Ruote Bici da Corsa Elitewheels Drive Helix 46D SS

The Elitewheels Drive Helix 46D SS have steel spokes and were designed to be the ultimate climbing wheelset. These Elitewheels Drive Helix 46D road bike wheels are extremely light at 1345 grams. You'll have the advantage of a wheelset with high rims in terms of rigidity and power transfer, as well as the advantages of low rims in terms of increased wind stability thanks to the specialised high-low rim profile.

The Surface hubs contain ceramic bearings made by the Taiwanese TPI brand. These bearings have an extremely low rolling resistance and good durability. They're well-sealed from water and dirt, and come with a Star ratchet freehub body system. This system engages quickly and is commonly used on Elite Wheels MTB and time trial wheels.

The width of the rims varies between the front and rear wheel. The wider rim on the front wheel improves airflow and stability, which the rear wheel helps drain away this airflow. It's almost hard to believe that Elitewheels has created a wheelset with such a great mixture of rigidity, wind stability and low weight. This is especially useful on high-speed descents, when the stability of these rims is maintained.

Stainless steel spokes
Lightweight Sapim CX-Ray aerodynamic spokes are excellent in terms of performance and rigidity, though they weigh only 4.4 grams a piece. These spokes are special: they're available worldwide and are trusted and used by professional road, gravel and MTB riders all over the world. They've proven their value and in terms of steel spokes, Sapim CX-Rays are simply the best.

Rims
The Drive Helix 46D wheelset was perfectly designed to meet the demands of modern road cyclists. They're aerodynamic, lightweight, rigid, strong and stable in lateral winds: everything you need to push your speed and performance to the next level. Consisting of a mixture of Japanese Toray T700 and T800 carbon fibres, these rims are optimally balanced for rigidity, weight and strength. Their patented wave shape was inspired by nature and improves their stability in windy conditions. These wheels are optimised for 28-30 mm tyres. The wide rim on the front wheel improves airflow and stability, while the mixed height of the front and rear rims combines aerodynamics, low weight, and improved control over your bike.

Surface hubs
Surface hubs are designed and produced with 0.02 mm tolerances, to guarantee a perfectly fitting bearing. High-end TPI steel bearings were chosen to improve lifespan and to reduce rolling resistance. TPI bearings are precise and have a low rolling resistance, and are even compatible with some ceramic bearings.

Star Ratchet system
Like other hubs, the Surface hub is produced using a 5-axle CNC machine. This Surface hub is unique because of its Star Ratchet engagement system, which has been used on mountain bikes and time trial bikes for years.

Aerodynamic tests
At Elitewheels, they know it's important that wheelsets feel as good on the road as they look in the aerodynamics test results. Aside from performing more than 20 laboratory tests in the factory, Elitewheels also used CFD (Computational Fluid Dynamics) tests, and racing tests with professional cyclists and teams. CFD tests help aerodynamically optimise wheels before the first prototype is even produced. During the design phase, a number of advanced computer simulations were performed, of hundreds of hours each. After the engineering team is satisfied, the wheels are ready for stress tests in the laboratory. Then, after the design phase, the wheels weren't just tested by Elitewheels themselves: they were also sent to professional cyclists. Elitewheels collaborates with sponsored, continental professional teams and UCI cyclists, and gets feedback from them. Their experience, combined with their hundreds of thousands of kilometres of cycling with these wheels, provides Elitewheels with a unique perspective.
