Danger of accident due to brake failure caused by faulty installation.
Î – Use.original.MAGURA.brake.shoes.exclusively.–.they.have.an.important.
spacer,.a.correspondingly.longer.threaded.sleeve.and.screw.
Î – Use.only.brake.pads.that.have.been.approved.by.the.rim.manufacturer.
(for.carbon.rims,.for.example).
Danger of accident by bursting tyres.
Î – Make.sure.that.the.brake.pads.cannot.contact.the.tyres.

The.spacer. ( 2 ) .for.a.narrow.rim.(18–22.mm)..is.between.the.convex.
washer. ( 3 ) .and.brake.arm,.for.a.wide.rim.(23–28.mm)..between.the.
brake.arm.and.the.concave.washer. ( 4 ) . [ g2 ] .
