Ever stomp on the pedals just to have your rear wheel slide forward in the dropouts and throw your chain? There are lots of BMX-style tensioners out there, but few of them fit in Surly's dropouts without some serious grinding. So, Surly designed a chain tensioner that will keep that rear wheel static in their dropouts...and most other kinds of rear-facing horizontal dropouts. Plus, the Tuggnut will open up a bottle o' brew. The body of the Tuggnut is investment cast in stainless steel for durability. It features a thumbscrew, for tool-free adjustments, and 2 axle holes for a wide range of fore/aft wheel positions. The Tuggnut comes with an aluminum adapter that reduces the axle hole from 10mm to 6mm, so you can use it with quick-release axles, in addition to nutted axles. It is sold as a single, because you really only need one...on the drive side. But, if you absolutely need one on the non-drive side of your rig, to achieve balance in your life, you are in luck...the bottle opener works either way.
