Run a bigger rotor on a post-mount frame or fork without changing your caliper. This SRAM post-mount disc brake bracket repositions the caliper outboard by 20mm so you can step up to the next rotor size for stronger, more consistent braking.
Highlights
- +20mm post-mount caliper adaptor – mount a rotor one size larger than your frame or fork's native post-mount tabs
- Black finish to suit most calipers and frames
- Supplied with stainless steel mounting bolts for corrosion resistance
- Genuine SRAM original-equipment part
What it does
A post-mount (PM) caliper bolts directly to the frame or fork tabs for a set rotor size. This bracket sits between the caliper and those tabs and shifts the caliper 20mm further from the hub, letting the brake pads line up with a rotor that is 20mm larger in diameter – for example stepping a 160mm post mount up to a 180mm rotor. A larger rotor increases braking leverage and helps shed heat on long descents.
In the box
One post-mount disc brake bracket and stainless steel caliper mounting bolts.
Fit and compatibility
Designed for SRAM and Avid post-mount (PM) disc brake calipers fitting to post-mount frame or fork tabs. It is a +20mm bracket only – confirm your frame/fork's native post-mount rotor size and your intended (20mm larger) rotor size before ordering, and check the brake manufacturer's caliper-mounting specification for your exact rotor. Not for use with flat-mount or IS-mount calipers. If you are unsure which adaptor your bike needs, get in touch with us before purchasing.
