It's a convention, and it would be pointless to have 2 competing standards when neither offers an overwhelming benefit. Right hand threads are easier for the right handed majority to tighten. By the same argument, left hand threads are easiest for the right handed majority to loosen. For comparison, in the world of motorbikes, the rear sprocket is not screwed on but is held on with several bolts so the handedness of a single central thread is not an issue. A motorbike drive chain is usually, but not always on the left. This is because most people usually mount from the left, so the kick stand is on the left to lean the bike that way. Therefore the chain is on the "downhill" side and more sheltered when the bike is parked in the rain. The explanation about mounting from the left due to the sword scabbard is interesting.

There are notable and rather common exceptions: the aircooled Harley Sportsters (they might usually have belts though, not an HD expert, but the same principle), Buells which used the Harley engine, the classic looking modern Triumphs (Bonneville, Speed Twin, Speedmaster, probably forgetting something) and the KTM LC-4 series (edit: and the small BMW GSes). At least. Don't know exactly why these makes have ended with the right hand drivetrain, especially the Triumph, I though it would be because of "British tradition" but quickly image-searching it seems that all the classic British bikes from 50s-70s had a left hand chain, including the original Bonnevilles.

Love the nerdy stuff, more please. Something I've always wondered, especially after a nasty crash on my mountain bike, is why the derailleur points down putting it closer to the ground and in range of rocks etc Surely the derailleur spring tension would be sufficient to stop the chain from sagging if it was redesigned to be flipped to point up. Or am I missing something totally obvious to why it's not possible?
@marlon6972
9 сағат бұрын
The RD is positioned downwards because it's the load-free part of the chain (only tensile forces come from the RD spring). Flipping the RD to the top would cause several problems, as all the loads would then travel through the RD, cage, spring, etc. You wouldn't even be able to use a spring, as any force would just deform the spring instead of driving the bike forward. Additionally, shifting would become much more difficult-you would always need to freewheel to shift, and any force on the pedals would make it impossible. You’d also need beefier RDs and cages to withstand the forces, and there would be efficiency losses due to deformation of these parts. While you could theoretically make the chain cross between the chainring and cassette to flip the RD, that would lead to even bigger issues

It's probably just historical convention, and the fact that most off the shelf gear (cassettes, derailleurs, cranks, chainrings) are designed to be on the right. Who in their right mind is going to design a bike that requires custom parts, without a very good reason? Probably nobody. Now, it's not that hard to make left handed screws, and in fact bikes do have some left handed hardware, but they're few and far between among the right handed drive trains. So yeah, probably just historical convention.

This is a thing in photography, with the lenses you can change on a camera body. The direction the rings turn to adjust focus, aperture, and in some cases zoom changes based on who manufactured the lens. Annoying to go from one system to another if you aren't used to that. And it also comes from proprietary pieces. The mounting system changes, how far away the lenses are from the sensor/film (flange distance) changes, mechanical and electronic linkages change. It's a mess. Be glad there is a standard that everyone uses, and there can't be engineering pressure to make it proprietary. Bottom brackets are annoying enough.

I enjoyed this discussion on a topic I hadn't thought about much, if ever. I had just thought the drivetrain location was related to nautical tradition. The starboard (right) side of a boat or ship relates to where the rudder was traditionally located prior to centerline rudders coming into fashion. Same for having the steering wheel and controls on the right side of the car (at least in the UK and most Commonwealth contries plus Japan and a few others). I hadn't considered bolt rotation or mounting a horse for battle in Arthurian times. Excellent video again from GCN.
