Perfect fit
Upgraded to a larger brake rotor on my ebike. This adapter fit perfectly and the alignment was right on

Easy upgrade
I bought this to upgrade the 180mm rotor to a 203mm on my fat tire ebike. The fork tube was set up for a 160 and was using a 20mm adapter for a 180mm disk. I removed the 20mm adapter and installed this in it's place, for my new 203mm rotor. Quick and easy to do, now I have more stopping power and better heat dissipation. Worked so well I bought another one to upgrade my (human powered) winter bike.

For 203mm rotors, not 200mm
This (even the black color, not just the matte black) is for 203mm rotors. My pads definitely overhang the rotor just a little bit and while it works short term, I've ridden a setup like this in the past and you WILL lose brake power when the pads wear ridges into the them and the unworn slivers no longer let the wear surface clamp the rotor.

Works
Hopefully this will help fellow mtbrs. This is a 40mm spacer. It is not 40mm thick, it is offset to give you the space you need for a larger rotor. If you have a 160mm rotor and don't already have a spacer this will let you mount a 200mm-203mm rotor. If you have a 180mm rotor and no spacer, this will let you run a 220mm-223mm rotor. You can check your bike specs to see what your mounts are. You can check you fork manufacturer to see what those mount specs are.

40mm not 40mm
Ordered the 40mm adapter. To mount a 220 rotor instead of a 200. Was about 20mm to short

You’ll need shorter mounting bolts than the original set on your fork
180mm shimano to 200mm sram on rockshox pikeThe short bolts it comes w/ could be used to mount the PM to the fork or if you have a set of short bolts that’ll work too bc the original bolts that are holding the brake caliper are too long. Outside of that it seems to fit pretty well.

Perfect fit and function
Made a big difference changing from 180 to 200mm rotors. This spacer for perfectly

Does not work for 200mm rotors
Nice product, but this is not for 200mm rotors, your pads will overhang the rotors if you use these. Description is inaccurate saying it works on 200mm.
