Hope floating rotors
 

Anyone using Hope floating rotors on their road bike ?

Yep, I have a set on a Specialized CruX.

Yep. Just bought a second set. They work very well. Worth the premium price.

In what way? Do they stay truer than the Dura Ace, for example?

Both of DA rotors I received came out of box wobbly. I don't remember seeing that with my other rotors, Shimano or not. Does floating rotor squeal less?

They look neat.

Waiting for their Carbon Centre rotors to reach the market.

Has anyone encountered the issue with rivets fouling calipers? If its not too bad I'd think this could be addressed with careful filing/grinding.

Had the button-fouling issue on my MTB (Saint brakes) careful filing did make them not contact caliper, filed some width from side of post mount on caliper itself.

Not impressed with the floating feature, couldn't say it helped with heat management (disc warp/rub) funny because I really believe in the floating concept, having spent a big portion of my life in the motorcycle world.

Hope Rotors
 

Are they prone to less warping than OEM rotors on long descents?

I used Shimano rotors for a while, excellent performance but mine would come out of true.

Switched over to Galfer Wave rotors. They have been flawless, and have yet to cook them or ever needed to true them. Running the Road Wave 160/140 on the gravel/road bike and the standard 160 Wave rotor on my MTB.

Not really for me, had the rear rotor warping after big descents/a lot of heat. Straightens right up after it cools down. Really most rotors will do this if you get them hot enough (not just Hope)

If I could suggest anything it would be go larger, couldn't be happier since I switched to 220mm (MTB) front and rear.

Something I find interesting:

A lot of rotors will get hot/warp then cool/straighten, the "heat up/warp".

In my own experience I've found rotors that need truing/get trued do this more than rotors that come straight out of the box.

I chalk it up to internal stresses in the rotor that accumulate from bending/truing.

I'm sure someone like MarkMCM can try to explain this a little better.
