Material.
An American company, based and manufacturing in Minnesota, that has made a name for itself by producing quality bicycle accessories and gadgets. In particular, their single-speed drivetrains covering most of the cranks available on the market, along with their seamlessness, durability and craftsmanship are already legendary.
However, Wolf tooth is constantly adding more and more unique products to their portfolio that are patented and handcrafted in the USA. Designed by the riders themselves, these "universal" parts often serve as an add-on to the mass-produced offerings of the major brands. With craftsmanship and attention to detail, however, they raise the bar for quality.
