Elliptical 104 BCD Chainring Drop-Stop® A

Chainrings by Wolf Tooth profit from their developers’ great passion for biking and their love of tinkering. What’s more, these people have put their long-standing experience in precision technology and fine mechanics into the products.
Wolf Tooth Narrow Wide Chainrings are tried and tested during biking and racing in the challenging conditions around the company location in Burnsville, Minnesota, where oppressive, dusty heat alternates with frigidly cold winters. These bike components stand out with their excellent performance and chain guide.

With the oval PowerTrac Elliptical™ (PTE) chainrings by Wolf Tooth, you will experience less fatigue and ride longer and faster because you will use your power more efficiently. The Elliptical chainring varies the resistance during pedalling according to the natural strengths and weaknesses of your legs. The smaller diameter of the oval is directed towards the weakest point of your power input and the larger one towards the strongest point. In this way, the most productive part of your pedal stroke is used optimally, whereas the time is reduced for the less productive part. This makes your pedal stroke feel much smoother than with classic, round chainrings.

The Elliptical 104 BCD chainring by Wolf Tooth fits any crankset with symmetric 104 mm bolt circle and uses the proven Drop-Stop® technology.
