Frequently Asked Questions

If you saw -- and lifted and flexed and rode and won on -- ADA wheels, you would understand.
Why should I consider custom-built wheels?
Custom wheels is an idea whose time has come. All pro riders, many elite amateurs and uncompromising fitness cyclists fully realize the benefits of a custom-built frame. But, many of these same cyclists settle for wheels built with standard off-the-shelf components, despite the evidence that a perfectly balanced, lightweight set of wheels is the single piece of equipment that can have the most stunning impact on your cycling performance.

So, whether you're a natural climber who dances up the steepest mountains with finesse, a powerful sprinter who surges ahead through brute force, or a balanced all-arounder who excels in all disciplines, you can benefit from a custom-built wheelset. If you can visualize the experience of riding a set of wheels whose design is based on your specific body weight and riding style, then you should consider ADAs. If you can imagine the quiet confidence that comes from riding a set of wheels that have the perfect combination of lightness and durability, then you should consider ADAs. And if you know that deep inside you'll never be truly satisfied until you've ridden the best, then you should consider investing in a set of custom-built ADA wheels.
Which pros use ADA wheels? Will ADA wheels make me faster? How durable are ADA wheels? What if a spoke breaks or the wheel needs to be trued?
ADA wheels are exceptionally durable. If your wheels are used in the conditions for which they were built, it is highly unlikely that they will ever need any repair work. Their exceptional durability has been proven time and time again in the most severe professional racing environment.

We must all recognize, however, that ADA wheels are built for speed, and that accidents do occur in racing situations. If your wheel breaks in a crash and it is unrepairable, we will build a new wheel for you at half of the original price. In the unlikely event that a spoke breaks or the wheel goes out of true, it must be returned to us for repair.

Do the durability and stiffness of ADA wheels result in a harsh ride?
This question is based a common misunderstanding of the role of wheels in contributing to ride quality. To dampen road shock, a wheel would have to flex in the vertical plane, and no wheel does this. Choice of tire and tire pressure will have a far greater impact on the perceived "harshness" or "comfort" of your wheels.

However, ADA wheels' lateral stiffness compared to traditional wheels is of real benefit to you. This lack of flex results in an extremely stable and precise-handling wheel that will bring you a new level of psychological "comfort" on high-speed, technical descents.

What are the aerodynamic properties of ADA wheels?
In tests with elite cyclists, ADA wheels were found to provide significant advantages in both aerodynamics and inertia.  Granted, disk-type wheels still provide, under ideal conditions, the best aerodynamics.  Compared to ADA wheels, disk wheels provide at best 5 watts more power at 50 kph; but, this small increase in power comes at the cost of high rotational inertia (heavy mass) and control problems.

ADA wheels are designed to achieve an ideal balance between low weight (100s of grams less than so-called ultra light climbing wheels), high strength, excellent aerodynamics, and complete control in all kinds of riding conditions.

Why don't you publish comparative data with other wheels?
We don't publish comparative data because there is no standard way of testing; therefore, reported results of aerodynamic testing should be taken with a grain of salt.  Instead of making a one-dimensional wheel whose impressive wind-tunnel data might look great on paper, we at ADA concentrate on making balanced wheels whose performance is impressive on the road, in real-world conditions.

For years we have been collecting performance data on our wheels in racing conditions by means of SRM cranks.  However, we don't collect these data simply to "market" our wheels; instead, we have used this data to improve the design of our wheels.

Can I service the hubs myself?  Can I use my current drive train? Can I specify tubular or clincher rims? What other options are available? What are the differences between kevlar and carbon braking surfaces? Do I need special brake pads? Can I mount a cyclo-computer magnet on the wheel? How long will it take before I receive my wheels?

How can I get more information about ADA wheels?
