YEES makes really good tensioners for
many different set ups, rode one for two
seasons no problem. The chain needs to be tight or it will skip every once and a while
That stuff has been around for a little while, people who have ridden it say it's good like it doesn't squirm around
under your wheels. It could really help if you have bad soil, heavy traffic , freeze thaw etc. would be awsome
on a dirt pump track.
