As much as I dislike the whole single speed “less gears more beers” vibe that I believe Surly is partly responsible for. And the whole single speed subculture of putting bottle openers on everything. I bought a Surly Tuggnut and it works sort of. It sort of kept the wheel from slowly sliding in the dropouts. Meh…
My single speed was making noise under hard pedalling. Which made no sense to a simple man like me who was preached the virtues of single speed and how it was maintenance free bliss.
Turns out my wheel was slipping a bit in the dropouts. My local bike shop had the Surly Tuggnut in and it fixed the problem temporarily . It fits over the axle (even includes a spacer for QR skewers), and you screw out the little stop to press against the back of the drop out (or track end if you are a stickler for semantics) to keep the wheel from slipping.
Two weeks later, and no slipping so I thought it was working.. One more week passed and it has slipped enough to be noticeable. Meh…
Thank you. Finally I found a picture that shows how these things work. Every single other picture I found shows only the front side of the Tuggnut.
