REVOLVER KRONOSTOK FWS 7 (2020)

RIMS – LIGHTER BY DESIGN

Lighter in construction due to the use of the FWS manufacturing method.  Filament Winding System (FWS) involves winding a band of carbon fibre filaments around a 3D mould while building up rim thickness gradually and evenly resulting in a more balanced strength within the entire rim.   Adding Graphene increases impact resistance further and dampens road vibration.  High glass transitional temperature (hiTg) epoxy resins  are used in place of regular epoxy resins and are cured at higher temperatures resulting in greater elimination of minute air pockets within the rim structure, reducing weight, increasing stiffness and  impact strength as well as a brake track with a Mohs hardness of 10.  All Kronostok FWS rims benefit from our ‘Arc Dispersal Track’ (ADT),  CNC machined curved slots which increases braking modulation in the wet by reducing rim surface water build up while assisting heat dispersal under dry braking.  This innovation improves breaking performance by around 20%.

AERODYNAMICS – WITHOUT GIMMICKS

Aerodynamically these rims are top performers featuring a wide 25mm to 26mm flared brake track  and a generous 19mm internal track which when fitted with a 23mm or 25mm tyre creates the perfect aero interface needed to penetrate the air with minimal drag.  A blunt rounded inner edge profile creates a balanced overall shape that is incredibly aerodynamic and remains efficient even at higher Yaw angles while maintaining superb handling characteristics, working to your advantage whatever the conditions.

HUBS – DT SWISS

When choosing a hubset we can’t look beyond the Swiss giant.  The clue to the quality is right there in the name and with years of trouble free  experience building with them why change?  A choice of two models are available, the mid range 350 Straightpull and the Pro/Elite benchmark 240 straightpull set.

*DT SWISS 350, one of the best mid range hubsets available sharing features with its big brother the 240 model.   Excellent quality and renowned for its  durability as you’d expected from one of the worlds biggest brands, making it the most popular hub choice throughout our range of builds.

*DT SWISS 240, in our opinion one of the best hubsets money can buy.  A benchmark within the industry due to its legendary durability and ease of servicing.  Widely used within the Pro/Elite ranks of Cycling and Triathlon as well as being the turn to hub for many of the biggest wheel brands around.

SPOKES

An area not to be overlooked when considering overall performance.  All Kronostok FWS wheelsets are laced with Sapim CX Ray spokes and sils brass lock nipples.   With a reputation as one of the strongest spokes available the CX Ray also boasts unrivalled aerodynamics and corrosion resistance.  The number one choice for a fast durable wheelset.   Simply the best spoke out there.

THE SIGN OF QUALITY

We’re committed to building reliable durable wheelsets, which is why all Kronostok FWS models have undergone and passed the rigorous testing procedures necessary to be awarded UCI approval.  This allows their use in all UCI (road), ITU & ETU (Triathlon/Duathlon) drafting events which has become increasingly important to many Age Group Triathletes as well as competitive road riders.
