Overview

The S4.0 (2015) has steadily gained popularity due to it’s aerodynamic shape, relative weight, durability, stiffness and price/ performance ratio. It is completely new this year as we complete the revamp of our aluminium wheelset range with a new proprietary rim extrusion and mold. Using the experience we gained from developing the S3.0s, we designed an everyday aerodynamic deep section aluminium clincher wheelset and made them race worthy not just for triathlons, but also road racing. These wheels were developed with the idea of a deep section wheelset that is not made with carbon and can handle the abuse of everyday riding/ training. It also combines the ease of using a normal brakepad with the dependability of a clincher. The overall weight has been cut so much that you would think they were made with carbon and in fact are alot lighter than many carbon clinchers on the market.

The new wider, rounded and foil shaped rims are dubbed FOILX. This rim shape 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. FOILX 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.  So not only did we make it wider, we made it rounder, retained the depth and reduced the weight….. in some industries they call this magic. 10 years ago we couldn’t have imagined making something so deep so light, all the experience we have gained by listening to our customers, riding our wheels and persistently refining our designs which has led to the design of a wheel that no other brand in the world is able to replicate. Something truly to be proud of. At 1630g/pair it makes many shallower wheels look like boat anchors.

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.

Now you can buy speed for alot less and not have to worry about burning a hole in your pocket or your rims when you are descending that mountain. Don’t believe us? Read the review here.
