Vintage hydraulic brakes for canti posts. Very nice Magura HS22 matching brake set. If you want some positive winter braking power you need these. All orig hardwear is there to run the boosters or the other bolts you need if you don't want to break your chainstays, They are adjustable for any size rims on canti posts. I would suggest the thickest rim possible these are very powerful brakes. They are a little tricky to set up {have included 2 extensive brochures on installation and service} but once they are set they are very low maintenance have included spare pads/fittings/hose blocks and the braze on fittings for the hose routing. have at er!/ $120 can + ship
