Wash my bike properly? At the moment it's caked in mud. But the chain is clean. I'm going out for a night ride in an hour and no doubt more will be added. Do I carefully jet wash the bike on the way home. Or let the mud dry and bar it off and lube the chain.
Basically, if the transmission is clean and any fork/dropper seals and stanchions are clean, then the rest is superficial.
It is nice to set off on a ride with a nice shiny frame, but realistically that will be gone twenty metres into the first off road stretch.
I wipe down the forks after every ride. Only recon golds but most expensive fork I've had so don't want them knackered. The transmission is a mix of altus and acera which unwanted to replace eventually.
To an extent it depends where you ride and where you keep your bike.
My bikes live indoors, and most of the places I ride have either sandstone or gritstone and a lot of mud. I tend to let the bike dry for a few hours or overnight and then brush most of it off with an old dustpan brush, then give it a quick sponge down with warm water and car shampoo and quick hose off before running the chain through a chainscrubber with soapy water and using a wahing up brush pushed into the cassette and jockeys while cranking back on the freewheel.
If I'm riding a lot that week this tends to slip heavily to a once a week treatment. The actual wash takes me less time than a mug of tea to go cold outside so it's not excessive. I find that if I try to hose it down while the mud is still heavily clagged on and wet it takes much longer and much more water in addition to probably being far worse for bearings, seals etc.
I don't feel this is excessively OCD, but I have a riding buddy that can count the number of times his bike gets cleaned. His bike doesn't catch fire and he doesn't die although his drivetrain may not last as long...
