    Comments about Shimano Alfine CT-S500 Chain Tensioner:

    I installed this on my old race bike. I converted it from a 1x11 to a singlespeed. I now have a fully suspended single speed. This tensioner does exactly what it supposed to do. It's a little heavy, but does the job and then some. I just purchased another to put on my wife's bike!!

    Single Speed Conversion

    By Dave

    from Orange, Ca

    About Me Commuter

    Comments about Shimano Alfine CT-S500 Chain Tensioner:

    I converted my MTN bike to a single speed commuter/around campus bike. Very happy with look, install, price, and quality of this product.

    I am running a 32 front and 13 tooth rear with 26in wheels. I plan to put a large front gear.

      Comments about Shimano Alfine CT-S500 Chain Tensioner:

      Have been using this tensioner on my 2009 Yeti 303R DH for two and a half seasons (75-100 park days) without a single issue.
      My father has been running this tensioner on a 2009 Santa Cruz V10 for one and a half seasons without a single issue (30-50 park days).
      We both did need to purchase a bolt and nut assembly to prevent the tensioner from wrecking our derailleur hangers, but it hasn't needed another look since being set up like this.
      Yesterday I watched my friend take my bike, ride over a metal skinny, flip the rear tire off and loudly bang my tensioner on the metal rail. The tensioner was unfased.

      Comments about Shimano Alfine CT-S500 Chain Tensioner:

      I use the tensioner on a road bike I converted to a single speed. The tensioner runs very smoothly making only a little bit of noise. I had it installed at my LBS but it was very easy for them to set up the tensioner for a straight chain line.

      Used for a 42/32/24 x 20 Drivetrain

      By PB Matrix

      Comments about Shimano Alfine CT-S500 Chain Tensioner:

      Love this product made by Shimano. The spring is strong. Works with any chain type. Works better than the 3 x more expensive Yess model that does the same thing. Uses shims to set up chainline and this might take two or three trys to get right.
