Overview

The CA5.0 is back with a vengence. After 4 years of missed deadlines, delays and manufacturing issues, we are finally satisfied and proud to show the new CA5.0. A methodology that has since been abandoned by many brands as it interfered with their full carbon clinchers and their inability to reduce the weights of these wheels, but pushed by us beyond the performance of anything comparable. The CA5.0 is wider, stiffer and lighter than anything else with the same construction in the market.

A host of new features adorn this wheelset, namely a completely new rim shape with the FOILX profile, a new aluminium alloy extrusion that is optimised for the bonding of the carbon fairing, new layup to reduce the weight of the rim and to allow the use of a UD finish in a rounded profile, something not even big wheel brands are able to achieve as most wheels of this construction are in 3K. The new shaped rims allow for a better and smoother transition with clincher tyres. It also creates a smoother ride as tyres can be run at lower pressures. The wider rim improves airflow between the tyre and rim junction and the flared rim improves laminar flow reducing separation and thus reducing aerodynamic drag. FOILX  increases the stability of the wheels in crosswinds and reduces the aerodynamic drag of the wheel at greater yaw angles by equalising the ‘head’ and ‘tail’ of the profile. As side winds hit the curved and foil shaped sidewalls, it does not push on it causing the rim to deflect but rather moves gradually around the surface.

If there is one carbon wheel that we recommend for an all purpose budget carbon wheel, it is the CA5.0. The aluminium rim provides rigidity and stiffness where it is needed, stable braking performace and heat management and the carbon fairing stiffens the entire rim as well as provide an aerodynamic shape without a significant increase in weight. At 1615g, it sits comfortably below the S4.0 while providing an additional 5mm of depth to the profile. You get the best of all worlds with this wheelset, aluminium wheel price, braking performance and durability and carbon wheel weight, aerodynamics and looks.

The placement of nipples at the aluminium section alloys for a higher spoke tension and increase in stiffness for all those out of saddle efforts yet allows for a much lighter rim.

Built stiff, durable and aerodynamic, these are a perfect alternative to the full carbon clinchers if light weight wasn’t a priority.

The new R17 hubset features a new preloaded rear hub axle which is 17mm in diameter. The increase in diameter not only increases the torsional stiffness of the rear wheel, but at 17mm is one of the biggest rear axles for road bikes in the market. The 17mm axle doesn’t only mean it is stiffer, but it also means bigger bearings that are more durable, and spin smoother/ faster. The entire rear hub has been refined, using a ‘through axle’ pre-loaded on one side. Rear NDS flange has been increased in thickness to provide more support for the J-bend spokes again reducing twisting and premature fatigue. All new rubber seals are included for both the front and rear wheels to increase bearing life, something not seen at all in many hubs.

The wheels continue to use only 1 spoke length for the entire wheelbuild which makes self and off-site servicing simpler. The SOUL R-17 hubs feature a smoother freewheel design with 3 pawls , 48 teeth ratchet and 2 sealed bearings front and 4 sealed bearings rear. The 48 teeth ratchet where normally only 24 are used increases engagement speed to 7.5deg.  Fully artisan crafted and handbuilt with equal spoke tensions. Spoke threads are prepared before assembly to prevent spoke binding and seizing. All spokes are stress relieved a few times during build process.
