Wheel diameter: Commonly, road wheels are 700x26. 700 is the diameter of the wheel (actual diameter is 622mm to the bead seating, but most just say 700). 26 is the width of the wheel (see image above). The depth of the carbon fiber rim is measured from where the tire meets the rim all the way to the nipple attachment (see image above). In this example, the The Atom Composites CR 38 rim extends an additional 38 millimeters toward the hub. We offer rim depth size ranges of 28mm, 38mm, 50mm, 60mm, 85mm. The best use cases for each are described in more detail below. All of our wheels can accommodate running tubeless and we offer a complete tire set up if desired.
Atom’s 28mm wheelset is best for the “climber”. They are Atom's lightest wheels and offer perfect aerodynamics to enhance every bike’s ride. The depth provides low drag and minimal crosswind effects to ensure a stable rotation at any speed, making a great all around wheel.
The CR 38 is typically used by the cyclist who cares about weight savings and wants a great climbing wheel. The CR 38 is going to be easiest for lightweight or new cyclists in regards to handling in cross-wind situations.
The CR 50 is the ideal all-around wheel. The depth will provide aerodynamics while still being responsive in windy conditions. This wheel is light enough to race and sturdy enough to ride thousands of miles. This would be a great wheel for road racing, criteriums, training days or fondos.
The CR 85 is great wheel if aerodynamics are the main objective. This wheel is a good candidate to put on a tri bike or to take with you to your local crit. This wheel will catch a bit of cross-wind and while it offers speed would be best on flatter routes then long climbs and descents.
20-24 refers to the front-rear spoke count. 20-24 spoke count works for most cyclists, however cyclists over 180 pounds should consider the 24-28 spoke count. The weight of 20-24 spoked wheel is 1520 grams.
24-28 refers to the front-rear spoke count. 24-28 is best for cyclists who weigh over 180 pounds. The weight of 24-28 spoked wheels is 1560 grams.
White Industries Hub
At the heart of every wheel is the hub and we use the best! American-made White Industries hubs utilize the best individual components to guarantee every wheel will run at optimum efficiency. Exquisitely machined titanium free hub body, American ABEC 5 level bearings, a hub shell designed for strength and perfect spoking ensures the highest performance and longevity. 11 speed shimano/sram means the the freewheel hub is set up to hold shimano or sram cassettes and we also offer campy hubs.
Clincher is a wheel that will hold a tube inside the tire. The tire has a bead and that bead is hooked under a lip on the rim. Clinchers can be set up tubeless. Tubeless means the tire can hold sealant. Our wheels will accommodate both tubeless and tubes. Although, clinchers are the easiest to fix on the road and are the most inexpensive choice, more road cyclists are moving towards tubeless to reduce or eliminate flats. We offer both choices so you can decide what works best for your style of riding.
Tubular is a wheel where the tire encases a tube completely and is sewn in. The tire is glued on to the rim. The tubular wheel does not have a lip. Tubular wheels can be the least rolling resistance but can be costly when they seperate or flat. Tubular wheels are most commonly used on the track or by professionals who can get a full wheels change.
Tubeless is a tire that is seated on to the rim of the tire. It has sealant inside the tire to help prevent punctures. The tire is seated by the pressure of air in the tire. A tube can be placed inside the tire if there is a puncture that does not seal.
There are two options for braking on a road bike have both options covered. 1. Quick release QR better known as Quick Release can be used for all road bikes set up with regular caliper brakes. Our Brake Surface on carbon clincher wheels is 12 mm.
2. Disc Brakes We offer two sizes of wheels for Disc brake bikes-CR38mm orCR50mm. Wheels with disc brakes have Thru Axles and you need to select what size "Thru Axle diameter" you have on your bike-most common for road bikes is 12mm front and back, but occasionally you will see a 15mm thru axle on the front. Thru axles are frame specific, not hub specific, so you may need to check with your local bike shop or bike manufacturer to confirm.
15mm is usually set up for Cross/Mtbs (front). 12mm is usually set up for road bikes (front and rear).
Swisstop Black Prince Brake pads and Ti Quick Release Skewers are included with all road clincher models.
