What is required to change the standard 36T ratchet to a DT Swiss with more POE? You mentioned a DT Swiss tube insert was needed over the axle in a previous video?

What about Fig2 on picture. This looks like mine adapters from 160 mm up to 180 mm and up to fi 203 mm OMG!! In Gazelle S8 ultimate. I recommend you brake discs from China. I bought two of them with 2 mm, and they work perfectly, and are 4 times cheaper than big brands with huge margin on this product!

I have M520, M8100 and M9100, the latter the best 😎 👊🏻 as always is Shimano XTR

Shimano s pre load and installation is just vastly superior

My wife's bike was supposed to come with SRAM DB8 4 piston brakes, but I was happily surprised that it came with Dominion A4's. The cross hair alignment screws are really nice. I wish all brakes had them.

My Oggi Razzo e-mtb has this U6000. I ride about 1200km with it (750 miles). It is really slow to hard gears. And, in several occasions after rain and mud the bigger light gear do not goes down more. I need to stop and press by hand turning the pedals and lifting the wheel . A strong spring is necessary for use in MTB.

I have A4 on one of my my bikes. They are awesome.

Once again trying to push Chinese junk parts. Unsubscribing.

Bontrager rim strip is really bad when trying to fit a DH tire. Middle channel on the strip is to small

Great videos! You let me have special idea. Would you have tested sram x1 11 speed shifter used with shimano M6100 12 speed derailleur? It works?

Hello, is it normal for the Derailleur to have lateral wobble (left right) when I undo one full rotation from snug? In every video it seems like it just becomes loose and pivots around the axle, however mine wobbles side to side too

Is that derailleur compatible with the regular GX eagle cassettes?

The black paint on the XTR version is for even better cooling 👍🏻 heat dissipation paint

Hola se puede colocar un plato genérico más grande para reemplazar el 32 original?

What about taking the bleeding blocks off the caliper? Don't you need to add more mineral oil once they are pushed out to the thickness of the rotor?

How can I know if this is comparable with polygon d5?

almost all trails here in nor cal are hard packed dirt, gravel fire roads, i use rekon race 29x2.4 rear and aspen 29 x 2.4 front

I had the MY800s on my road bike and found them constantly noisy. I moved to the CT800s a few months ago and have found them much quieter.

There are minute differences in performance between the two (400 and 500). Get the SLX levers to the 420 calipers and you have a great, money-saving system. When you have 4 digits to go for trickstuff-stuff, you will notice a clear difference :) But then, those trickstuff brakes put 99% of the braking systems out there to shame in terms of stopping power.

I’m the factory I certain the holes in the frame are drilled, anyways.

These are very common here in the Rockies and for a very good reason. The stopping power is excellent and it has some of the lightest lever feel. Just installed a set for someone recently.

Not extra 50% price of XT

I am running the A4 on one of my bikes. I like the consistency of the lever feel and modulation. I really like the alignment screws on the calipers. Makes it easier to get the rotor/pad spacing dialed in. Fairly easy to bleed as well.

Hi, you gave the best tutorial video on T-type shifters. I'm a new comer to the channel and staying tuned always. Thanks, best regards from Venezuela

I have the old, mechanical, cable actuated CX Expert disc brakes from Hayes on my cheap gravel bike, paired with the old mechanical Apex brifters. After changing the cable outers to the compressionless KEB-SL from Jagwire, these brakes are quite good, especially with sintered pads. Oh, and I've don a DYI upgrade by drilling and tapping the holes in the caliper mounts to make the Cross Hair Alignment System myself (transforming them to the Pro version, which was significantly more expensive). This system really works, it helps a lot with the alignment. Anybody, who is technically inclined a bit (and has access to drill press and know how to tap a small thread), can do it on any brakes, it's really worth it.

Im looking on upgrading to A4s coming from Code RSCs. Never had an issue with DOT fluid. And love the fact that I can get one from my autopart store 5mins drive instead of waiting for 2days ordering from amazon.

I've had Shimano, and TRP Slate Evo's, and don't like either. The Shimano's have good stopping power, but terrible modulation. The TRP's were weak, and the bite point kept shifting, even after multiple bleeds, I had to constantly adjust the levers. I just switched over to Hayes Dominion's about 2 months ago, and Goodness Gracious Great balls of fire!! They are amazing! I weigh 210 lbs, and they have no problem stopping my fat butt on the trails! The icing on the cake are the modulation, and very light lever pull. I have them set up to use just one finger, and I can lightly feather the brakes to slow myself down with ease. They were expensive, but, I am extremely happy with their performance. I'd say they are probably the best brakes on the market.

