  • Weak spring
Color: silver
It’s spring was weak and deformed.

  • Good for what it's worth but has minor issues
Color: silver
Due to the design the swing arm has a tendency to loosen the bolt and nut that hold it in place as it swings up and down. Highly recommend having tools on hand and making pit stops after excessive bumps to check that the swing arm of the tensioner is still level and tight enough to function properly. Otherwise has been doing its job perfectly and keeping my chain on my sprocket and preventing binding inside the case. ... show more

  • The best one to get
Color: silver
I’ve tried countless different spring tensioners. Many didn’t work from lack of adjustability. This one’s PERFECT!! I’m using a 32T sprocket and it tensions perfect.
