    Chain Tension

    In the mechanics section I saw the talk about chain tensioners, which is something I am interested in for my LWB since the chain has a tendency to "bounce" off the rear sprocket (7 speed nexus hub, not cassette) on rough paths. They had this link http://www.kore-usa.com to Kore's chain tensioner (select the Drive option from the menu). Any one ever use anything like this to keep their chain in check on a 'Bent? Since the chain run is longer I was just wondering if it work on a 'Bent as well?

    i'm not too famililar with recumbents and what you have set-up but if you need some kind of retention a must visit site is www.dhrings.com, its an ColinAub Precision Components site that specializes in chain retention systems for downhill bikes and i know that they have made some custom systems for recumbent mfg'ers, check'em out, you may need to call them - Randy

    Seems my problem is the long chain run between the crank and hub. I have a nexus 7 speed hub rather than a cluster, and when going over rough (usually dirt path with ruts from when it was muddy) the chain will hop from the top of the rear sprocket when I cease pedaling (putting pressure on the chain). Would something like the KORE chain tensioner mounted upside down and putting pressure on the top run of chain cause any other problems like with the front derailer and shifting, etc.
