brake disc adapter
#1
Okay building up a bike for the miss's to use and i dont understand this whole brake disc adapter iso measurements and things. In simple terms i got rock shox dart 1's and a promax (off the cheapest bike in halfords) mechanical brake disc mechanism. Had a quick look and there are hundreds and hundreds of different adapters ( well it looks that way to me). I was wondering if someone could translate my simple measurements into an actual useable termanology. I measured the mounting hole from center to center and on the rock shox its 3" and on the brake its 2" from centre to centre. Can supply pictures if need be. Any help would be greatly appreitated Smile

The two things you need to concider are

1) Is it post mount or IS mount..... post mount applicable only to the fork~ the holes look backwards. IS mount, the holes look sideways. The rear will be IS
2) Disk size.

Let us know what you have & we're offer more advice on the next step...

this is what you need:

but, as with all adaptors you'll have to go up a rotor size: your 160mm will have to go in favor for a 180mm
