I've got Rossi Race 140s (pivot series) with custom superwide Prophet 130 brakes, but could be bent straight and shortened, or what-have-you...I might let them go for the right price, pics can be found in my profile, PM me if you're interested.
I just got some FKS 155 online for 150 bucks, but they only came with a normal brake. I'm widening mine to 115, and I hear people have gotten them on 130's, so that might work. The brake arms are really long
yo, 150 is about the max on the wire heel, my boy from back at school had a pair of lizzie proto types that were 155 underfoot and we got p18's on em so yeah. shouldn't be a problem once you get them.
