The Surly Tuggnut Chain Tensioner is ideal for riders using frames with horizontal dropouts. The Tugnutt helps maintain chain tension with a handy adjuster. There are lots of BMX-style tensioners out there, but few of them fit in our dropouts without some serious grinding. This made Surly design a chain tensioner that will keep that rear wheel static in the dropouts and most other kinds of rear-facing horizontal dropouts. In addition, they also feature a bottle opener for when things get rad.
- 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.
