THINKING OUTSIDE THE BOX
The Asymm disc wheel range have an Asymmetrical cross section profile developed by Revolver. This breakthrough in design came together by going back to the drawing board and re-designing each side of the wheel independently. The result of this process is a wheel with completely different shaped ‘drive’ and ‘non drive’ sides, both using lenticular profiles, but in different ways within the confines of the practical space available. Built using a very light donor sub wheel which is then strengthened by fully bonded Carbon Fiber structural disc skins creates a wheel with the comfort of a regular road wheel which can be ridden for hours without the buildup of vibration fatigue, making it an ideal choice for longer events such as Full and Half Iron distance Triathlon.
WHY GO WIDE?
Most modern wider rim race wheels developed in recent years allow for the use of faster rolling (lower Crr) wider tyres but there’s usually an aerodynamic trade off to consider. The 2020 Asymm is available in two rim options – ‘Regular’ with a wide 19mm inner bead track recommended for use with 23mm or 25mm tyres for optimal aerodynamic tyre to rim interface and ‘XWide’ with a market leading 21mm inner bead track recommended for optimal use with 25mm or 28mm tyres. Note that frame and brake clearances must be taken into consideration when thinking of going XWide with Rim Brake models.
ASYMMETRICAL PROFILE
The drive side of the Asymm has our Wave Lenticular Profile comprising of a wide central lens area that flows seamlessly into a deep toroidal bulging outer rim designed to work best with wider 23mm, 25mm and even 28mm tyres . Wider tyres have less rolling resistance and when combined with our aero optimised flared brake track are without aerodynamic penalty. This sophisticated design out performs all flat sided discs in any angle of yaw while still allowing full use of all cassette options including 12 speed.
The non-drive side of the Asymm is completely different. A deeply dished perfect lens that makes full use of the lateral space available, greater here due to the lack of a drivetrain system. This is the ultimate shape for a wheel out performing any other at all Yaw angles and is currently only seen on the very best track specific discs wheels available such as those used by Team GB.
The combination of these profiles, both the ultimate shape for purpose, a rim designed specifically for wider faster rolling tyres and our vibration soaking construction method produce a wheel with unparalleled all round performance. Quite simply the fastest TT/Triathlon specific wheel available.
