It looks like there are disc tabs on the fork, what about the rear? What axle sizes does it run now?
Tempted to turn this into my semi-trials dirt jumpy kinda thing. Or maybe 650b if the rear has enough room.
It used to have discs front and rear so you can definitely install them. Right now it just has bolt on cruiser wheels but I've always had regular wheel with quick release clamps on there prior to this setup
