Hope Technology CNC machined mounts offer precise fitting to most frames and forks.
Take a look at the selection chart below, there are a couple of notable mounts. H and K are the adaptors you need if you want to fit a larger rotor to a 180 post mount (H for 200, K for 203)... Your welcome ;)
NOTE: 180, 183, 185, 200 & 203 diameter brake discs.
Over the years there has been some confusion over these 'middle' sized brake discs. Although Hope will continue to manufacture 183mm discs and their corresponding H and J mounts, they have decided to standardise on the more common 180mm disc size
Post Mount tab position varies depending on the manufactures intended minimum disc size. Pleas contact your fork or frame manufacturer to identify the Post Mount standard being used.
For future proof assemblies preferably use the following disc sizes:
140 / 160 / 180 / 200 / 220
