Okay so if I just hold this wheel up I'm sure the many of you will, be able to observe the fact is a maverick will, maverick. Of course is a name as synonymous, with cycling, its iconic, black and yellow branding, has been everywhere. Throughout the sport now. Though these days maverick actually make excellent cycling, shoes helmets, and even pedals, what, they really don't their fame for has been one of the longest standing wheel, manufacturers. In cycling. Now. Over the years maverick, is engineered, and pioneered, some amazing, technology on their, wheels and their rims including. SUV. Technology, ceramic. Coated, rims and of course the world-famous UST. Chiller, system now, SGP rims really, were a game changer as far as rim technology. Goes now. Traditionally, rims are pinned together and occasionally they'd be welded together and you'd, be left with a wheel there's perfectly good all the way around except, for the joint and you can have a bit of hop in a cab its side to side either. Way it didn't feel very good if you're braking with a rim brake back in a day or if you're a mechanic having, to lace those wheels up in the first place now. SGP technology. Changed, that completely by. Welding the rim together and then machining, that weld down leaving, a perfectly. Smooth and precise. Rim now. This was fantastic if, you had rim brakes this particular rim is a three to one so, this is one of the early downhill rooms designed for disc brakes there's also a 5 to 1 which was the rim brake version, which had a slightly deeper sidewall, and these, were SUV technology, rims now. I had an absolutely, perfect braking, surface and they were renowned, has been excellent, rims to lace up because they were so straight, to, start with now although this particular rim doesn't, have it they, had a one to one rim, which had a ceramic, coating on it now, a ceramic, coating in those days was amazing, for for two purposes in particular, on mountain, bikes now, the first one was the fact that it was quite a coarse coating, to actually adhere to brake pads really, really well and really basically.
It Gave you extreme. Braking, power well, as extreme as you could get with cantilevers, and v brace and those earlier days but. The other thing also did was give a surface, onto the outside of the rim it, would resist wear now, if you think a braking, on, a rim by today's standards has to be a mad you're, actually wearing out the structure, of the rim as you're breaking so, to actually enhance that, and basically make it a stronger rim in the first place this is what the ceramic-coated did, and it, was actually in fantastic, although it was quite expensive, now, of course there is the ust technology, as well UST. Stands for universal, standard, tubeless now, this was something that maverick, being a French company teamed, up with Hutchinson, and Michelin also. French companies but specializing, in rubber and they, teamed up together to make a universal, tubeless, standard, and this, is absolutely. Crucial at the time because there wasn't really anything like in it needed a wheel, manufacturer, to work in conjunction with a tire manufacturer, to do this so. Not only did, they design and pioneer, the valve core system, for inflating the rim I got, the rim bed system where's the sealed rim bed so there's no way of air getting through to where the spoke nipples penetrate, that and of, course the, hook technology, for getting that tire on there in the first place now, the reason for working directly with Hutchinson, and Michelin was, the fact that they could develop tires to, work specifically. With rims, like this and those tires obviously, had to be able to hold an air pressure in there regardless, of the sealant that was going into there to, create a completely. Toothless, system, now, UST, you've seen she was going everywhere but this is where it started and I think it's one of the most important, things that any suction company has done but, it's not just rims that navikev, been refining all these years they've, actually been making hubs since. 1975. Being. A hub manufacturer and a rim manufacturer, it wasn't gonna take him too long before they started wheeling out what they call the global system so complete. And optimized, wheel packages, that, first started in 1994. With the cosmic, range. Of wheels has two road wheels and then followed later in 1996. With, the cross mags series, of wheels of course this, is one of the later sets of cross max wheels today, though we're actually just gonna be looking at hubs because, it's such an important, part of the wheel so, let's go back to the very beginning, in fact in 1975. Where the Mavic 500. Hubs, came onto the scene now they might look pretty simple, to you but actually these house worked, a lot better than many hubs. Often, a decade, later, than, these now. In, this sort of era these, whole hubs tended, to be cup and cone design. Now. One of the problems with cup and cone bearings is it if you over tighten them you strain the bearing there you can pick the bearing surfaces, if you ride them loose it does the same and of course they, have additional friction if you ride them looser and the bearing surfaces get damaged or if you write them tight and, the same thing happens when I get pitted you get bumpy bearing surface now, another downside of the traditional, cup and cone bearing system is that they would loosen, slightly. As you wrote, now this depending, on how often you rode and the sort of surfaces, you rode on could be a ride or it could be several, rides now coupling kind bearings worked very, well provided. You. Like, to maintain your bike now it's not something that everyone likes to do and it's not something that everyone is good at doing and, mavet quickly identified. This so, actually, in these particular hubs, even, from 1975. They had sealed radial, bearings in them now something that's especially good, about maverick using, this sealed roller bearings are that, one of the weaknesses of, traditional.
