Swoofty Posted September 5, 2022 Report Share Posted September 5, 2022 Is it better to have the rear cog near the spokes or near the frame? In a lot of single speed applications we have the option of placing the rear cog nearer one side or the other, assuming the rest of the chainline lines up, but is one better than the other? I usually try to put mine closer to the spokes in the belief that it's closer to the driven part and reduces the lever arm on the rear axle, but I've got a bachelor of fine arts degree on the wall and not an engineering degree. Anybody got a more authoritative answer? Cheers Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted September 5, 2022 Report Share Posted September 5, 2022 From an axle fatigue point of view, nearer the dropout. I think, when considering the hub / rear sprocket, it more depends on the bearing layout and design of the hub. Overall, I tend to let my front sprocket decide where the rear one goes. 1 Quote Link to comment Share on other sites More sharing options...
DYAKOV Posted September 5, 2022 Report Share Posted September 5, 2022 Similar to you, I’m a 3D designer, so I’m probably speaking out of depth here but I think that stress to the axle caused by the offset of the rear sprocket is irrelevant since the axle is fixed with a bolt/ snail cam (or a vertical dropout design). That would be the case if the axle was hanging in the air on that side. Quote Link to comment Share on other sites More sharing options...
