Better make sure you buy a chain that comes with a quick link.
I like KMX.

Today's most unsatisfactory and wholly rubbish bicycle maintenance

I have a bike that mostly lives on the turbo trainer. Something has felt wrong with the pedals for the past week or two. While it felt odd, when I was riding it I couldn't feel any play in the bottom bracket. I decided the cleats might be worn.
On Saturday, for the first time, I got off the bike before I rocked the cranks back and forth and found a lot of play. Like a lot lot.
Ho hum. Wrestled the bike off the turbo and put it on the stand.
Removed the cranks. Removed the bottom bracket. I had to stand on the spanner to get it to come loose. Replaced bottom bracket with one from my parts drawer. It was a no-name brand ('Prowheel') in a Shimano box, but seemed to be used (and I hadn't written a note on to say why).
I put the new bottom bracket in and replaced the cranks. When I loaded the bearing it either had too much play or it was binding. Clearly, the bottom bracket that I had carefully put back in a Shimano box was also defective.
Removed the cranks. Removed the bottom bracket (didn't have to stand on the spanner this time). Replaced bottom bracket with one from my parts drawer. It was an Ultegra one, but I'd written on the box 'LHS Bearing U/S??'. I seemed to recall that actually when I'd written that in 2022 I thought the bearing was broken after I'd taken it out of my audax bike, but then realised that the weird intermittent ticking noise that started on the Glen Ogle bike path was actually due to a broken mudguard.
I put the new bottom bracket in and replaced the cranks. When I loaded the bearing it seemed OK, which was lucky, as I did have another (brand new) bottom bracket in my spares box, but might have had a sense of humour failure at that point.
Moral of the story. If you are going to retain previously-used parts 'just in case' then take care to label them properly so that, three years later, you know if they actually work or not...

That BB from the parts drawer would have made a great PY Xmas gift.

-1 cursed bottom bracket
My parts box could definitely use a few Scrolls of Enchantment...

On that note can I interest anyone in a Bontrager crankset? Could not possibly comment on the invidious effect it has on the driveside bearings to the point I have returned to square taper
(-2 cursed crankset... to go with the bottom bracket)

Due a miscalculation of scale not seen since the Vl'hurgs, I've just spent the evening fitting a 9 speed chain on a 10 speed cassette/mech and wondering why I can't get it to run smoothly.
