  • What is an OSYMETRIC curve?
    OSYMETRIC curve is not an oval or ellipse, is a dual cam, a TwinCam.
    What is a Twincam : 2 curves are symmetrical about a single point. 
  • Why is OSYMETRIC not an oval or ellipse?
    Neither the ellipse or oval and can solve the optimization of the strength of the leg using a crank.
  • How much wattage can we expect to gain with OSYMETRIC?
    Whit OSYMETRIC you gain on average 10% in watts, you can easily check with : SRM, the POWERTAP, or ERGOMO, and numerous studies have shown.
  • What is the speed with OSYMETRIC?
    The angular velocity of OSYMETRIC is almost constant, therefore no impact from the changes in angular velocity.
  • What makes the transition between bike and running  so easy with OSYMETRIC?
    Pedalling using OSYMETRIC produces less lactic acid 12% thus enabling you to run much faster.
  • What is the adjustment period with OSYMETRIC?
    95% of cyclists get use to it within an hour.
  • What is the cadence of pedalling with OSYMETRIC?
    Given the reduction in torque/effort required there is less need for faster cadence???
  • What happens if i return to normal chain rings?
    You will return to your previous performance.
  • Why OSYMETRIC which seems so effective is not used by all the Pro Teams?
    For a simple matter of budget..
  • OSYMETRIC requires there a special chain?
    No, but we would recommend a good higt quality chain.
  • OSYMETRIC is it louder?
    Yes, the sound of the chain on the relatively "flat" is a little bit noisy (use good quality oil to reduce this).
  • OSYMETRIC is there a chance the chain falls off more frequently?
    No, otherwise the PRO MTB (Fabien Barel, Nicolas Filippi, Nicolas LEBRUN, Sybille Matter, etc..) would not have adopted these.
  • OSYMETRIC is it resistant?
    Yes, for the same reasons as above.
  • OSYMETRIC it is easy to assemble?
        Yes, relatively but please request details of mounting a chain ring?
  • OSYMETRIC it is interesting to mountain biking?
    Yes, the human motor is more important because of the constant torque.
