    I'M VERY PLEASED...

    Used for a 42/32/24 x 20 Drivetrain
    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.

    Works with 8 and 10 inch travel bikes
    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.

    PROS: Durable

    excellent for single speed
    this is a great for making any geared bike a single speed. it allows you to run an oval front chainring and switch rear cogs without adjusting the chain.

    Single Speed Conversion
    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.

    Solid product!!
    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.

    PROS: Lightweight, Durable, Enhances Pedaling Efficiency

    CONS: Difficult To Install

    How do I adjust this tensioner?
    Leanne D on Jun 9, 2017
    BEST ANSWER: Tension? You don't, but it's nice and strong and will last. Laterally? It has spacers included but may or may not get you to where you want.
