- The best brakes you can put on your mountain bike, but more importantly, why they are the best brakes you can put on your mountain bike.

I agree on the centerline rotors being 💩
Unconvinced, there are no mtb rotors that are actually floating (play in the rivets) and heat is not nearly as big of an issue. Al spider rotors are slightly better in terms of resisting warping but that's about it. If it were truly an easy performance gain you'd expect to see them in all of the big players' lineups (sram, trp, certainly galfer) and on every dh bike
The brand new SRAM centerline X are are floating. Well, to your point they are technically “semi-floating”
I came across some some rotors from zeno that claim to be more floating but is dont know enough to say that they are
the heat transfer to the carrier is wishful thinking. the contact area between the steel and aluminum is so small that the heat will just stay on the steel part. it might help against warping, but even that is questionable. I'm testing out cheap 203mm 2.3mm thick rotors made from a single piece of steel. The idea was to have more mass and more heat shedding capacity. not the case, and they warp pretty badly on long descents, however straighten back up once they cool down.
Stainless steel is a terrible heat conductor, and warps immensely (common knowledge in welding), so the only way I see to prevent warping is to keep the cool with airflow and/or water.
I used the hopes and the very cheap floating rotors you find on ali, both have way better results than ice tech or 2mm galfers.
If you're looking for another efficient option is going solid but with more mass and thickness, 2.3mm + but yeah these B are heavy 😂
I used to have centerlines on my kona operator but i switched them out a few months ago for that same pair of hope rotors and ive never been happier. They're way more grippy and so far i haven't had them run hot on me or squeak
The loosening of the bolts and squeezing of the lever helps sometimes otherwise once the pistons and pads are centred ….eyeballing is better…sometimes using a shim or two as well ☺️
you're right to use a shim ... ano brake instead of a S-RAM one. Or buy trickstuff stuff, if you have to much money. They are in a different league from everything shown here.
dont forget before you tighten the bolts to "pre load" the disk but twisting it counter close wise so the disk doesnt slip after everything is tight.
Great point!
The turbo levo I got has those centerline rotors, and honestly, they don't seem impressive, especially for a 200mm rotor. My front rotor also came slightly bent, so I've ordred a pair of the hope floating rotors, so I hope they make a difference.
You’ll love them. I’ve never met anyone who doesn’t.
@phoxrides I've got a question what type of material do you have on your break pads? I've ordered some for mine and the breaking strength has gone to literally 0. I took it to the bike shop and they looked at it and even checked for contamination but they're thinking it's the pad material
@@SubaruWRC1996funny enough I was planning on making this video soon.
Most MTB pads come in two flavors. Resin/Organic or metallic/sintered.
However a third style, popular in motor racing, is finally gaining popularity.
Stick around for the upcoming video.
@phoxrides Right now I've got sram, which had the metallic pads, and on the hope rotors they aren't doing anything. I took it to a bike shop, and they thought the brakes were contaminated it's that bad. Would organic pads make much of a difference, do you think?
Tried some ceramic break pads and just putting them in got a massive boost to power without even Bedding them in properly yet. Definitely think I've found my preferred break pad.
Magura MDR-P?
Trickstuff Dächle!
Stop touching the rotors with your finger tips
It’s not that big of a deal unless you have greasy fingers. Plus. Brake cleaner.
@@phoxridesIt’s the grease police 🤣🤗🥳
as he puts his fingers on the part of the rotor you don't want finger oils on... ;)
🤣 first thing I noticed. Too funny
Its not a big deal unless you never wash your hands. Or just ate a fried chicken. Plus a little brake clean makes it GTG.
grease police 🤣🥳
@@phoxrides doesn’t matter. You always have oil ‘s on your fingers.
@@pedallinraw ha.
Ive ridden bikes for 4 plus decades. Pedal as well a motocross and streetbikes.
Also have a ton of track experience on both street and track.
This is a wash. Bikes and even ebikes dont weigh anywhere near as much as a motorcycle and my KTM Duke is much faster in 1st gear than any either a bike or an ebike.
This whole comparison is laughable.
The hopes are nice discs but it is not the carrier that makes the different. I have 230 pounds naked and brakes are a big thing due to that. The big different is the thickness of the disc. Normal discs have 1.8 mm thickness. I kill this discs in one day. I am using discs with a thickness of 2,3 mm. They fit perfekt with hope v4 brakes. They are made out of one peace. They do for what they made for. Just braking perfectly. No squeezing or rubbing. Never had heat problems. My last bike is a gravel. There are only 180 mm discs allowed. Big problem. Normally I run 203 mm. First I mounted exactly the hope rotor that you are promoting. I run down with 90 km/ hour and had to brake down to 15 km/ h. I had a brake fading with loss of the front brake. The hope disc was blue do to the heat and dented. I changed the disc and now I am using 2.3 mm puncture disc from brakestuff. In 180. I tested the disc on same hill with same speed. No problem. More and more brands offer discs with more thickness. To save weight on discs is stupid.
This is a terrible comparison and shows a lack of understanding.
1. You are comparing floating rotors to fixed rotors-apples and oranges.
2. SRAM centerline X and XR are both floating rotors and used on pro bikes today, both road and mountain.
3. Shimano XT and XTR are also floating rotors and their Ice-tech technology are first class among enduro and downhill due to them being 3 layers, aluminum sandwich between 2 outer steel plates.
4. Floating rotors are not there to dissipate heat like you said, that is just a nice side-effect just like suspension on a bike is not designed for your comfort but for wheel tracking. A floating rotor is to allow the metal to flex under constant high heat to prevent warping.
5. You do NOT need floating rotors on your bike, motorcycle or car for good braking. 99% of vehicles purchased use a fix rotor design and they go much, much faster than any bike.
6. I can’t speak on the quality of Hope-they are popular-but both SRAM and Shimano use a coating on their rotors to prevent rusting which IMHO is more important because a contaminated rotor will not mate well with the pads and there diminish braking power.
7. Lastly, there are the pads and calipers to contend with so rotors are only one component of braking.
none of those are "floating" whatsoever
