This measurement depends on the frame design, so be sure to find out what size rear hub your bike requires. The available mountain bike sizes are: x12, x12, x12, x12,x10 and x5mm. Rear hub bodies and freewheel bodies are made from aluminum because it is both light and stiff.
Some hubs use a carbon fiber middle section to save weight. Axles come in steel, aluminum or titanium. Bearings are available in steel or ceramic options.
Before shopping around for a hub, be sure to know what size of axle your frame requires, and whether or not you require an internally geared model.
Once that is sorted out, there are a few criteria that may help choosing the best model for you: intended use, bearing type and rotor compatibility.
A hub's general design depends on the type of riding it was intended for. Downhill and freeride hubs are built to withstand the abusive nature of their disciplines. Cross-country hubs shed some unnecessary material and weight because of the more docile application. All-mountain rear hubs fall somewhere in between, balancing strength and lightness in their designs. Hubs also use different qualities and types of bearings.
Some manufacturers choose loose pack bearings, while others prefer sealed designs. At the back, the micro-ratcheting freehub sees degrees of engagement and both ends feature centre lock rotor mounts.
The Saint hubs get a one-piece axle which not only shaves weight but also increases strength. The front hub takes a 20xmm thru-axle to ensure no steering input is lost to deflection and the rear hub comes in a mm super-boost spacing.
As a general rule of thumb, the louder the hub, the higher the quality. The idea of putting playing cards in your spokes stopped being cool on your 11th birthday, so why do hubs that make the same amount of noise corner the top end of the market? With this in mind, Onyx's Racing hubs offer instant engagement with silent freewheeling.
The brand achieves this using a sprag clutch instead of a traditional pawl spring and ratchet setup. A sprag clutch looks a bit like a cartridge bearing but with figure-eight shaped sprags which, when turned backwards, tilt and lock into place. The Racing hubs have two rows of sprags which make for lightning fast engagement with zero noise. The only downside is they are a bit porky at g. With points or 1. Using magnetic pawls, they are lightning quick and come in loud and quiet versions so the hub can be tuned to your preference.
The hubs spin around Japanese EZO bearings which are buttery smooth, and the Project hubs feature a bearing preload screw to maximise their lifespan. The hubs also utilise interchangeable end caps available for every modern axle's standard and width. White Industries has been making bike parts since and since then their hubs have become some of the most sought after on the market.
The XMR hubs are available in boost and non-boost configurations and utilise end caps to compensate for axle diameter variations - sorry no 20mm here. The driver body uses a three-pawl system and comes stock with 24 points of engagement, though White Industries will upgrade you to 48 for no extra charge — it begs the question why the 24 option is even available.
Servicing the hub only requires a 2mm hex wrench meaning the friction-free, ride quality, WI hubs are easy to maintain. They also come with a bearing preload adjustment to prolong the life of the included ABEC 5 bearings. Born and bred in Colorado, and now based in Australia, Colin comes from a ski racing background and started riding as a way to stay fit through the summer months.
His father, a former European pro, convinced him to join the Colorado State University collegiate cycling team, and he hasn't stopped since. It's not often he pins on a number nowadays, and you'll likely find him in search of flowy singletrack, gravel roads and hairpin corners. Colin has worked at BikeRadar.
Bike Perfect. Included in this guide: 1. Simply put, these bicycles have revolutionized mountain biking. They can be correctly described as the apex of cycling technology, as their ability to deal with tricky terrains like mountains and hillsides is something worth marveling at.
Among their many parts, one of the most intriguing is the hubs found on their wheels. What are they exactly? A bike hub is the central part of bicycle wheels made up of the axle, the bearings, and the hub shell. The Hope Pro 4 EVO came as a successor to the Pro 2 that has received a lot of love from bike enthusiasts worldwide; it still shares a lot with that version.
As much as its predecessor was good, the Pro 4 has gone further steps forward by adding improvements to an already amazing mountain bike hub. The Pro 4 rear hub weighs g and is crafted out of aluminum billet with stainless steel cartridge bearings. The Shimano Deore XT front mountain bicycle hub is one of those parts. The bearings are in angular contact with the wheel, creating an efficient type of friction that makes the ride more comfortable by significantly reducing the damage change to the hub.
This is the kind of rear hub you go for when comfort is your priority. The closest competition Shimano has had for years as far as quality is concerned has come from DT Swiss. The hub engagement system has 36 points that allow the rider to get the most out of their mountain bike. With an impressive grammage of and a large diameter, the DT Swiss hub has the strength needed to keep the bike running at optimum levels for years before you start entertaining the idea of a replacement.
The Onyx MTB rear hub is another beautiful piece of machinery that pays close attention to performance than anything else. The hub has bearings created out of hybrid ceramic that makes them lighter and stronger than others from major brands. The whole system has unique sprag-clutch mechanization that triggers instant hub engagement when power is applied. Chris King makes proprietary rear hubs that boast of unmatched mechanical tolerance. Having identified how important rear hubs are for wheel strength and performance, the company focused on creating the right products to bring that into reality, and they successfully pulled it off.
Maintenance of the Chris King hub has been made easier by the provision of a 2. The Chris King ISO has 72 points of simultaneous engagements that make switching up gears super fast and efficient. Out of Stock. The idea of working on your bike can be a little daunting for new riders but a bit of regular maintenance performed before each ride will make your bike time more enjoyable and keep your steed perform New to mountain biking?
