Benefits

The OSYMETRIC ring is not an oval nor an ellipse – it is a twin cam shaped to win. This patented design reduces the gear and the effort needed to get through what is commonly called the “dead spot” in everyones pedal stroke. Then it increases the usable gear during the power portion of the pedal stroke between the 1 and 5 o’clock positions of the crank so your body can take full advantage of its natural strength. This powerful tool can reduce lactic acid by 10% and increases power by 10% for anyone that uses them. With OSYMETRIC chainrings installed properly on a bicycle, one can expect a gain of 7-10% watts. Interestingly the rings are most beneficial the closer your are to your personal anaerobic threshold. This can be easly confirmed with testing on an SRM, POWERTAP or Quarq power meters.

Please take some time to review some of the testing that has gone into proving the Osymetric Chainring is an advantage.

Are the OSYMETRIC rings only for time trialing?
No, although they are great for time trialing, riders using them have medaled in the Olympics, World Championships, National Championships as well as victories in the Grand tours. They can be ridden on all types of bicycles and in all types of events. They are UCI legal and this year(2011) some of our top riders have already won some crazy field sprints in Paris Nice and did you not see Greg Henderson win the TOC stage into Modesto?
Are OSYMETRIC chainrings beneficial for Triathalons?
Pedalling using OSYMETRIC chainrings produces 12% less lactic acid enabling an athlete to run faster and longer after getting off the bicycle, the oval shape mimics the way a human walks or runs for a more efficient and powerful pedal stroke. This biomechanical advantage makes for an easier transition to the running portion of the triathalon because don’t feel like your legs just want to pedal when you hit the pavement for the run.
How long will it take me to get used to riding with OSYMETRIC rings?
95% of all cyclists can transition to OSYMETRRIC rings in as few as 2 or 3 different rides. Your legs may be even a bit sore after the first ride. That’s because you are pulling in some other muscle groups. They are not for everyone but for those that choose to use them after they get used to them the benefits are more than just anecdotal.
