>>2010684red dot is the pivot point of the lever
other dot is the cable anchor
aero levers pull the cable out rather than up which gives them more leverage.
That's why they caught on. At the start they were considered garish and annoying to work on but the increased power was undeniable. That's the reason it's so stupid to use them, especially with cantilever brakes supposedly being ridden offroad and touring, which need all the power they can get. I mean i have some on a beater but on a $4000 'serious' bike is just bananas.
>>2010685i know what cable pull ratios are but i don't see how that is relevent
>Tight bend are a non issue made up by vintage fags.cables are the exclusive domain of vintage fags now. your silly internal routing is just fine with hydraulic hoses and electronic wires.
