Whats this to do with retro i hear you ask.

I have pair of early hope 3 bolt rotors and spiders i got on ebay a few weeks ago .Each slot on the rotor is elongated and are mounted on the spider by way of a 2 piece bolt system with a large spring steel compression washer on each side. As far as i can see this must make it a floating rotor :? I think they are '94 or thereabouts.
When they arrived in i thought the bolts and their carriage system was some sort of 'beefing up' but looking closer saw the rotor was mounted on the washers which were there to give it about a 1mm designed play on each side :?
Ill post pics up tomorrow to show. Begs the question :? Did the early design come directly from motorcycle brake rotors or are those bolted on firmly the way ours are :? Anyone answer that ?.


This obviously has a knock on thought

You know all those 5 bolt rotors you have kicking about :?


Should be followed by, Aha :idea: :wink:

Motorcycles come with both floating and solid rotors.

Righto
But was the technology originally floating or at that time did they only that to base the model on :?

Floating bike rotors since the 1960s. Floating calipers are easier and cheaper, or even opposed listings where nothing needs to float.
