Freehubs are an integral part of any standard mountain bike and without them, we'd all be cycling around on fixies! So, in this video, Doddy takes a deep dive look and tears down both a standard non-branded hub & freehub assembly and the Industry Nine Hydra hub to show you just what's inside each of them, how they compare, and how they actually work!

Spoke threads are NOT cut, but they're rolled on. It's effectively just cold forging. Material is not taken away, it's merely moved about. I even have a spoke cutting and rolling machine at work for trimming spokes to size, the spoke is rolled between two dies using a big old lever and presses the threads onto the spoke like butter. It's also much easier to replace a spoke on the go if the tyre doesn't have to be removed. Great benefit for all you tubeless junkies. ;) Also, these hubs are nice and all, but there's two things often overlooked with an inexpensive Shimano hub. Cup and cone bearings take much better lateral loads than cartridge bearings, and forged hub flanges are much less resistant to cracking than CNC machined hubs (again down to that "removing material" process involved with machining). For the most part it just doesn't matter anymore though, but I've seen a few boutique hubs fail just because they were trying too hard to be exotic.

@stormeporm Год назад

How do you know/see that a flange is forged? Do all shimano hubs have forged flanges?

@paulc.7487 Год назад

hi, hub bearing are not supposed to take lateral loads, on a bike unless you crashing the force is always perpendicular to the rotation axis of the wheel

@Metal-Possum Год назад

@@paulc.7487 Ever been around a corner? Ever been out of the saddle tugging aggressively at the handlebars during a sprint? Ever ridden offroad on rough terrain? Ever seen somebody on a BMX at a skate park? Hubs are subjected to all kinds of lateral loads regardless of the type of bike or where it's ridden. You can't just say they not supposed to take a lateral load, because they're always going to be subjected to those loads whether you like it or not.

@Metal-Possum Год назад

@@stormeporm Shimano have always forged their hub shells. They've got the tooling to do it, which makes the cost and time to produce one hub much smaller than any competitor using CNC machines etc. It's also more difficult for smaller brands to imitate them as the initial outlay of the tooling to forge hubs is considerably more expensive. This is also one of the main factors to Shimano using cup and cone bearings, the tooling is relatively expensive so that smaller brands can't replicate it.

@richardpowell5306 Год назад

Spokes such as DT Swiss, Sapim & Pillar do NOT have cut threads. They are rolled threads, formed from the body of the spoke. As a result of the forming process the threads are slightly larger in diameter than the body.

@redtobertshateshandles Год назад

I thought all spokes had rolled threads. Maybe not.

@stevenconnor4221 Год назад

There are engineering design reasons for everything. Rolled threads as said will be work hardened ( but they can also be annealed), you can cnc cut or manual lathe cut threads ( I have done many) you can then temper the material to suit, so no difference between the rolled threads. But sometimes there are different design reasons for having more pliable and even less stronger threads in order to break first therefore protecting more expensive parts. For example.

@RJ_Groot Год назад

I love my i9 hydra engagement. Just be sure to stay on the cartridge bearing maintenance and check or change them regularly. With the precision and small tolerance of the pawl/drivering any bearing slop will transfer largely into the pawls. Mine started making a strange noise so I immediately tore it all apart and found the brake side bearing had some wear. New bearings and good to go again. Love the sound too.

@dudeonbike800 Год назад

That's the problem with obsessing on engagement points - you're relying on ONE pawl's engagement to carry the torque loads. Since it's not distributed through three or four pawls, it tends to want to move off-center. Any bearing slop only exacerbates the problem. I really don't get the obsession. I want good engagement, but also stout engagement. Something like DT or King provide 18, 36, 54 or more points of simultaneous, radial engagement that distributes the load, thereby reducing the possibility of failure.

@simonstyles8537 Год назад

So just watched, to me I think they just didn’t have the audio recorded of the hub in both ‘oiled’ and ‘greased’ versions. Hence why we heard the oiled version, but not the greased. Editor simply didn’t have the audio to add it so added music to fill the void.

@zenscapeUKmedia Год назад

Ace video - well explained. The idea of noisy hubs is worrying. Noise is lost energy. And metal on metal = wear. It really doesn't matter if its soft steel or HS steel if both pawl and ring are the same - as hard steel will cut hard steel as soft steel will cut soft steel. Nice hubs, but the metallurgy will dictate they will wear faster. Its just science if the springs are too heavy. How come no one uses drawn clutch roller (Sprag) bearings specifically for one way drive? Lighter, cheaper and instant - and zero noise!

