Narrow is Aero

Based on the concept that Narrow is Aero, everything on the Slice RS, from the radical steerer-less fork to the windshadow brakes to that crazy looking seat post, is designed to minimize the surface area presented to the wind.

It works so well that the Slice RS can save up to 20 seconds in 40k compared to our competition. And with features like our AERO SAVE anti-vibration technology, and CFit modular fit system, it’s a time-slicing machine that’s as comfortable as it is aero.

Slice RS is:

  • Narrow cross-sections reduce drag and increase speed.
  • Class-leading lateral stiffness provides efficient power transfer and rock-solid handling.
  • AERO SAVE technology reduces vibration and cuts fatigue.
  • Huge range of stack and reach combinations for a perfect fit.

Rider Profile:

This UCI-legal rocket is built for time-trial specialists or triathletes looking for the absolute fastest way from point A to point B.


  • Updated Naero-Tec External Steerer Fork
    The dual crown, external steerer design of the fork allows for an incredibly narrow headtube for reduced drag, while being extremely stiff for precise handling. For maximum aerodynamics, the updated stem design features a hidden compartment for Di2 components.
  • Integrated Aero Handlebar
    The new ultra light Vision base bar integrates cleanly into the stem and allows fully internal brake cable routing, right through the stem and headtube.
  • Thru-Headtube Internal Cables
    Shift and brake cables are routed through the top of the stem and into the downtube for a clean, super aero set-up.
  • CFit modular fit system
    The modular bar/armrest adjustment system allows for a larger than normal range of aero position adjustment.
  • WindShadow Brakes
    The integrated brakes are hidden in the windshadow of the fork and BB. The modified V-brake design is simple to adjust and provides tons of stopping power.
  • NaeroTec Seatpost
    The thinnest UCI-legal seatpost ever made. Its tiny frontal area reduces drag and prevents disturbed air from the rider’s legs from interfering with the aero performance of the frame.
  • WindTunnel Pressure-Drag Reduction Tunnel
    The seat tube directs air smoothly over the rear wheel. The WindTunnel channel behind the seat tube reduces the pressure drag caused by air packing up between the spinning wheel and the frame.
  • AERO SAVE anti-vibration system
    AERO SAVE seat stays absorb shock, reducing fatigue and enhancing control. The Slice RS boasts the same vertical compliance as our EVO road frame.
