You saw this type of brake system on a few custom motorcycles. And you thought it was beautiful and a good way to show your custom wheel. In single or dual version, front or rear wheel, they are not available as a complete kit from your favorite wheel vendor.
So the perimeter disc brake rotors you saw were installed by the builder. Maybe some will want to launch a debate in “comments” about the unsprung weight advantages versus the higher gyroscopic and braking forces generated from a wheel with a rim fitted disc brake, but the main purpose of this post is to introduce you to what I think are the first pre-assembled perimeter discs on spoke wheels. And since this company is HD Wheels with a lot of spoke pattern offerings and colors (rims & spokes), you just got many more options to customize your bike. Perimeter discs available on wheels from 15″ to 21″. Contact Andrei Rybkin on my behalf at 818-887-9065 or visit HD Wheels.