@kendorcruz9075 Год назад

If I’m not mistaken the Onyx Vesper hubs have a sprag clutch system and are almost if not completely silent.Haven’t ran them but I’m looking at a new wheel set and I’m considering a set of the onyx hubs

Built a custom set of wheels last winter with Christmas gifted I9 hydra hubs, couldn't be happier this season as it's my first local race series and the hubs have proved to help with the uphill. The noise coming down helps people know I'm behind them. I'm pretty sure helps keep wildlife away too. Thanks Doddy for the in depth look into I9 hubs.

@bryanwagnerseniormtb9940 Год назад

Doddy great video! As always your information is spot on. If I could add something about the cheaper hubs. You touched on technical up hill climbs and sometimes hearing the cracking sound from the hubs. What happened with mine was after experiencing that the hub can actually jam. It can also take small chips out of the teeth of the pawls. My suggestion to anyone that has just bought a bike and spent a couple thousand dollars is to be aware of the limitations of the cheaper hubs and adjust your riding accordingly. It is also difficult to get parts for cheap hubs. In my case the bike manufacturer didn’t even know what hub was on my bike because they source hubs from several different suppliers and the all have the same part number but can be slightly different. I’m now rolling on I9 enduro S wheels with hydra hubs and they are amazing. I found that the almost instant engagement is only noticeable in situations where you want to put the power down quickly there’s just no lag. Also when you have to ratchet your pedals that .52 degrees is a game changer. I don’t notice any pedal kick back when descending rough sections of trail on my bike.

@wiljaq2773 Год назад

Great vid! In 2020 I purchased a Evil The Following. In 2021 I saved up for a set of Industry Nine 315 carbon wheels with Hydra Hubs that completely transformed the bike. If you’re just hammering down mountains these hubs aren’t needed, but on technical rolling, rocky, rooty, trails like I ride HYDRAS ROCK!

@frankthetankricard Год назад

High points of engagement was never that appealing to me since I'm not a climber. Pedal kickback is more of a nuisance than engagement. The only tech I really want in hubs is silent ones. I was so bummed when Shimano axed their development of lower tier silent hubs. The current options on a market cost as much as a decent used mtb.

@toneloke7489 Год назад

It might have to do with your bikes suspension curve, but I totally get your point 👍

@frankthetankricard Год назад

@@toneloke7489 You are absolutely right, frame design contributes a lot. Still I feel like there's no drawback to a hub with sub 60 engagement points for downhill. I see people running complicated devices like the Ochain active spider to solve a problem that would rarely occur if they just ran a cheaper hub. For racers I get it, a lower number of engagement points is not a guarantee that you won't get pedal kickback 100 out of 100 times. But for the rest of us without sponsors I feel like it's a good compromise.

@lamefart Год назад

Yeah, that's the upside of lesser engagement hubs, less pedal kickback. I also find them smoother. I have 120T and 36T hubs. The times when your ride mates have to pedal while you're still freewheeling is such a treat. Lol There's another factor though, it depends how draggy your hubs are.

@cyclingoff-grid2837 Год назад

re going to be required to tune quite often, on these you gonna remove the tubeless tyres tapes volves to tune the rim

@hobmarg Год назад

I thought the impact of a freehub on pedal kickback is eliminated once you reach a certain speed (that is pretty slow, like 15km/h)? Assuming a reasonably tall gear as well. O-Chain is to deal with pedal kickback introduced by frame kinematics more than the drivetrain, at least from what I understand.

@gepetto____4669 Год назад

I have a regular Shimano hub on my 2022 (budget) hardtail, indeed it hampers every now and then when I put power through the cranks. At first I didn't know what it was but now I know it's the pick up from the hub, so thanks for the info!

@MrBenandbriar Год назад

I recently switched from a conventional hub to the i9. If the original hub hadn’t failed, I would not have given it a thought, but I LOVE the difference it’s made. No delay between pedaling and the wheel turning means better control up techy climbs, slightly faster acceleration out of corners, and (I think) better shifting. Lots of freehub oil keeps the sound to “fun” level, not overwhelming at all.

@tituslevico Год назад

In the Philippines, we have this term called "Tunog Mayaman" or "Sounding Rich" when the hubs sound extra loud and crisp.

@pintje87 Год назад

I'd love to see a comparison between a (3/6/...)pawl-system and a ratchet system, ideally also compared with an Onyx-hub (silent hub with infinite engagement). from a technical/practical point of view with advantages/disadvantages on the different systems.

@morskakumara1003 Год назад

I have onyx hubs which I admittedly haven’t ridden that much due to an injury. But for however much I have ridden them I couldn’t be happier. I just love the pure sound of rubber hitting the trail without the annoying buzzing. The sprag clutch works flawlessly and gives you pretty much as instant engagement as possible. Hubs are a bit heavier due to the sprag clutch system tho. However, since that weight is at the center of the wheel, you don’t really feel the difference, at least I couldn’t. If you like quiet trails and have money to spare I highly recommend.

