Just preordered my Kilo (really happy about this) and am wondering what chain tensioners everyone (that uses them) uses. When i had a Bianchi Fremont, i had MKS tensioners for it and thought they were nice, but am wondering what else is out there. I know Surly makes the Tugnut[?] but don't know of any other ones, what are good ones to protect the frame/dropouts as well as keep good tension? Thanks
