well, here you go...chain tensioners. again, i'll start with the one i have, and just keep this going. maybe add a little review since there aren't too many.
Rennen Rollenlager:
best, and only tensioner, i would consider using...hence the reason i bought it. strong, and not too heavy. the guys at Rennen are pretty cool, as well. i recently was made aware of one issue, though, and that is with breezer dropouts. the roller is nice and quiet, and rolls on cartridge bearings.
