Engineered with a rim that’s precisely machined for lighter weight and uncompromising strength, the Crossmax Pro elevates the XC experience—whether you’re racing, training or just shredding trails. With an internal width of 22mm and our patented ISM 4D technology, the rim provides a lightweight and dynamic ride quality. The ISM 4D process machines the rim between each spoke hole. This reduces weight without compromising strength, making it easier to climb and accelerate. The Zicral spokes and Isopulse (rear) lacing increase wheel stiffness for sharp, predictable handling. This is a fully tubeless UST system without the use of tape, making it easy to experience the benefits of tubeless, including better traction and fewer punctures. The system is compatible with quick release and 15mm thru-axle on the front, quick release and 12mm thru-axle in the rear. You can choose standard (15x100 and 12x142) or Boost versions in either 27.5" and 29".

MTB Wheel Sizing

When buying a new set of wheels, it is essential that you choose ones that are compatible with your mountain bike. This means that you will need wheels that have the same diameter rim, the same hub width and the same axle diameter as the existing wheels on your bike.

Rim sizes

Rim Diameter

There are four mountain bike rim diameters that relate to the four main wheel sizes.

If you are upgrading your wheels, then in most cases you will have to use wheels with the same diameter as the originals. The exception to this is bikes that are specifically designed to work with both 29” and 27.5” plus sized wheels.

29”	The largest MTB wheel size, found on 29ers
27.5”	Also known as 650b, this is the most common MTB wheel size 27.5” + (plus) wheels have the same diameter as regular 27.5” wheels but have wider rims.
26”	The traditional MTB wheel size, now only found on dirt jump bikes, some small size adult bikes and junior bikes.
24”	Found on some dirt jump bikes and Junior MTBs.

Rim Width

Rim width can be measured from the inside or the outside of the rim, but it is the internal rim width measurement that matters most. Wider rims are best suited to wider tyres. Bikes with Boost hub spacing have more room for wide tyres. While all rim widths for a specific rim size will fit your bike wider tyres may not.

Hub Sizes

Axle Diameter

Traditional Quick Release (QR) axles have a 9mm (front) or 10mm (rear) axle diameter. These work with conventional dropouts similar to those found on road bikes. Many mountain bikes now use thru axles (TA) for improved handling.

Front Axle Diameter – 15mm thru axles, are the most common on trail, enduro and cross-country MTBs. 20mm thru axles are mostly found on downhill bikes. Many forks have some type of quick release thru axle so may be referred to as 15QR or 20QR. Traditional 9mm QR axles are found on affordable hardtails and MTBs with rigid forks.

Rear Axle Diameter – 12mm is the most common thru axle size. 10mm QR axles are found on more affordable full sus and hardtail MTBs. 10mm thru axles and 10mm bolt on axles are found on some older bikes, these are compatible with conventional dropouts.

Hub Width

Front Hubs – There are two front MTB front hub widths. The traditional width is 100mm. Many high-end mountain bikes now use the wider Boost axle standard which is 110mm. Downhill hubs with 20mm axles have traditionally used the 110mm hub spacing. New Boost downhill hubs use the same hub width and axle diameter but the hub flanges are wider so the brake rotor sits in a different position.

Rear Hubs – Rear axles are a little more complicated. The traditional MTB rear axle width is 135mm but 142mm is more common with thru axles. The Boost standard for rear hubs is wider at 148mm. Downhill bikes tend to have even wider hubs. 150mm is a common DH hub width but there is also the new 157mm Super Boost standard that is found on some Downhill bikes.

Front Wheel

Hub Width	Axle diameter	Type	Common Use
100mm	9mm	Quick Release	Traditional, found on entry level hardtail MTBs
100mm	15mm	15mm thru axle	For older trail MTBs
110mm	15mm	15mm Boost thru axle	For Boost compatible single-crown forks
110mm	20mm	20mm thru axle	For downhill forks
110mm	20mm	20mm Boost thru axle	For Boost compatible downhill forks

Rear Wheel

Hub Width	Axle diameter	Type	Common Use
135mm	10mm	Quick Release or Bolt On	Entry level MTBs and Dirt Jump bikes
142mm	12mm	12mm thru axle	Traditional MTBs with thru axles
148mm	12mm	12mm Boost thru axle	Boost compatible XC, trail and enduro MTBs
150mm	12mm	12mm thru axle	Downhill bikes
157mm	12mm	12mm Super Boost thru axle	Super Boost compatible downhill bikes

Note: some wheels are supplied with adaptors that makes them compatible with both quick release and thru axles.

