Maintenance is key to many, may hobbies. Cars require regular service. Airplanes ditto. Computers are a nearly constant maintenance nightmare. Bicycles, to many, are devoid of this requirement, and thus the horribly damaged frames I’ve ended up.
There are only a couple rules here, it’s simple, people.
1. If it moves, grease it. Seriously now. Brake studs? Grease em’. Threads on anything? Sure, grease away. If it’s not the rims, the tires, or grips, put grease on it. It won’t hurt, and it most certainly will help. The bike frame I’ve ended up with may be ruined because of a failure to grease bottom bracket threads, and the previous seatpost-bound frame was almost certainly a product of no-grease seatpost installation.
2. If it breaks, replace it. That brake caliper you’re leaving dangling in the wind isn’t helping anyone. Cables are cheap and it would cost almost nothing to fix. The rear rim is wobbly? A quick true-up might cost twenty bucks, but it’s not gonna be the end of the world.
3. THERE ARE ONLY TWO RULES.
Seriously? Is that hard? I mean, damn. The sheer number of bikes I see around that are just destroyed by usage is disgusting. Now I have to make the hard choice of trying to figure out if I can get the little sliver of BB out of this frame without buggering the threads, buggering the threads and replacing it with one of the thread-free cone types, or finding YET ANOTHER FRAME for this cheap bike project. Next time you take the old bike out, oil something that squeaks, and hopefully when you sell it, there won’t be someone out there cursing the day you were born.
