Wolf Tooth Components saw Cyclocross as the perfect discipline for use for their Drop-Stop technology, and that's why they went to market with Cyclocross 1x specific chainrings. The use of these rings expanded to allow for more options. With the Drop Stop 5-Bolt SRAM Flattop Chainring, Wolf Tooth used their Drop-Stop tech and alternating wide and narrow tooth patterns to prevent chain derailment and reduce friction. Sizing choices come in even-numbered teeth from 30 all the way up to 50, and two BCDs.
