For Sale Mega Rare Prototype Front Shimano HRB Roller Brake DH Downhill Retro Vintage

[heavyp]

As the title states I have for sale a mega rare prototype shimano hbr dh front brake and hub.

I have heard only about 30 of these were made and they were tested by limited DH riders (I am unsure if they made it into XC racing/testing)

The brake includes the hub, locking ring/nut, cooling fins and the actual brake part itself with the braking shoes, I can also throw in a spare set of shoes

I do not know to much about these only front what I have seen in articles and the riders commenting on some social media posts but what a cool peace of kit it is.

110mm front with a 20mm bolt thru axle.

They didnt come with a bolt for the brake cable but from what i have seen they just used a normal nut a bolt for this.

Everything seems to work, and it is in great condition.

Location: Australia

Price: $750USD £550GBP $650EURO

Is that basically a drum brake but for bikes?

"Sheldon" calls them a drum, but that's incorrect imo, as it's a clutch brake, significantly different, and not using a drum-style Friction surface.
When they were more common, they are usually referred to as a roller clutch brake in the UK trade.
