This Osymetric MTB Chain Ring is no longer available although you may find similar or newer versions below:
The newly designed Osymetric MTB Outer chainrings are designed to enhance a riders power output and performance by eliminating their dead spot during each pedal stroke. Catering for the serious MTB rider, they are available in various chainring sizes.
Get up those tough muddy climbs faster and save power in the process. These Osymetric chainrings are not the standard 'round' type of chainrings nor are they oval or ellipse either, but asymmetric. This unique shape (twin-cam) has been designed to maximize the riders power output and performance with every pedal stroke allowing for a 7-10% power (watts) increase resulting in a gain of speed by 3%, so Osymetric claim. Not only does this increase riders performance it can reduce lactic acid by 10% also.
Picture shows Osymetric chainrings fitted to a Road bike.
Once fitted, getting used to these chainrings will take a few rides or so and your legs may feel sore after the first ride, but this is natural due to the chainring shape and the different muscle groups used during your pedaling. Once adapted though, the benefits and gain are great as you have increased you power and speed by actually doing the same if using standard chainrings. Plus your legs are benefiting from less lactic acid being produced making you ride faster and harder longer.
Installing these Osymetric chainrings is straightforward - similar to fitting standard rings. You'll also have to raise the front derailleur setting your upper and lower limits to compensate the mech movement. Please follow the instructions that come with the chainrings or watch the video located on the video tab above the image. Or simply pop down to your local bike shop and ask them to fit for you. We would also recommend that you fit a new chain also.