Cup And cones or I put a slight, angular, force onto the bearings and she pre-loaded, them which, actually could prematurely, wear those bearings the, sealed radial bearings don't actually have that problem and they are immensely, smooth. Really. Really quite ahead of their time actually but, something else you're going to notice about this is how, different it is to a modern, mountain, bike hub so if I just take this one off a d-max wheel here look, at the difference not, just talking about the size but the layout the, help you see this one has a screw on style fitting here whereas this one has a much more familiar Shimano. Style pattern where, the cassette would slide on and screw on to the end there, now. The screw on system there wasn't any moving parts in the hub the hub simply. Had bearings. And seals and an axle no problem at all the, bearings however were separately, under the flanges there wasn't a bearing an outboard one at the end here so the hub could suffer, from strain there and also if there was flex that can create friction and, the bearing in a hub which of course will. Wear it out prematurely, caused. Additional friction none, of that stuff is any good now unlike the traditional cassettes, you see these days are literally slide onto the hub and held on the lock ring or in the SRAM case they push on and screw on these. Ones a little bit different they had a separate. Freehub body in fact just. Going to show you they have a. Separate. Freewheel, system, and these things weighed a ton compared, to what, you see nowadays because they've, got bearings, and pools inside. Here so. This would screw on to the hub itself, is, threaded, on the inside and it's threaded, there now. These. Things worked quite well. But. They weren't prone to problems I had quite a lot of friction in them due, to the amount of stuff there is going on in the inside of here you're very restricted. In how smaller. Smaller sprocket you can go for so, to compensate, for that the bikes using these tended, to have much bigger, chain rings up front to give you a big, gear range of course when it comes to mountain biking you want a smaller champion for the ground clearance, and you want a smaller small gear and a bigger big gear help back now. There's a quite limiting, and the way that could be designed and of course there, was flaws in the hub system as well because it wasn't supported, as well, it wasn't uncommon in these, days no matter what brand you're running to see these are hubs the axles bending and sometimes braking due to the additional strain the mountain biking would put to them I mean these particular ones are the road hubs but they did do a mountain, bike version, of them I just, want to show you the difference between the, fitting, on an old-style, screw, on what they called a block and a, new star cassette, where it slides on so as I've just explained, you have the simple scroll system that is all in one when it wears out you replace it and that, also has the poles inside. There now. With the system. You're far more familiar with you, have a cassette which is often in multiple. Pieces and it, simply slides. On or. Just find me the, biggest slots, here, there's. This one I. Simply. Slide on all, the pieces slide on and then they're held onto the end with. A lock. Ring it's, a nice simple system, the, mechanism, is actually on the inside here, this part of the hub can be removed there will be two, bearings in here and it'll be bearing supporting axle, so, the whole system gives much more support, it's, a much better system, especially. For, mountain biking but of course road, bikes also, use this system now, now the cassette hub there's, so much of it it's just so much better there's four, bearings in there in general so, much more support a lot more durability, that, better sealed, and much. Much, stronger, so, when it came to designing cassette. Star hubs like these mafic, were pretty radical. Even from that off and, I had a lot of 1000v in the hub's that other people hadn't, even considered using. Now, this particular hub you can look here you can see the dry side flange is a lot bigger than the non-drive side flange, and the reason, for that is it can accept shorter, spokes which means is stronger and stiffer now. They're also geared up for different lacing, pattern now, mavet used their own trade my cycle, spokes which was their own trademarked, alloy now, they were huge, flat spokes they're very light but also very, strong, one of the benefits of using a spokes especially, in the radial, pattern as, seen on this particular lab was they can get a spot line really, close to the cassette without fouling it of course the wider the, bracing angle is of course means, for a stronger and more tension tuile, on the, non-drive side they, tended to use to cross so if I just show you this on a prebuilt, wheel here so this is cross.
