The Surly Tuggnut (it's a tug nut) is designed for rear-facing horizontal dropouts (otherwise known as track ends), like those found on the Surly ECR, or most track bikes.

  • The body is investment cast in stainless steel for durability.
  • Features a thumbscrew and two axle holes for a wide range of fore/aft wheel positions.
  • It'll work with both quick-release and nutted axles.
  • It has a built-in bottle opener ;-)
