I know most of you think they are gay. The fact is my chain keeps coming loose on my lemond. It takes a few days but it will be loose and I'll need to re-tighten. Do any of you use a chain tensioner like the MKS one or perhaps one of the many BMX ones that are cheaper (such as the redline one http://cgi.ebay.com/REDLINE-Alloy-Ch...QQcmdZViewItem )? Do they fit any track end? Or...Can I simply get better tracknuts as a solution? Thanks.