Can you install the bronze levers on the T4 version?

Group set

I bought a set on ebay and returned them with great prejudice because quality of manufacturing was soooo bad I was sure they were fakes. Yrs later talking to other people apparently they are just that poorly finished... Shame.

Hayes A$ brake on the front Sram Guide RSC on the back, full day shuttle riding. Got serious muscle pump in my rear brake hand meaning I couldn't use it at all front brake hand went all day without issue. Bought a rear to go on my full suspension and have a set of Jimi Hendrix brakes to go on my hard-tail. Run 200mm TRP thick rotors on both bikes.

I've been running the 27.5 rear trail endurance on my Bronson mullet for 5 months. It has shined in wet muddy conditions all the way to dry loose summer conditions. This is my first deviation from Maxxis Assegai in quite a while. It is very grippy, burley and predictable. I will buy this tire again! It is now very worn but still rides pretty well.

Mineral oil brakes have jet lag the winter.

Those alignment grub screws should be on every brake. Could you measure the thickness of the mounting tab and the diameter of the socket screw? I may have to add my own to my Magura

You might want to mention the Hayes D series rotors. My friend has the heavy ones on his eBike with 203 rotors. He’s over 300 pounds and his bike is heavy too and he has never had any issues with them.

Have review the hope brakes? I am only running shimano xtr brakes and code. And now the sram maven, and the sram maven are powerful. It did take me about 4 full bleeds to get the rear sram maven to work as expected. I do hear the shimano saint brakes used by the pros (saint caliper with xtr handle) are a good choice. I just ordered them and see how they work. The only con to some brakes is not every shop will have part for them which is unfortunate. I do like the hope.

The bronze aluminum brake lever looks so M🤘CH cooler than that boring looking carbon one🤘

These are what pro trials riders use. That speak for itself.

I have A2s on a trail bike and I love them. They are way more powerful than I need but the lever feel is so nice compared to Shimano or SRAM. The other comments about th quality of the fit and finish of the caliper are accurate, but so far they have 100% fewer leaks than my M7120s 😂

Coming from slx 4 pistons and got this A4 since 3 month, night and day with 2 dominion rotors (220 front and 200 rear) on my commencal tempo. Love this brakes, yeah now little bit old but still powerfull and so sweet on the lever. A nice brakes with the best of sram and shimano in my opinion !

Did you notice that on both brake calipers, the two sides don't actually sit correctly!! Kinda makes them look odd!! Not saying they don't work great but for the price you would think they could make a better looking fit!!

Great video but it already needs an update to cover the newest dampers.

Those are proprietary pads, right? You can only use Hayes pads for those brakes?

Nice looking and about the same price as XTR 4P.

I'm divided between these and Shimano Saint, anyone can give input between the two?

I have a set of T2. The ti bolts for the rotor are a nice touch. Setup is harder because the piston stroke is shorter than Shimano so the pads sit closer to the rotor. I put on 2mm rotors to reduce the chance of them getting bent. One con of the carbon levers is their fragility. I put a chip in one of mine when the wind blew my bike over.

So I bought these brakes after I bent the lever on my new SLX brakes after a slight hit. They stop really well, but I had some issues with them: 1. Not a fan of DOT. 2. Build quality of the caliper was disappointing for the price, the two pieces didn't align well and frankly it looked cheap. 3. I had a realy hard time while removing the screw that holds the brake pads in place, it was super tight and I almost stripped it. 4. Pad standard not same as Shimano, fewer options and higher prices. 5. The worst problem I had with them was that my right lever developed a crack where the bearing of the blade is attached to. The aluminum there is very thin and somehow it cracked without any hit to the brake lever. After that I went with TRP and I'm very happy with my choice.

Got to swap out the battery on derailleurs though..

My bleed nipples just leak all the fluid out when I brake after bleeding. Exact same issue in both front and rear. Very frustrating. Yes of course I tightened the nut again..

Are these components available through any other sales channel than dubious online platforms? Where do you get replacement parts from? What about warranty? Where do you have them maintained and serviced? As nice as these parts may look, there is no support infrastructure for them, and you are completely on your own when it's about making them work and to keep them working as intended.
