With the PM-PM +20mm brake adapter you can increase your disc size by 20 mm.
This means, if your Post Mount (PM) brake mount on the fork or frame is designed for a 160 mm brake disc, you can mount a 180 mm disc with the installed adapter. The same applies to other disc sizes.
PM brake mount 160 mm + PM-PM +20mm adapter = brake disc size 180 mm
PM brake mount 180 mm + PM-PM +20mm adapter = brake disc size 200 mm
PM Brake mount 180 mm + PM-PM +20mm adapter + 2 spacers* = Brake disc size 203 mm (*With one spacer per mounting side with a thickness of 1.5 mm)
PM brake mount 200 mm + PM-PM +20mm adapter = brake disc size 220 mm
PM brake mount 203 mm + PM-PM +20mm adapter = brake disc size 223 mm
When using the PM-PM +20mm adapter, longer mounting bolts are required, which are not included and must be purchased separately. Item no. 01990
