>>952634Idk it's not really catching up as a trend, it was pushed a little and KINDA took on for some downhillers, but most people will run anything from 700 to 750, 800 is just absurd.
Myself, I've got an older MTB so it has a 600mm bar with a fucking 100mm stem. It feels okay but I'd really really like to switch over to, say, a 35 or 50mm stem and a 700mm bar. I don't feel like I can move back enough with such a long stem.
