Genuine shimano part
Perfect item for the job. Previous 20mm spacer required some additional washers to use with my 23mm rotor, this fits perfectly and does not require any other washers. Genuine shimano part.

Much better than the ones provided with shimano brake kits
The materials used don't corode as fast as the standard mount provided with brake sets.

Genuine XTR
I had no idea they made XTR versions of the caliper mounts having brought loads of standard mounts. The difference is obvious straight away weight wise. So being a bit of a weight weenie, I'm very happy.

Great price for a genuine shimano 180->203mm rotor adapter
Genuine Shimano adapter - noticeably light and strong, with bolts and wire fixing (I used a plastic fixing clip, though).

Does not work with a 203mm disc
Says it works with a 203mm disc but it doesn’t. In fact it not much different to my 180mm mount.

Este adaptador lo he usado para colocar discos de freno de 203mm en una suspención FOX Factory 36 2021. No necesitas espaciadores ni nada, solo lo colocas y ya esta listo para el disco de 203mm. Viene con sus tornillos y rondanas. Prové algunos otros de menor calidad y fue una perdida de tiempo, este es el bueno!
