Introducing the Real Speed RS 3/4. The result of hours in the windtunnel that takes versatility to another level. The RS 3/4 is light enough for the steepest of climbs but still boasts legitimate aerodynamic performance to increase speed while maintaining exceptional stability. Available in rim brake and disc brake formats.

The RS 3/4 features staggered rim depths, which delivers an optimized balance of aerodynamics and overall stability. The front and rear wheels react differently and that is primarily due to how they are exposed to the wind, along with the front wheel being hinged and the rear being fixed. The yaw angles which the front wheel are subject to are vast and change more frequently. Through our development, we have discovered that a shallower front rim, and deeper rear rim is most efficient. The RS 3/4, depths have been revised to 35mm at the front and 45mm at the rear.

The external widths of the RS 3/4 are 27mm for the front and 28mm for the rear. This combination is set for optimal aerodynamic integration with a 25mm-28mm tire. The stagger also plays an important roles in maximizing the performance of the tire, providing more comfort, reduced rolling resistance, and improved grip.

FEATURES

 

  • Staggered rim pairings:

  • The new RS 3/4 wheels feature staggered rims. The depth of the front and rear wheel are different, we Identified where improvement can be made to the overall shape of the rim to enhance the efficiency when yaw angles open up. The external widths of the RS 3/4 are 27mm for the front and 28mm for the rear. This combination is set for optimal aerodynamic integration with a 25mm-28mm tire. The stagger also plays an important roles in maximizing the performance of the tire, providing more comfort, reduced rolling resistance, and improved grip.

     

     

  • Rock solid reliability

  • Singular Moulding, our rim is made by using one piece construction. No partitions, no seams. This maximizing structural integrity.The RS 3/4 also features an asymmetrical profile which allows for equalized spoke tension and creates a stronger wheel that stays true. Furthermore, angled spoke holes at 7 degrees allows the nipple to pull straight in line with the spoke for reduced stress. This results in fewer broken spokes and nipples.
  • Hand Built:

  • As always, all our Realspeed wheels are hand built in Canada with precision and great attention to detail. We use Belgian CX Ray spokes and nipples, along with your choice of Realspeed Japanese bearing hubs, or DT Swiss 240s hubs. All our wheels are built and quality control tested to the highest standards, ensuring that you are getting the perfect set of wheels that will provide many seasons of reliability and performance.
  • volcan technology:

  • The amount of effort we placed on improving aerodynamic efficiency we equaled to improve braking performance. For the new 3/4 and 5/6 Wheelsets, we chose to build the rims using prepreg carbon fiber, which is carbon that already has a high TG resin impregnated into the material. This allows for more precision when shaping the rim, reducing the amount of material and resin being applied to reduce weight and heat retention. Our New VOLCAN braking surface uses a Basalt finishing treatment, which is a naturally fire-resistant hard and dense volcanic rock to minimize heat buildup and improve overall stopping performance.The result is a rim that is provides a high rate of heat dissipation under heavy braking loads, maximizing the performance of the wheel.
