If you have ever wanted to try a “one-by”, single front chain ring set up, but own a Shimano, asymmetrical 110BCD crank set, now you have a great option to consider. Wolftooth, the USA made chain ring company located in Minneapolis, Minnesota, has just released an option to get your gravel rig set up as a “one-by”, front derailleur free rig. Check out their press release here:

That’s right: Wolf Tooth Components’ Drop-Stop one-by chainrings are now available for Dura-Ace, Ultegra, 105, and Tiagra cranks with Shimano’s asymmetric 4x110mm bolt pattern.

Beautifully machined from hard-wearing 7075-T6 aluminum, the 110BCD Asymmetric 4-Bolt chainrings take advantage of Wolf Tooth’s patent-pending Drop-Stop® tooth profile for unrivaled chain retention and mud shedding. The 38-44t even-sized chainrings are ideal for cyclocross, road, and gravel applications, bringing the advantages of quiet, lightweight, and secure single-ring drivetrains to some of the best and most popular cranksets on the market. Wolf Tooth Components designs and fabricates all Drop Stop chainrings in Minneapolis, Minnesota. Designed to be mounted in the outer chainring position, 110BCD Asymmetric 4-Bolt chainrings are offset for a 1x road-optimized 44mm chainline.

The chain rings are available now in 38T, 40T, and 42T with a 44T ring coming in mid-November. You can pick one up for $78.95. See the Wolftooth page for these rings by clicking HERE. Complimentary US-made single-ring-specific 6mm chainring bolt sets are also available in eight colors.