@andrew.triggs Год назад

I really enjoyed Doddy's explanation of the hubs. I particularly enjoyed the talk about the flexing of the hubs. I had a set of Stan's wheels that always ate bearings, I guess that could be why.

@zebulundocallas Год назад

Between a pawl system and a ratchet system, I'll chose the ratchet one. Easier to service and I dont have to worry about losing engagement because it does not have pawl springs.

Hub is at the centre it's mass has a small effect on how quick or how much momentum your bike carries, these will only offer as you've stated quick engagement (assuming all hubs having similar lateral stiffness) For bike acceleration and deceleration having light rims etc.. matter as there is less force needed to input by the rider, but that does not equate to bike momentum as heavier rims once up to speed help produce your momentum it's just trying to slow them down 😄

@zenscapeUKmedia Год назад

I think you may need to look at the physics behind rotating mass and don't try to convince yourself otherwise. All race vehicles go for the lightest wheels they can along with the lowest un-sprung mass as even though it represents the lowest proportional actual weight of the total vehicle, it has the greatest effect on its performance.

@stevenconnor4221 Год назад

@@zenscapeUKmedia that wasn't the question. Work in = work out in any energy system. I'm just equating heavier wheels to a flywheel. And anyway it has no real world cause and effect on our mtbing world worth considering. What you any many others describe is acceleration and deceleration not the actual momentum or stored energy within the system.

@zenscapeUKmedia Год назад

@@stevenconnor4221 Again look at the physics. In a perfect system you theoretically have 100%, so work in =work out as you say. But you rarely get anywhere near 100% as there are so many factors taking their slice of the force. To change speed, first you have to overcome the mass of the object (bike) you're trying to move. Newton's 2nd law (F=MA) describes force required (from the rider) versus Mass (the weight of the wheel) and acceleration (rate of change). Any MTB session is not about straight, constant speed lines. Its all about acceleration (to counter a hill or obstacle), wind, braking and then restoring speed. About 25 years ago, I had my first pair of hand-built wheels made. It wasn't a great bike, but boy those wheels transformed it into something special. Doddy is 100% right about great, lighter wheels. Best investment you can ever make to any bike. But hey, stick with your heavy flywheels if you're happy riding at a constant speed over flat terrain. Each to his own.

I kind of tune out the sound, but it's there, for sure. I also use grease to quite it down. I have used the older Torch model and I found the drive side bearings wore out really quickly.

Dumb question, but when climbing technical sections, and there is rear wheel hesitation, how to you know if it's the cheap hub points of engagement, or just a momentary loss of tire traction in back? You can have all the points you want in the hub but if the tire cannot get enough traction for the lower gear ratio you are in, the tire's going to slip and the bike (and pedals) will hesitate. Therefore, tire selection for climbing would not be a tad more important...?

Get a wheelbuilder to build you a set, it can be cheaper than you think. Especially with alloy rims (go DT Swiss)

If you're in the UK you can't beat a Hope rim for price and durability

On The Other Hand... the placement of the ratchets on the inside of the hub shell, means the load bearings of the 'super hub' are Farther from the dropouts; in comparison to a basic shimano hub where the rachets are in the freehub body. that longer distance puts more bending stress on the axle. -they make up for it by going with a 12mm axle vs the 10mm of the basic shimano Still, this strikes me as a 'brute force' kind of solution vs cleverly spacing those bearings farther apart.

@Stussy787 Год назад

No mention of the Ringdrive system which is also relevant if you want to discuss hubs.

@glennmorgan8691 Год назад

When I was a kid in the 60's we used to grab my dads empty gigarette packs and mount them on the seat stay with a clothes pin so the pack went into the spokes now that my friends was a high engagement noise lmao

@AlexandarHullRichter Год назад

Nah, only 36 point. 😀

@tonyhruzek4250 Год назад

#askgmbntech - Great video! In your earlier videos I believe you states that the oil used to lubricate the hub would not sound as loud as the grease. Does it change with hub design??

@bartus9891 Год назад

How do lighter wheels carry more momentum? Momentum is mass * velocity, ergo less mass less momentum!

@janeblogs324 Год назад

Higher engagement does mean more pedal kickback though

@gsportgeorge Год назад

Doddy did mention that, however it's not as simple as that. It's a matter of probability. At the exact moment you compress the rear suspension super fast, the pawl can be anywhere on the drive ring with any hub. So if you have a super sloppy 15 degree engagement hub the pawl could still be right next to a tooth and engage instantly. It's just more likely with a faster engagement hub. But if you do the calculations for pedal kick back based on speed, you have to be going relatively slowly and compress the suspension super hard for the hub engagement to be a factor. The hub has to be spinning slower than the chain growth is happening and that's actually very rare.

