if there’s marginal difference in weight what benefits have one type over the other.

I know floating ones look nice and tarty 🙂

Floaters go “ting!” when cooling down.

Supposed to be better heat dissipation from floating I believe.

I’ve never noticed any practical difference. But they look nice.

They just look nice – no need to try and justify it any other way imo 🙂

Floaters go “ting!” when cooling down.

for that reason alone 😉

Agree with the above. Meant to be lighter plus better heat dissipation but everyone knows that in reality it’s because of the bling. That’s why I bought them

There’s more to go wrong with floating rotors – I’ve had two Hope 160’s go decidedly wobbly at the rivets, and a third ripped apart when I hit it on a rock (not that a normal rotor would have survived that, but it might have been straightenable).

only asking as can’t run floating disks with king hub on fox post mount forks so it’s rebuild the front wheel or use solid disks 😥

Why couldn’t you running floating discs? Surely if they have a standard 6 bolt mount you can run them on anything.

its not that the floaters have better heat dissipation – they don’t – its that they will not warp when very hot as the floating bit allows them to expand

Doesn’t the alu centre have a greater heat capacity and greater thermal conductivity than Steel? That should in theory deliever a benefit…

That said i’ve not factored in the weight difference of the alu vs the steel so there either a) may be nothing in it b) be unmeasurable in practice.

A floating rotor should be lighter tho shouldn’t it?

Mine didn’t have any performance benefit, but were a wee bit heavier than standard steel (everyone thinks they’re light, but not really the case with Hope) and they didn’t fit well in my calipers. Well rid of them tbh.

I think some calipers clip floating rotors (the rivets), so just be aware of that & check for clearance issues.

Hi

I have a hope floating 160mm rotor on a king hub with a fox post mount 29er fork.

No problem.

They can clip certain callipers – obviously not Hope ones though.

The alu may well transfer heat better, but the rivets would probably cancel out any gains.

Aluminium rotors

who’s doing aluminium? kinda makes sense

aluminium is a rubbish material for getting good braking so needs some sort of surface coating – making it expensive and short lived

Aluminium is the material it can be done with ti also and carbon

The alu may well transfer heat better, but the rivets would probably cancel out any gains.

More than – the heat transfer across those will be awful due to the discontinuities.
