I'm off to the Alps, do I need to upgrade my rotors to heat resistant one's or could I get away with standard rotors. I plan on using the brakes more than most as this is my first trip
Can you post a link to these heat resistant rotors, I too am going to be using my brakes and I am very interested also.
I'd suggest some appropriate pads first, and a full bleed of your brakes before the trip. Brake fluid absorbs moisture over time, and this lowers the boiling point of the fluid significantly, leading to brake fade.

Not true of mineral oil, as far as I know.
So if you have DOT fluid that is a couple of years old, a bleed would be good preparation.
Those Shimano Icetech rotors seem like what you're after - not cheap though.
' heat resistant rotors'
april fool right?
if the rotors dont get hot, the bike don't stop.
basic laws of physics.
I was just about to ask if this is a real question?
[i]april fool right?[/i]
What ?, on the 5th.
A few days late, No ?.
Probably blame DHL for the late delivery.
Anyway.
Is it worth while applying some heat conducting paste on the face that the rotor mates to the hub ?.
That way the hub gets some of the heat away.
I suppose the logical step from there is to have cooling fins on the hub, between the flanges.
Oooo !.
I think I've just invented the Alp specific wheel hub.

Heat Resistant Rotors? Do you mean Floating Rotors?
If you're running 160mm on the rear, an upgrade to 180mm would be a good move as you'll probably be dragging the rear brake a lot more than normal.
You might go through a lot of pads, I went through 2 sets, while others went through one set a day. 😯
guys
I was just asking as when I was looking to upgrade my present one's the different sites offer "new alloy" and "heat resistant" and when you investigate you can see the different priced one's are more heat resistent than standard rotors. I just want to stop when the track stops, its not much to ask
If you don't need/want to change the size, I would just ignore the marketing BS
I'd fit some 200mm rotors. Check your pad thickness often, it's amazing how quickly you'll wear them down if you're doing prolonged steep descents.
The Ice tech shimano ones are probably the best (if you believe the marketing) but i'd probably just get the £10 superstar ones.
ok great thanks, can I use any shimano pads or must I look for ice-tec pads?
"if you have DOT fluid that is a couple of years old, a bleed would be good preparation"
A bleed, or flush out all the fluid and refill/bleed with new bottle fresh fluid?
"fit some 200mm rotors"
But check your fork and frame are warrianted for them. Many aren't, and risk snapping
some older marzocchi forks were 7" max (180mm?). Most Rockshox (from tora up) are 210mm
Frames can be 185mm rear rotor max (some 160mm?)
The first question we should be asking are, what are your current rotor sizes, then what type of pads and finally what brakes.
Superstars pads are good value (you'll go through a few sets!!) - kevlar ones work well, so stock up before you go.
Bigger rotors offer the advantage of better braking through mechanical advantage but also greater surface area to disapate heat. Stick some big rotors on and you'll not regret it, but I wouldn't worry about whether they are the latest all singing all dancing models - the larger rotor size will make more of a difference than icetec or fins etc.
I always grease my rotors to stop them heating up.
Works a treat. My brakes never over heat even when i use them.
I find waterproof gease best as it doesn't wash off in stream crossings.
SSStu I presume you mean in between the rotor and hub (and bolts), rather than the braking surface? ..
~This thread is useless without winkfaces or sarcasm flags set to notify!
Take a few sets of pads and you will be fine.

I find it best if i grease the brake track on the rotors. Just the one side though.
Normaly the outside of the front rotor and the inside of the rear rotor or the brakes start pulling to one side.
I turned mine blue last week, do I need bigger ones now?
