Bearing type: Good-quality bearings, sealed and protected from dirt and water, are the key to long and healthy hubs. Older or less expensive hubs may use cup and cone bearings, which contains two rings of loose ball bearings that sit in 'cups 'inside the hub body, and are secured in place by conical nuts known as' cones'. The balls can rotate freely between the cup and cone with each unit making up one bearing.
Cup and cone bearings have the advantage of being easily serviced at home – new bearings and a dollop of grease once in a while are all you need to keep them running smoothly – but they can be tricky to adjust perfectly. More expensive hubs may use cartridge bearings , where the steel balls or needles rotate in a single cartridge unit that can be easily removed for servicing or replaced once worn out. Many riders prefer the convenience of cartridge bearings – no more tedious micro-adjusting or hunting for stray ball bearings mid- service – but they are more expensive to replace.
• Materials: Most MTB hubs, front and rear, will be made of lightweight aluminium alloy although carbon fibre units are available at the top end of the market. Rear hubs for trail, jump and gravity bikes may use steel rather than aluminium freewheels to prevent the softer alloy splines being chewed up by the cassette under heavy load.
• Brake rotor compatibility: Bikes running disc brake systems need hubs to which the disc rotor can attach. There are two main standards for rotor mounting, six-bolt and Centrelock . As the name suggests, six-bolt systems have hubs with six evenly- spaced holes to bolt on a matching rotor. Rotor bolts generally use Torx heads so you will need to make sure you have a Torx tool to tighten or loosen them – don't try to fudge the job with an Allen key or you will risk stripping the bolts.
The Centrelock system used by Shimano foregoes rotor bolts in favour of a splined hub-rotor interface secured with a locking ring (special tool needed). This is claimed to reduce installation time but it does put limits on mixing and matching hubs and brakes as most other manufacturers stick with the six-bolt system. Again however, adaptors are available to mount six-bolt rotors to Centrelock hubs, and vice-versa. Before investing in new hubs check which disc interface you are currently using and buy accordingly.
• Axle size (front): You must also ensure that your hubs are compatible with your fork axle. Many entry-level or shorter-travel cross-country forks attach to the hubs via quick-release (QR) skewers, with a 9mm diameter axle clamped into the fork and frame dropouts via a 5mm QR skewer. However recent years have seen the growth of the 'bolt-through' or 'thru-axle' standard on MTB front forks for trail, enduro and gravity riders. This uses a larger-diameter (12mm, 15mm or 20mm) axle for extra stiffness and security, with the axle threading right through the fork ends and being secured by two QR clamps integrated into the fork lowers.
If you intend to upgrade your wheels make sure the hubs match whichever axle standard you are using, or alternate consider hubs that can switch between QR and bolt-through with the insertion of a simple adaptor to enable the wheels to be used with different fork types .

Why stand over a pan of solvent and breathe fumes while you scrub? Let our machines do the work for you - and get every nook and cranny scrubbed clean.
These ultrasonic systems are designed for the serious professional who needs to degrease metal parts quickly and effectively. We offer two configurations, and will be happy to put together a specially sized system with accessories to suit your needs. Ultrasonic cleaning is perfect for carburators, engine and other intricate metal parts, because it can reach into the tiniest openings and blind
Ultrasonic cleaning is primarily an aqueous tank system that uses ultrasonic energy to remove dirt, grease, oil, And baked-on carbon from parts. Contaminants such as paint, rust, glued-on gaskets, and heavy layers of bakedonCarbon can also be removed by ultrasonic cleaning but require more aggressive chemistries. Unlike someOther cleaning processes, ultrasonic cleaning will not damage intricate, lightweight, or easily damaged parts. Parts that have a tendency to tightly nest will shadow each other, reducing cleaning efficiency.
How it Works
Ultrasonic cleaning works by producing sound waves in liquids. The waves consist of both high- and low-pressureFronts. The low-pressure fronts are small enough to cause bubbles to form. The high-pressure fronts cause the bubblesTo collapse. The expanding and collapsing bubbles loosen contaminants on the part surface and the chemical cleanersEither dissolve or segregate the free contaminants.
As with sound waves in air, ultrasonic sound waves can be varied by both frequency (pitch) and amplitude (power). Higher frequencies will produce smaller bubbles and lower frequencies will produce larger bubbles. Larger bubblesWill typically dislodge large particles and smaller bubbles small particles. Typical industrial systems are either 28kHz or 40 kHz, which can handle the particle sizes in the range of normal automotive cleaning. Ultrasonic cleaningSystems with a much higher frequency are used in the computer industry where tiny particles need to be removed.
Configuration of Equipment
The most basic piece of equipment for ultrasonic cleaning is a stainless steel tank with an ultrasonicTransducer and power supply (frequency generator), and is usually referred to as a benchtop unit. MoreAdvanced units may include features such as heating, filtration, mechanical agitation, rotating baskets, Ultrasonic power controls, oil skimmers, water level controls, and frequency modulators to improveSolution degassing.
No More Solvents!
A carburetor remanufacturer formerly used manual solvents parts washers to clean Carburetors. This was a very labor-intensive operation, requiring a technician to spend between 15-20 minutes per carburetor. In many cases, the carburetor then required additional cleaning in a DIP tank containing caustic soda, followed by a hot water rinse.

• Axle size (rear): Rear hubs are sized according to the diameter and length of the rear axle (measured in millimetres). The standard MTB rear axle dimensions are 135x5mm (for a QR rear hub) but jump and gravity bikes may use wider and thick axles for extra strength and stiffness, with the available sizes being 135 × 10, 142 × 12, 150 × 12, 157 × 12 and 165 × 12. Ensure your rear hub is the correct size to fit your frame.
• Rims: If choosing a new hub to rebuild a wheelset you will need to match the number and type of spoke holes on the hub's flange to the number and type of spoke holds drilled into the rim, eg a 32h hub is designed for a 32 -spoke wheel, and needs to be matched to a 32h rim.
