Rene Herse knows many people enjoy the simplicity of a 1x setup and they also know that square taper bottom brackets allow for fine chainline adjustment, something modern 1x cranks do not offer. These are the reasons for their new 1x cranks. A 113mm BB will give you the same chainline as modern road cranks. If you need extra room because your bike has very wide chainstays, go to a 116 mm spindle, or even wider, all the way to 126 mm. These options will keep your chainline happy and minimize wear and tear on your components.
It doesn’t stop there. These cranks come in a dedicated 1x setup or cranks that can run a 2x or 3x rings as well.
