Pinnacle of value and performance for aggressive riding
Carbon wheels are superior to alloy in every possible way: stiffer, greater impact resistance, longer lasting. But the price has been off putting, until now. The world’s strongest carbon rim is now available to you, hand-built for the most aggressive trails you’re willing to tackle, but with less impact on your wallet. With components proven in EWS and 2W races by Carl Jones and Raewyn Morrison, the Apex Stealth Carbon is laced with round-section double-butted DT Swiss spokes and our very own Dial36 hubs with 36-tooth engagement.
The Apex Stealth Carbon is a great match for your 150-160mm Enduro frame, or hard-hitting on a 140mm Trail / Enduro frame. Popular for its stiffness, which makes for an ultra stable wheelset in any trail condition, and backed by our lifetime warranty, including impact damage.
Like Henry Ford once said you can have any colour as long as it’s black.
This wheelset is designed to partner with a 150-160mm Enduro frame for aggressive riding and racing over the world’s toughest trails and terrain, and includes a comprehensive warranty for this type of use.
We design and build our carbon rims to last a very long time. Where is the fineprint? There isn’t any. As long as you’re using the wheelset for it’s intended use (no you can’t buy XC wheels and then race the National Downhill series on them like one customer did) we’re proud to offer a lifetime guarantee including impact damage.
We know from building hundreds of these wheelsets that the chance of something going wrong is extremely low but if it does we’re only a phonecall away.
The most common cause of broken spokes is poor wheelbuild quality. We go to painstaking lengths to accurately measure each and every rim and hub we build before calculating spoke lengths and cutting and rolling spokes to 0.1mm accuracy.
We have a lifetime guarantee against broken spokes and spoke nipples and we wouldn’t offer this we weren’t 100% confident in aluminium nipples and our ability to build a wheel using them.
Aluminium nipples save weight (just under a gram each) but get a bad reputation for three reasons – they seize to the spoke, they break, and they round-out where the spoke key turns them (generally because of reason #1)
We mitigate the risks of using aluminium and we don’t see problems with them. First we de-burr the inside of the spoke holes of aluminium rims: This means there are no burrs from drilling and it also helps to countersink the rim slightly to match the profile of the nipple. We then use a special grease on the spoke thread and the contact between the nipple and rim. This grease lasts a very long time and means the nipples won’t corrode to the stainless steel spoke.
Generally aluminium nipples break because of two reasons: the wheel wasn’t well-built, or the spoke was too short. Again, to mitigate these problems we measure the ERD (effective rim diameter) and flange geometry of every wheel I build, including combinations we’ve done previously as the ERD will vary by 1mm or so. We have custom software which calculates the spoke length very accurately, even going so far as to take into account how much the spokes will stretch due to their tension which is different on either side of the wheel because of the offset flanges. We then cut each spoke and roll it’s threads on a Japanese made machine. Our spoke lengths are accurate to around 0.1mm meaning the spoke sits flush with the top of the nipple ensuring all threads are engaged on the nipple and not placing the nipple under tensile loading.

All Stealth wheels use finely engineered Dial36 hubs; we don’t simply buy a hub and put our stickers on it and in every case we work with the manufacturer to incorporate our design goals. For example the Dial36 are made for us by a Taiwanese company who engineer hubs for large companies that every rider would be able to name. This company has the engineering skill and testing facilities to develop a freehub body system which is durable, creak-free, and easy to service….something very difficult to do. We then license this freehub body system and design the other features of the hub around it: Where the flanges are placed, the angle these flanges have, the spoke hole diameter, and the spoke hole chamfers. Our needs are often opposite to what the industry wants: for example we want a very small spoke hole diameter to support the spoke whereas the industry wants a very large hole to make lacing the spokes faster in a production environment (the reason why spokes break at the hub).
It rains a lot in New Zealand so we spec’d top of the line bearings hidden behind low-friction seals to ensure long running performance. Our wheelsets are sold around the world and when developing our hubs we took special care to ensure they would be easy to own and easy to service. No special tools are required to service the freehub body or swap between axle standards and hub bearings are normal sizes and easy to find.
If you have any questions about servicing or maintaining the Dial hub our trained and experienced staff are available to help.
Tubeless allows lower tyre pressure, more grip, and less punctures. It’s a no-brainer.
Tubeless rimtape is fitted and a pair of light weight CNC aluminium tubeless valves is supplied. Our attention to detail extends to the tubeless valves: serrated lockrings makes them easy to fit or remove and integrated wrench-flats are provided for super-tight valves. The valve cores are removable for easy cleaning or for assistance while installing difficult tubeless tyres. The inner section of the valve is optimised for our rims ensuring an easy air-tight fit.
Our commitment to you doesn’t end once we’ve got your money: If you have any questions maintaining or servicing your wheelset we’re here to help. Just get in touch.
Each wheel we build is engraved with a unique number and we keep detailed records dating back over 10 years tracking not just who built your wheels but minute details like spoke length, pre-stress procedure, and even what type of grease was used between the spoke and nipple.
