette isn’t working properly, but going up the gears is fine.
My assumption (without seeing it) is the indexing is OK and that the gear cable isn’t moving freely when it is slackened, so the fix is likely to be new cables.
Is it likely to be anything else?
Could be the RD pivot is stiff and needs oil, the grub screws holding the gear hanger on or chain wear. All do weird stuff to indexing

OK, so a few things to check. Gives me a chance to use my chain checker and derailleur alignment hanger tools!
I fond out Saturday that a guy I regularly ride with doesn’t know how to fix a puncture/swap a tyre and or tube out 
Came across this today. Looks like it would be pretty good for bike maintenance idiots like me. Saves hunting on YouTube for stuff and had an "offline’ section for. roadside repairs.
No affiliation or anything, just tempted to give it a crack for the sake of 4 quid.
Long story about the most pathetic puncture repair ever:
Me and 2 guys from the Tri club decided to have a bit of a change so took the MTBs out on Sunday for a loop of the canals around Worcester. We would all consider ourselves pretty decent in the spanner wielding stakes which makes our pathetic failure even more embarrassing.
We get to the furthest point from home and James gets front wheel puncture so we stop to fix it. He says he’s a bit concerned as it was flat yesterday and he put a new tube in so maybe there’s still something stuck in the tyre. He gets the tyre off and I start checking it and find a tiny thorn that only appears when you flex the tyre. He’s got a spare tube so all is good and we carry on.
A mile down the road front tyre is flat again so he says there must still be something in there, he doesn’t have another tube but has brought a repair kit as back up. I’ve got a tube in my pack but it’s Presta and his are Schrader. We check the tyre again and can’t find anything, he dunks the tube in the canal and the puncture is directly opposite the valve, just like the first one, but the chances of putting the tyre back in exactly the same place are miniscule, at which point he realises he must have had the same puncture in the past and forgot to replace the tube so has been carrying a punctured tube around.
So he resorts to the puncture repair kit but when he gets it out, the glue and patches are so old they’ve all dried up and won’t stick, he’s out got nothing else left.
Both me and the other guy have Presta valves but they can be used at push so we turn to our packs, other guy then realises his isn’t attached to bike, must have left it at home, he’s out.
Go to my pack, get tube out and miracle of miracles it’s a Schrader valve, we can’t believe out luck, must have been in there a few years since a family holiday when we had both sorts of valves and I’ve been carrying the wrong sort every since. Result.
Start fitting it to wheel and ooops, it’s a mile too short, must have been from family holiday but for my son’s BMX which we don’t even own anymore. I’ve been carrying it around for years just assuming it was an MTB one. Doh!!!
We’re completely out now and have nothing left so the 2 of us with functioning bikes ride to the nearest town where there’s a Wilko, buy a tube and a repair kit then back to the stranded guy. I didn’t have a face mask as hadn’t planned on stopping so had to walk round like Quasi Modo with my jersey zipped up over my face.
We got what we needed and completed the ride, it was a nice day and we all had a laugh about it but there is a lesson there about checking what’s in your pack, especially if you change between bikes etc.
In the end I think it was about an hour to deal with a single front wheel puncture!

I have been quite lucky with punctures, to the extent that when I was finally struck down during lockdown last year, I discovered both the spare tubes in my pack were perished. Luckily take-away service had just been allowed to open so I could sit outside in the sunshine with a coffee while I waited for rescue.

A friend decided the best way to fix a puncture during an IM was to replace the punctured tube with the punctured tube, oops!

There is nothing more tragic than my now 40 year old group of mates calling each other other ‘bro’ and shouting ‘send it’ down a modest trail at the Forest of Dean.
Still doing it though, but I don’t allow my MTB shorts to extend below the knee.

I know there’s no chain, but do you think I need to clean this before I ride it again, or will it just clean off in the ride?

TOO MANY WATTS

I like to think that’s what bent two of mine (cheap ones). Was probably too many pies though.
