Wheels

Kids wearing out their Strider? That's a good thing! Upgrade their out-of-doors adventures with these aluminum wheels. These lightweight 12-inch wheels are a great upgrade for trail riding and come with tires and tubes.

Zipp makes the impossible possible with their 303 Firecrest Carbon Disc Brake wheels—they're equally at home on the flats as they are in the mountains. The 45mm-deep rims slice through the wind more efficiently than even many deep-section wheels thanks to their 28.5mm-wide dimpled rims. And, by creating a seamless junction between rim and tire, the increased width further reduces drag. The 303s climb with the best and re-accelerate out of corners like rockets since they barely register on the scale, which makes them a must-have on undulating terrain. The extra wide rim also allows running wider tires at lower pressures with less fear of pinch flatting, which boosts ride quality and comfort and reduces rolling resistance. Plus, Zipp's 77D/177D disc hubs gives you incredible stopping power in wet and dry conditions alike, and they're thru-axle compatible (sold separately) for jaw-dropping steering precision and power transfer. You also get Sapim's oustanding CX-Ray spokes.

• Strong Custom Strider Rim • Durable No-Flat Tire • Tread pattern and bearings matches the ST-4, and will fit on any ST-Model

Just wide enough, just light enough. At 30mm internal rim width the M 1700 SPLINE 30 works for tires ranging from slightly wide to quite wide, allowing it to attack the hardest terrain. But with a high-end build, butted spokes, patented alloy Pro Lock nipples and the benchmark Ratchet System hubs, it still comes in at a low weight. Low weight means it's very reactive to rider input. Reactive means fun, and fun is why we are all doing this, right?

Unsure what will happen on your group ride? Mountains, hills, or flats? Water from below, water from above? You needn't worry, the PRC 1400 SPLINE 35 has it covered. High-end, bladed straight pull spokes and the most reliable and lightweight freewheel system make for an efficient ride. Offering the perfect blend of comfort, grip, and low weight in combination with a higher volume tire, these wide and stiff full carbon rims accelerate with the best of them.

In order to answer the call from Nairo Quintana and the other champions, Campagnolo created the Bora Ultra 35: perhaps the best wheel out there in terms of performance both while climbing and on mixed routes. The Bora Ultra's innovative AC3 (All Conditions Carbon Control) Technology means maximum safety when braking in any condition, providing shorter stopping distances and excellent braking modulation. And, thanks to its wide, aerodynamic profile, differentiated hub diameter, and CULT bearings, all cyclists can now enjoy the same performance Campagnolo provides its Pro-Tour champions. - 35mm carbon profile offers maximum lightness and aerodynamics - Designed for domination uphill and on the flats - CULT bearings deliver up to nine times the smoothness of standard bearings and are designed to resist oxidation, preserve performance over time - Carbon rim and hubs ensure good stiffness and extremely low weight - Aerodynamic profile spokes slice through the air - Exclusive G3 spokes ensure better balancing of the traction force on the wheel, drastically reducing all its stress - Weight: 1,360 grams

With even the EWS race courses getting tougher and tougher and tire manufacturers offering Enduro-strong tires in 2.5-inch sizes, the demand from DT's pros for a wide, Enduro tough wheelset came up and DT responded by developing the EX 1501 SPLINE ONE 30. Often used as a front wheel to generate as much grip where you need it most, it is the wheel for those hunting after the toughest of tracks or those living right in the Alps. Strong, lightweight, and tough as nails, the EX 1501 30 is ready for just about anything.

What It Is A climbing wheel with an aero advantage designed to be ridden in the mountains. Who it's for Road cyclists who require maximum versatility for riding in mountainous terrain and variable weather conditions. Why we made it Since the introduction of the original SES 3.4, we’ve implemented new design concepts across the SES lineup that result in a faster wheel and improved ride experience. The SES 3.4 features road tubeless compatibility, 25mm tire optimization, molded carbon brake track technology, and optimized SES aero rim shaping to ensure maximum efficiencies for a shallow aero wheel. Equally at home in the mountains as in the valleys, the SES 3.4 is the most versatile Smart ENVE System aero wheel. Like all SES wheel models, the SES 3.4 features dissimilar rim shapes and geometries between the front and back wheels to maximize aerodynamic efficiency and rideability in variable wind and weather conditions. The front rim is 38mm deep and shallower than the rear rim to aid in crosswind stability while rear rim is 42mm deep and therefore improves overall airflow. For riding in mountainous terrain where heavy braking is required, the SES 3.4 features a high-temperature-resistant resin system and ENVE's molded-in brake track technology to ensure rim integrity and precision braking when and where it is needed most.

After designing the CLX 50s, we realized that an affordable, race-worthy carbon wheelset was nowhere to be found—until the CL 50 was developed, that is. We paired our quiver-killing CLX 50 rim with DT Swiss Competition round spokes, our Aero Flange hubs with DT Swiss 350 internals, and steel bearings to deliver you an exceptional wheelset at a more than accessible price. Sharing rims with the CLX 50s, the CL 50s feature many of the benefits as their higher-end siblings. Even though the CL 50 is similar in weight to many wheels in the “lightweight” category, aerodynamics came at the forefront of the development. With this, we jumped headlong into Computational Fluid Dynamics computer modeling to arrive at various rim shapes that could make the CL 50 as fast and light as possible. It took a while, but we narrowed the rim shape down to three contenders that were then CNC machined into rims, built into wheels, and put into the Win Tunnel. In the tunnel, we tested every wheel, ours and the competition's, with a 24C tire (measuring 26C), as tires can drastically affect testing. We chose a modern-width tire to design our rims around, because they not only allow for less tire pressure (which results in more comfort and less rolling resistance) but are also just as aerodynamically efficient when paired with the correct rim width. Now it was time for final testing validation. The result? A 50mm-deep, 1465-gram clincher wheelset that's race-ready and wallet-friendly. - Rim Type: Carbon clincher, 2Bliss-Ready - Rim Material: Carbon - Braking Surface: Carbon Fiber - Brake Track Height: 12mm - Rim Depth: 50mm - Rim Width: 20.7mm internal, 29.4mm external - Front Spoke Pattern: Radial - Rear Spoke Pattern: Radial/Two-cross (2:1) - Spoke Count: 16 front, 21 rear - Spoke Type: DT Swiss Competition Race T-head - Nipple Type: DT Swiss Pro LockBrass hexagonal - Front Hub: Roval AF1, sealed cartridge bearings - Rear Hub: Roval AF1, sealed cartridge bearings, DT Swiss 350 internals, 11-speed - Assembly Method: Hand-built - Extras: Roval steel quick-releases, Roval tubeless plugs and valves, SwissStop Black Prince brake pads
