Freewheel, Horizontal Rear-facing Drop-outs and Rear Disc Brake

hippy Good for trials though, when you don't actually need modulation.

yeah. that's what i was thinking of.
used to have a little bash at trials and thats what all the kids use as you can't run a rear disc on a trials bike without ripping the frame apart.
they look pretty sweet as well!
tbh, avid v's are almost as good.