Max Enduro and as you can see here on the drive side it's, got that bigger flange with the radial. Spokes and then, on the non-drive side slightly. Different to cross spokes on here now as well as having fairly, radical spokes, options, that their own Brad spokes there and of, course doing to cross and radial, patterns, it, was the number of spokes that free to people out to now, this particular wheel is a rear wheel and it, has only 20, spokes, on it and you think a normal, spoke, to mount apart we were back in those days would have had 32, or even 36, spokes. Which could be stainless steel as well these were all away so really, really advanced. Stuff there, now, there's, a whole bunch of other things that they had where other hub manufacturers, were offering quick-release or bolt through or twenty mill or this call that Mavic. Were very quick to have adaptive. Systems, that you could change to seat 135, to 140 s and everything. Else so it's a really adaptable, system. Which of course is. Much, better for the end user now, also having, used to have sealed, bearings, in all of their hubs, so you, had no issues, with that sort of stuff in there and they never suffered, because, their radial bearings from having any angular, load to them that you could get in someone's, cup and cone systems, now. In the, early days their hubs you would adjust the, preload on them but they learnt that whilst that worked excellently. It. Could be over adjusted. You could tighten, too much likewise. There could be ridden when they were loose so. The later hubs came, with what's called the cure S auto preload. System, now this sister is fantastic, because it means that bearing is that the optimum. Preload at all time so you're not going to wear the bearing through anything other than just old age really it's a really really good system now, as far as the internals. Of the hub's go Mavic, have always had their i TS system, which is instant, transfer, system, now. In the past they've had to pull systems, but, i want to show you that i TS four which is the most recent, incarnation of that and that's as featured. Inside this particular hub, here now. It's a very simple. And effective system. We have four, pulls on Springs, here now they're staggered so. It means that there's always two, engaged, at every time it's not a case of none. Engaged and then all engaged as they spring around and simply. Put these just engage into a ratchet, this on the inside, of the hub that is simply a seal there to keep, all the grime now it's, a very simple, and effective system however, this system is excellent, as it is does, need maintenance on it because. Of the fact that the poles are on Springs, over time those, springs do need replacing because they can get a bit baggy and not actually, do their job as well as I should do with pushing the spring into, the ratchet, there and of, course if you were to put a thick grease or something in there they could slip but. Generally, it's a really really good system and this is the most refined, version, of that with those staggered, pulls so, I'm just going to pull this hub apart, here so you can see the, insider I loosened this earlier it's not normally this is just. So you can see take the end cap off and. Then. Just with a gentle pull, you, can see it's the same as this one and then. If I just. Release. It. Yeah, for me you, can see it's the same again, and, you can see on the inside here, where. Those pull sit into that ratchet and. Allow. It to freewheel, or engage, that hub it's. A pretty good system is, always worked, really effectively, but that with, the two always, engaged is far more reliable than earlier systems the, key for any sort of intricate, machinery like this is, the fact that has to be cleaned and well, lubricated, in, order to work reliably, all the time of, course we're not all like that and that's Mavic new from the hub days when, they started using cartridge, bearings instead, of using cup. And cone bearings people, don't want to be maintaining, their bikes all the time so. This, CUDA CICS force system is and, it still does work very well, Mavic, we're interested, in developing a new system that didn't have to rely on people looking after it as much now, as we know mavica. Masters, refining. Their products throughout the entire range and this, is the latest version, of their hub so, on the inside of this hub a little bit different from the old star i TS 4 system is the brand new ID 360. I D, stands, for instant, drive and this is all new, now, Mavic have actually, been developing, the ID 360. System since, 2013. And. It's, been used on our skinny wheeled road bike friends bikes since. 2016. And now has finally, been, adapted. And ready for mountain, bike use unlike. The DT system which has the two batches and twin, Springs, maverick. System it just has a single spring, so, let's have a look at it okay so this is the freehub body listen.
