I am woundering if freezing the endcap would have a best result because ice can contract de metal and turn it loose... hot water dilated the metal turn it even more tighter. But for you heating the metal turn it loose... how come?

Great info thank you

Thankfully Fox (at least used to) build their products with quality materials, including details like the small bolt that holds the retainer plate in place. Even so, before threading that back in, apply some anti-seize compound (lube) to its thread. This to reduce the risk of having the thing stuck in place and stripping it out when the time comes you need to remove it again.

On the website they say some pegs can't be lowered 40mm, do you see any reason why not?

Brilliant thanks

This was soooo satisfying to finally get working again. I had watched another video which was really great but this had a few extra key bits of information. The plastic cover going under the washers, and showing how the bolt and cover over interact and tighten up too far to restrict the lever. For me the little plastic external twist bolt thing was so lodged into the inside bolt it all came out as one and I think this was the original cause for the lever tension being too great. But for the life of me, I couldn't undo that plastic cross shaped bolt out of the lever by itself. I needed vicegrips to remove it from the inner bolt in the end! And then reassemble. Thanks so much for making such a detailed video. Getting that crisp click back is so good.

Just got a bike with the RS4 hub in need of new bearings to remove a bit of slop. Very useful video and good to hear what I suspected, that Pro 4 bits are interchangeable. I can’t find a seal for RS4 but loads for Pro4 ……… now starting to think about increasing the number of pawls too…😂

I was considering to put the same bearing also on the blade, where the bite point adjust is, it has a bushing as stock, i think with a bearing it will be even smoother don't you think?

Thanks for this video boss man 👍 helped out a lot with my bent brake lever

Ottimo bel lavoro

Hi, is this for Sram or Shimano Kassette, cause I thiught my Kassette is from Sram, but in another Video I saw this is shimano Hub… 😌

Can I remove the free stroke screw without removing all the parts?

Thank you for the step by step. I could not figure out how to disassemble to replace the seals I had ordered. Fingers crossed that is the problem

Great clear video. Any knowledge of using the braided hose with Shimano components? Hope sell a type O set with "all the fittings", but I can't find instructions. There's a connector with a cone-shaped end that looks like it goes into the lever/calliper and leaves the appropriate end sticking out for the shroud. I assume this just gets screwed in and then the rest of the connectors used as normal?

Does the tech 4 levers fit the tech 3 master cylinders?

I have a RAIN.RDY Adidas cap as well. Going for 3-4yrs. Washes well and fully waterproof.

Thanks for this thorough review - about to buy some but 0.5 up so 11.5 for me as the 11s were a tad on the narrow side. Tried the UK 11 on in SportsDirect today. Will change insoles to Slazenger Pro Gel when they arrive. They are £49.99 at time of writing this on SportsDirect website

does this same "flex" occur on the Tech 4 V4?

Thank you for this Video i was looking exactly for this, now i know where to put the small bottom ball bearings!

Excellent tutorial! I have a Giant Cross City bike and that has a freehub that is accessed on the left side (through the wheel) not on the right through the freehub. The locking nut takes a 12mm Allen key (I used a Kinchrone SCMV 12 100mm long, 1/2" socket) and turns to the left to release for those unsure of their setup. The bearing race on the left side prevents the freehub lock nut from being removed without removing the race itself, which I didn't bother to do. Bike mechanics say Giant are notorious for over-tightened free hubs, but it came off easily using torque from a longer socket wrench or pipe as per the video.

I have V4 Vented rotors on my Tech 4 E4 brakes.

They say you can not put V4 Vented Rotors on E4 brakes. But i have.

Great video as always. Amazed there is so much flex in a solid piece of metal! But, there is no way I can get that much lever throw after the bite point as you have. Maybe I have weak hands... lol. But seriously, no way. That said, I struggled to get a solid feel on the rear brake, but after a few bleeds and careful alignment, it is very close to the front now which is super solid. On the trails I love these brakes, but they are a huge hassle to set up reliably and take an age to bed in and settle. I really wish they had a bleed port at the master cylinder instead of the lid, as often I got a good bleed and then it messed up on putting the lid back on.

Yeah, same story with mine, if you push the lever really hard the caliper flexes a bit. I didn't get it on camera, but it seems to feel it with fingers, if squeeze the caliper with hand and push down on the lever. With V4 the situation seems to be better, it is more monolithic. But even with E4 I don't see any problems, because even with a lighter pressure the rear wheel is already locked.

Can you take a still picture of the spring orientation/placement please?

I had issues with my 1st pair .caliper leaking at piston. The second pair developed a faulty lever felt like it was grinding. I really want to love these brakes but I just can't .

My levers move just like yours even after bleeding them loads. They seem to work well just no solid end to the lever pull. They are always noisey too 🤦🏻

Hi! Where did you get all the tools and from wich brand? :)

Thanks for the video, helped me a lot to service my Bulbs!

did you not have a circlip inside the freehub??

Thanks for this! Just for info my 2024 Hope braided hose kit type 2 (non-universal) came with only one line on on the shroud. Haven't tried to fit yet but it fit easily over the uncut hose & was all part of the same kit.

Thank you for making this video. You gave me the confidence to put my cassette back together by myself. My bike is back in action thanks to you!

Rain.Rdy, Gore-Tex and other PTFE membranes are functionally identical. The technology is no longer patented, so there is no reason to overspend on the branded shoe. The one difference is how stringent GORE is about manufacturing techniques and the requirement to send the item to GORE for testing.

Não vale a pena retirar o castelo do freehub do cubo, pode-se fazer a manutenção sem retirá-lo, fica até mais prático.

How is the fit?

Subbed! Great video mate, very informative, I'm about to do a quick service of the free hub and thinking about using Chris King oil instead of grease and only on the pawls, I like them loud too :)

Great review 👍🏻 I did check out a few reviews seem to be pretty good so I brought some today now I've just seen this Great gonna wear them for a month or so and if they start falling apart i will take them back and pay extra for a decent pair of boots. Can you recommend anything for around the £100 Mark which will keep my feet dry 👍🏻

Great video. Exactly what I needed

What about XCR PRO version?

Great video thanks! Helped me a lot so far but still need to order some tools to get the bearing press over the thru axl. The sockets at 23:50, where did you order those? Or how are they called? Are they specifically for hubs or just some custom tools? Thanks!

nice review

Dismantle spokes, service and then rebuild wheel. No thanks, just buy new again.

is there a way to shrink it again?

Thank you, great

I have the same hub and the top cap on the freehub body on mine is very loose, would come off with no effort at all. Am I missing any rubber bushings i it? Thanks.

Did you ever work out the source of the axle play? I have a full wheel with one of these that has some axle play even when assembled and on the bike. Sounds like yours is only with the end caps removed?

Thank you so much for this - replacing mine soon so it's great seeing what tools I need and how to do it! The local bike shop said the hub will only need 2x 6803, thank god I found your video...

I have a rain rdy "my shelter" jacket and you're right it's very much like goretex inside

24:26 Why not press it at this point with that extension bit?

4:30 Correct me if I’m wrong, but doesn’t this design require full bearing replacement because the axle ridge (?) pushes on the inner race during extraction? Maybe just one side because after pushing the axle out in one direction, a proper bearing extractor could be used for the other side.
