Surly Tuggnut Chain Tensioner
Ever stomp on the pedals just to have your rear wheel slide forward in the dropouts and throw your chain? We have....using all kinds of hubs in all kinds of frames. There are lots of BMX-style tensioners out there, but few of them fit in our dropouts without some serious grinding. So, we decided to design a chain tensioner that will keep that rear wheel static in our dropouts...and most other kinds of rear-facing horizontal dropouts. Plus, ours 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. We sell it 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.
Chain devices fit in various places around a mountain bikes transmission and help to eliminate chain suck and chain slap when riding over rough terrain or landing from big drops. There are a number of fitments, some frames have ISCG mounts which are lugs on the drive-side of the bottom bracket shell and allow direct fitment to the frame, other chain devices fit in between the bottom bracket and frame and require a specific bottom bracket with a larger drive-side cup, and finally there is the type that clamp around the seat tube in place of the front mech. Also within this section you can find single speed chain tensioners which fit in place of the rear mech and take up any chain slack.There is also a selection of wheel tugs which stop you pulling your wheel over in horizontal dropouts.