Brake Compatibility

Choosing wheels that are compatible with the brakes on your bike is essential.

Rim Brakes

If you have rim brakes on your bike than you will need a non-disc wheel that has a braking surface on the rim. Non-disc wheels are not compatible with disc brakes.

Disc Brakes

You will need disc compatible wheels for a mountain bike with disc brakes. There are two ways of mounting discs to your wheel. If you want to use your existing disc rotors, then look for a wheel that has the same mounting system.

6 Bolt rotors – The disc rotor is attached to the hub with six bolts. This is the traditional way of attaching a rotor to your wheel and is still the most common.

CenterLock – Developed by Shimano this system is easy to use but centre lock hubs are less common than six bolt.

Adaptors are available, so you can convert a 6 bolt wheel to CenterLock and visa versa.

Freehub Compatibility

The freehub is the part of the rear hub that the cassette is attached to. There are four main types of freehub for mountain bike wheels, each is designed for a specific type of rear cassette.

Shimano Hyperglide splined

This is the most common type of freehub body. Most 7, 8, 9 and 10 speed cassettes, as well as some 11 & 12 speed cassettes are designed to work with the Shimano Hyperglide splined freehub body. This includes SRAM 7, 8, 9 and 10 speed, as well as SRAM NX 11 & 12 speed cassettes.

SRAM XD

Most SRAM 11 and 12 speed cassettes are designed to work with a SRAM XD freehub driver.

Hope Freehub

Hope’s unique freehub body is designed to work exclusively with Hope cassettes.

Shimano Micro-Spline

Shimano’s new freehub body is designed to work with Shimano 12 speed systems.

Brand compatibility

While most rims and hubs are laced together in a standard way some brands do things a little differently. Cannondale use their Ai (Asymmetric Integration) system on many of their new full-sus MTBs. This means that the rim sits in a different position to a standard wheel, so you will have to either upgrade to a compatible Ai wheel or get a standard wheel adjusted by a professional wheel builder.

Jargon Buster

Bolt On – an axle that is incorporated into the hub with nuts on the end. Designed to work with traditional 9mm or 10mm dropouts.

Bolt Though Axle – an axle that goes through the hub body and fixes to the fork or frame of you bike.

Butted – where excess material has been removed from low stress areas.

Eyelet - A fitting in the rim that holds the nipple in place.

Freehub – The freehub allows the rider to stop pedalling whilst the bike is still moving forward. The rear cassette is attached to the freehub body.

Hub - The centrepiece of the wheel, from which the spokes branch out to the rim. Rotates around the axle, which is an external component attached to the fork or frame.

Hub flange - The collar of the hub that the spokes attach to.

Lacing - The pattern in which the spokes are threaded when building a wheel. The exact same wheel threaded in a different pattern can produce a completely different ride character.

Nipple – The small component that the spokes screw into at the rim.

Rim - The outermost component in a wheel. The bit the tyre sits on.

Spoke - The rods connecting hub to rim. J-Bend spokes are most common – they are identified by the bend at the hub end, and thread into the nipple at the rim. Straight-pull spokes have no bend and, as they are often proprietary to the wheel they are made for, are less readily available in bike shops.

Tubeless – Technology that allows does away with the inner tube

Tubeless rim tape – Rim tape that makes an air tight seal around the rim of tubeless compatible wheels

Tubeless Sealant – latex based liquid that you put inside tubeless tyres to get a good airtight seal. Tubeless sealant will self-repair small punctures.

True - A straight wheel is called ‘true’. If it gets a wobble, usually caused by the spokes unequally going out of tension, it is out of true.

Valves – The port of the bike that is used to inflate and deflate the tyre. There are two types of valve for bikes. Schrader valves are the same as those on car tyres while Presta valves are narrower bike specific valves designed for high air pressures. Valves are attached to the rim in tubeless set ups or included with the inner tube on traditional wheel setups.

QR – Quick release. Designed to work with traditional 9mm or 10mm dropouts. A quick release skewer fits through the wheel and allows you to quickly change the wheel.

TA – Through axle. See Bolt Through Axle above.

Wheelset – both the front and the rear wheels are included in the wheelset
