It took me decades to find out that working on bikes can be as enjoyable as turning pedals - even as a hopeless amateur at both.
With good music, no time pressure and a coffee, I reckoned it would be time to replace the 8-speed chain & cassette today, as 2 years had passed since the last KMC X8 & Microshift (12- 32). Surprised to find the chain is still within 0.5 -0.75 mm on the Pedros checker.
Next, the bike & drivechain were thoroughly cleaned, polished & waxed.
A lowly Shimano dynamo hub* had the cup/ cone bearings regreased & adjusted. It's a bit delicate on the drive side - there's a risk of breaking the copper wire. Also, the magnet/ cogging effect affects how you judge the bearing preload setting.
Finally, M+ tyres were picked clear from all debris/ glass shards, etc, reseated & set back to 3 bar.
A good day.
*Have to praise this DH-3N20: 14 years done, still on original cones & working flawlessly. Kudos to SJSC for carrying spare cones at a very reasonable £3.99:
