The second generation Velocite RT50 aero road tubeless wheels are a product of two years of research and development and rider feedback. The unique 50mm tall and 25mm wide rim profile was developed using proprietary CFD (computational fluid dynamics) simulations and was designed to deliver minimal drag and zero steering torque in cross wind situations.
The combination of safe crosswind handling, tubeless tire puncture resistance (when sealant is used) and low wind resistance means that you can ride with confidence in a wide range of real life riding or racing situations.

Velocite RT50 aero wheels are delivered taped for road tubeless use, with a brass tubeless valve and an alloy extension. The wheels can also be used as standard carbon road clincher wheels when used with non-tubeless tires after removing the valve.
Velocite RT50 wheels utilize our ZeroTorque™ airfoil design which effectively eliminates steering torque as a result of cross winds. The simulated peak torque value at 22° angle of attack is just 18 grams of force (simulated at 30 mph / 48 km/h).
This means that when riding in blustery or windy conditions your steering will not be affected. You will still experience the side force, but not the twisting of your front wheel. This will deliver enhanced confidence and speed as you will be able to remain in your aero position on the handlebars.
The ZeroTorque airfoil performs very well when it comes to drag as the results show. The total drag decreases beyond 6° angle of attack, all the way to 22° indicating a very late aerodynamic stall and good performance in very strong cross wind situations.
The rim shape was developed using custom developed novel computational fluid dynamics software that is able to simulate rotating wheels directly, and with greater accuracy than ever before. You can read more about the development process in our blog.
The primary criteria for the RT50 rims was to ensure their stiffness, durability and resistance to high temperatures. To achieve this we used an advanced layup that ensures stiff rim sidewalls and a custom developed resin system which offers both high bonding strength (measured as interlaminar shear strength) and resistance to high temperatures. The rims are temperature stable at up to 192º C (377º F).
Since the Velocite RT50 are true road tubeless wheels, the rims have sophisticated internal rim locking features designed to lock the tire bead firmly onto the rim and thus provide an airtight seal. The seal is airtight even at low air pressures that may result as a restult of a puncture, or during initial inflation. This means that, once mounted, you are able to inflate or reinflate the tires with ease as they will not come off the rim without further physical force which is needed to unseat the tires from the internal bead locking features.
The additional feature is a seamless brake track that is integrated into the rim profile allowing more even carbon fiber layup with better mechanical stress distribution. The rims are precision CNC drilled to achieve the correct spoke angles to reduce any bending stresses on the nipples
The wheels are assembled by hand using stainless steel bladed spokes, Wheelsmith Spoke Prep™ and long rounded collar alloy nipples. The building process involves three tension and de-tension cycles, followed by computer controlled quality assurance certification - the QC measurements obtained are included with every wheel.
The Velocite RT50 performance is further helped by the advanced Velocite Gram triplet (2:1 lacing) hubs. The high precision construction combined with part integration design philosophy deliver exceptionally low rolling and coasting resistance, very high peak load values and stable and laterally stiff wheels. The minimal part count also allows easy maintenance and service.
The wheels went through a rigorous testing and development process, both in field with our test riders and on some of the most advanced computer controlled test machines available.
