Realspeed RS55 Disc - DT Swiss 240
Through all that we have learned from our original RS5/6 model, we have identified that the most balanced profile is 55mm. Even though the RS5/6 staggered profiles of a 50mm front and 60mm rear wheel provided some compelling performance. Overall, the 55mm rim profile provided what we believe is the most optimized depth for peak aerodynamics at a multitude of different yaw angles. When rim depth increases past 60mm, they are faster at more closed angles but less efficient at wider yaw angles. The 55mm depth also provides less of a weight penalty, resulting in a perfectly balanced aero focused wheelset, with little compromise.

PIVOT RIM CONSTRUCTION
The RS55 rims feature Pivot hookless technology. With the use of a mandrel during the manufacturing process, construction accuracy is greatly improved, resulting in a stronger, and lighter rim. The hookless bed of the rim also allows for improved tire performance based on how the tire is attached to the rim. Its shape is more efficient, thus improving rolling performance, but also more aerodynamic, as the tire is more seamless to the transition at the rim.
The RS55 features updated graphics, that have reflective properties, improving low light visibility for the rider.
55MM RIM PROFILE
The RS55 features a 55mm depth rim profile. Through rigorous testing in the wind tunnel and on the road, we have discovered that 55mm is the perfect depth to not tip the scales, and provide a significant increase in aerodynamic performance.
EXTRA WIDE 25mm RIM WIDTH
The extra wide 25mm external width and 21.5mm internal width of the RS55 provides a better interface for the tire, resulting in improved tire performance.
DT SWISS 240 HUBS
The RS55 DT240 are built with the latest generation of the 240 hub from DT Swiss. The strengths have been further enhanced. The latest DT Swiss Ratchet EXP® freehub system increases the bearing lifetime thanks to the increased bearing distance. The hollow-machined ratchets transfers the energy invested directly into acceleration thanks to the 36 teeth.