To This. Almost. Instant. Engagement is 40 points, of engagement, on this there's, just nine degrees between. Them that's, such. A fast pickup, now. I'm just going to release the spring this so you can see how, this works on the inside here and it. Take this apart so, you have the partner sits into, the hub with one set of the ratchet rings on it you, know the other ratchet ring that, rotates. Against, it you. Have the spring this is on inside the for your body it's. That simple, and it's, going to show you this on the inside a hub just like I did with the other one it's, going to pull this and plug off and, literally pull. This apart. Here, we go there's the spring here's, the ratchet and there's the other one on the inside of the hub they're very, simple, system, as, you can see the ratchet is pushed away from the hub allowing it to freewheel, and when. You go the other way it engages now I've also got this really cool, cutaway, hub here so you can see the axle you can see the bearings, if, you look closely you can see these ratchets, and as I rotate this you'll, see it engaging with that single spring, just. Making it coming to use there very, cool okay. So let's look at the fundamentals, of this ID 360. System so. Of course there's 40, points, of engagement, it's positive, engagement it's basically always ready, to be engaged no chance of slippage, there it's. 9 degrees of, rotation. Between the, engagement which is tiny, however. It's not too small so the bearings, on the inside, obviously they're premium, bearings, and I don't have any angular, sort of load concerns. To them and also know how outboard, those bearings, are of course because the ratchet mechanism the, inner, one is slightly on the inside here the outboard, one here is very very, close to the outside here and again, on the initial free hub part of the body there you, might also notice that system, has an oversized, hub now most people tend, to have a 15, millimeter, axle, in their hubs but, Mavic with the ID 360. System have a 17, millimeter axle. Now. 2, millimeters, might not sound a lot to you but it makes a significant. Difference and. We've got a thing is with all of those twisting, forces that go into bikes especially to. Date with the way they've ridden I'm talking enduro bikes trail bikes jump bikes downhill, bikes all of that stuff when, you're throwing those bikes into turns everything, is twisting, and as soon as they're twisting, Affleck's in something like a wheel axle, that's, going to create a load on bearings, and other parts, that is not good now. This system has been designed to cope with all of the stresses of modern day bikes and to. The particular things that, are included in that or ebikes. Of course they put a significant, amount of strain and talk through, a rear axle like this this actual laughs had it no problem with that also another thing to bring up is the enormous, 51. Tooth teeth. The sprockets, you get on some, really cassettes these days are they / significance. Or load into. A hub and again, with this system combined. With, that ratchet it's. No problem at all you're never going to slip and that, axle, can handle the strain now, what I can feel here that you're gonna have to just listen to is a really, really nice crispness. Now. There's actually 50%, more torsional, rigidity in, this system than, a conventional ITES, for pull based system so you've only got to think how efficient, that's going to be under power now, also there's the noise thing to take into consideration, obviously with, it outside of the hub. That. Is extremely. Loud, and extremely, positive, you, know that that is in. But. With the cutaway, system, here. It's. Far more muted, and then with the actual hub itself, where. It's completely sealed in it's. Actually quite discreet. It's definitely crisp, enough to know you're, in the whole time, but it's not too distracting on the ride I actually, really, like the fact is not super, loud I've, been quite liking, the quiet bike thing of late, and start to see it more and more of course clutch to raelians and stuff it's all about making your bike as quiet as possible, and. That's when I think it's going to start reducing noise, but obviously there's no chance of slipping, or anything it's. A really really good positive system, there's, also a severe, lack of.
Friction In this normally. The only friction you would feel on this whole star system would, be the, actual ratchet, itself and in the seal but the seal is a non-contact, seal. So you don't feel that any way and the only thing you feel is literally, the ratchet against yourself which I can tell you is very reassuring, now, that about summarizes. The hub also about, 40, grams lightest, and not only does, it outperform. Their. Old and a more conventional RTS, 4 system but it is a slight bit lighter now, something else I just found out about these obviously, Maverick is a French company they hail from annecy in, the French Alps there and actually, make their, hubs in Europe, which is quite nice now, it still looks like a modern wheel to me and I know how well these ride because this is actually one of my personal. Wheels from another bike but. I find it quite amazing, that Mavic in particular the, way they'd like to refine, their products, through time like this is still great up to they still works but, the latest one if I just show you that X a 35, carbon. The pro will this, is the latest one and this of course has, got that ID 360. Hub on, there it's. Got to cross designed, on both. Sides 24, spokes it's got the carbon, rims on here which is set for anything from 2.5. Up to 3.2, inch tires, nice, stable, support this UST, as you'd expect, as, with the newer wheels, from mavica spotted WTS, systems there's a wheel tire systems, that a whole lot with tires involved. In the formula there too I think. It's really impressive that the fact that they. Don't just sit on the fact that this stuff is excellent, worse they're always looking to refine, and make, stuff better the longevity of, stuff, now. Something I haven't mentioned yet but I really. Really like about this, new ID 360. System is, that this is going to appear on automatic. Wheel soon so. It's already out there in the wild on some of their wheels but I think the point I want to make is that on some manufactures. Wheels you will see the pool system be continued to use on maybe slightly, more budget, wheels and they'll use a ratchet system on a slightly more expensive wheels. Whereas, I love, the fact that Mavic they, totally believe in where they're going with the ratchet system and that it's going to be on all wheels so, whether you're riding, a 200 dollar set wheels were $2,000, set of wheels you're going to get the same performance the, same longevity, and the same technology, in there so, you go that was a little story about maverick the French wheel manufacture, I hope you, liked the little story there as always, click on the round globe to subscribe, to Jam bein tech we love having you guys around and if.
