I'm just about to combine the two for the first time and it occurred to me that it's not something I've seen very often - if at all. My Loops are currently on my (rigid) fatbike but that'll likely get parked up over the summer so now is the ideal time to try it.
just got a bike with front suspension and put a spare set of jones bars on it.
seems to be pretty much the same TBH, i run them a little bit flatter but thats probably because the stack height on the new bike is lower than it is on the jones plus i have and i want the ends to be well within reach.
drjon does it. I'm sure you'll be fine. Or at least you certainly won't die.
my experience is that the loop bars work best with no weight through the hands and with a really light handling front end - you get less leverage with them y'see. This is the polar opposite of how a modern front sus bike is designed to be ridden.
How technical your riding is and how useful being able to shift your bodyweight forward and backward during everyday riding is, is probably going to be the deciding factor of how well you get on with them
