A hose down after a very muddy ride is one thing, but regularly washing (after each ride) to keep it in showroom condition seems somewhat pointless to me. I am not saying that a clean bike doesn’t look good, but the amount of time and effort required for me to wash my bike, only for it to be all muddy again after one ride doesn’t make sense.
True, but I tend to find enough stuff going wrong when I wash it that would ruin or at least interupt a ride to make it worthwhile, stuff like brake pads worn, or broken parts, or loose bolts, or fixing that slow puncture. Once the bikes in the workstand it only takes 10 minutes with a bucket, brush, sponge, chain cleaner, cassette cleaning brush doodahh and a bottle of degreaser to get it showroom clean and it’s far easier checking/fixing stuff when it’s clean. So all the monthly jobs like indexing gears and lubeing cables can all be done at once too.
My winter bike has no gears, a CK BB and hope brakes though, so gets a sum total of no maintance as appart from splittig the rear hub completely in 2 nothign has ever gone wrong!
