You can work harder in an athletic stance w hips hinged. So you can't get in that max power position w that thing.

Wanted to know if anyone has one of these, and if so, do you think it's a bad idea to stand and pedal versus staying seated? I don't want to kill the bike chain or anything like that. I can't seem to find that question answered online, so I thought I'd ask here.
