I’ve had mono mini’s, X2’s, XTR (older), XT (newer) and Avid Elixirs (various versions).
The hopes I was running with 140/160mm rotors even though I weigh 100kg. They were barely an imporvement on V-brakes but that’s all I wanted. Ditto the X2’s.
XT are great if a little grabby, not much more outright power than the Avids though, it just comes in one big hit.
The Avid’s are fine when they work, but getting them bled properly can be a PITA. I’d accept new ones on a bike, on the basis I could keep returning them untill they worked! But I’d not get them aftermarket.
I’d save all that money the Hope’s cost and get shimano, they’re just better.
Although at the moment I’m starting to want some even stronger brakes on the fat bike. You can hit corners at frankly terifying speeds which them means you’re not going the speed the trail designer intended you to be going and sudenly need a lot of braking power from those 180/160 disks, and with 4″ tyres even a 160mm rear disk is capable of doing alot of braking! Heck even on a normal bit of trail the grip allows you to brake after the last braking bump without losing traction!
If you want bling brakes, get Clegg’s, they make Hope look like they fell out of a cracker.