@iradiateflu Год назад

I got a high engagement hub with +100 points on my dh and my enduro and I've never felt pedal kickback inconvenience me in any way

@Mathewvr 9 месяцев назад

My hub works normally but when I pedal in a low gear there's resistance and it ends up moving the cranks and it's made my chain fall off a few times and idk how to sort that is there anyone with advice?

@69basta Год назад

those spokes can twist on high tension, because of drag on the threads and the distance between the threads and the niples its gonna be a tiny twist and this is not ideal for a precise fine tuning

@n0ch91c3s Год назад

Standard steel spoke threads aren't cut, they're rolled. Material is not removed.

@vulcangamingvulcangamin3327 Год назад

can you help. convert qr 9x100 front hub to 15x110 thru axle

@MarkJolley Год назад

Why couldn't you replace the drive ring and pawls and convert a Torch to a Hydra?

@willlange9978 Год назад

This is “best on RU-vid” level video. Andrew, you’re on point.

@derekhobbs1102 Год назад

I'm still using 20yo LX, and prefer quiet freehubs.

@simonchaddock3694 Год назад

Could you check for microspline without taking the wheel apart cheers

@eugeniuszandrzejewski7505 Год назад

24 or 32 Spoke for wheel system?

@arose62 3 месяца назад

Momentum= mass x velocity. So, if you change to a lighter alternative, you will have LESS momentum. (About 2:00, where you claim lighter = "carry more momentum")

@orangielegros Год назад

You forgot to mention that the spoke don’t touch each other. Very unique

@bike.Xpw2020 Год назад

Which is faster, the closed axle 6200 or the normal axle

The I9 wheelsets puts a lot of questionmarks over my head: -afaik aluminum has no „infinite fatique“ properties, despite steel, carbon or titanium. The spokes are destined to break even in theory. - High engagement has little benefits in mtb despite road or trials. On full sus it has even theoretical drawbacks (pedal kickback) - the rotating mass almost solely matters on the outside of the diameter. Physically the heavier the center (hub/cassette/disc) of the wheel is compared to the outside (rim/tire) the faster it will accelerate. - good bearings are nice, still all the drag comes from the seals… It’s a lot of money for a peace of mind with no actual benefits 🫤 Hope Pro4 ftw. Even a loon like me can service them.

@a.r.8850 Год назад

good points, but i doubt that a 200g rim with a 300g hub will accelerate slower than the same rim with a 10kg hub.

are there cheaper no noise at all, i know the onyx vesper don;t make sound at all, but they are too expensive for me

@lux-3001 Год назад

2:04 how are lighter wheels carrying momentum better than heavier wheels?

@jimm244 6 месяцев назад

DT Swiss 370’s have been a disappointment to me. Pretty sure they’re 3 prawl with 18 points. They’ve held up super well, but 20° of slop kinda sucks for technical climbing. (New 370’s are star-ratchet so should be easy-ish to increase POE.). The fact that Santa Cruz laces Reserve Rims to these is kinda cheesy (not that I’m in a hurry to replace the set that I own). I’ve used a Stans S2 wheelset which I’ve liked quite a bit. 8° engagement. I think it’s an outstanding wheelset, especially for the money. I’ve ridden i9 1/1 (4°) a lot. The difference with S2’s is noticeable when paying attention, but I can’t say it really matters to me all that much on the trail. I’ve got a set of i9 E305 wheels inbound-with Hydra. Can’t wait to try them!

@tonyvanhout2394 Год назад

when is the beer vid coming out

@MrUnl0rd Год назад

So what happens to the spoke threads in those nice hubs when a stick gets in your wheel?

@countspokeula539 Год назад

You buy a new wheel 😉

@MrUnl0rd Год назад

@@countspokeula539 i guessed that 😆

@AlexandarHullRichter Год назад

Depends on the stick. My rear wheel has eaten so many sticks it must think they're tasty at this point. Doesn't even go out of true. I have DT wheels though, not these i9 things.

@soecyrexful Год назад

im all in maintenance free DT Swiss ratched system :D

@jamble7k Год назад

me too but not a fan of that new exp system

@TrIpMo1981 Год назад

ProfileRacing elite hubs, is the loudest and sounds the best.

@oldetymebiker2405 Год назад

Same here, technical climbing is the biggest advantage I notice. If I ride a bike without instant engagement, it's really noticeable now, like my mountain bike with curly bars.

@DanuelNuel Год назад

OK I fully understand - new advanced technology is cool and we need progress to have better bikes. BUT do we really need thousands engage points in hubs?
