Seems like no one agrees on what exactly to call them. But I'm looking for a chain tug designed for a track end. The Surly chain tensioner looks like it might be a little to fancy for my bike, and the Primo tugs that I've seen are pretty bulky. My goal is to find something relatively low-profile that won't add another pound (exaggerating, of course) to my bike.

Anyone have any recommendations?

By the way, I just joined. This is by far the best bike forum that I've visited.
