Heads up, singlespeeders! If youre trying to convert any recent model bike into a singlespeed, youve probably realized by now that since the dropouts are vertical, there isnt any way to properly tension the chain. Surly comes to the rescue with the Singleator. This handy device mounts to the derailleur hanger and provides proper chain tension in a simple, lightweight package.

  • Tensioner allows use of 1-speed drivetrain on vertical drop frame
  • Mounts to derailleur hanger, self aligning floating pulley
  • Adjustable chain line
  • anti-chain drop hoop
  • This part requires an 18mm Cone wrench to make it work. See the the Surly wrench below. Its the perfect fit. If you are self-installing, make sure to have one on hand. Make sure to read the instructions.

I used this component on a single speed road bike conversion. It was easy to install (I set it up to tension the chain upwards, using the supplied spring.) I used it with the Gusset single speed conversion kit...I was a little worried about the chain line, but it set up perfectly. I've been surprised at how little tension it takes for proper operation. It's quiet, and I haven't experienced any problems with the chain skipping on the cog. That may be a mountain bike only problem. All in all, a great product.

I got one of these to convert my bike to a single speed. I ended up selling it on ebay because I couldn't get my chain to stop skipping. It's because of the chain wrap around the rear sprocket. It needs to be in the "pushup" set up in order for it to not skip. I didn't want to fool with it anymore. I put my shimano Deore XT rear derailler on in place of it ,adjusted the adjustment screws in acording to the chain line and It works just the way I wanted it to.

    Surly singulator AWESOME!!!!!!

    By gtalaa

    Comments about Surly Singleator Chain Tensioner:

    I reversed the spring for the singulator to be pushing up on the chain and it works flawlessly. I've been using a standard tensioner most others have been using for years and it skips teeth and bouces around on decents. This one is dead quiet and never skips teeth even on the most grueling climbs (32x18 gearing). I like how the spring is internal and the unit is very nice looking. With the way I'm running this unit, it is almost unnoticable on the bike as it runs close the the bottom triangle rail. I love this thing.

    Comments about Surly Singleator Chain Tensioner:

    You absolutely DO NOT need their overpriced bottle opener, the action of your Hex wrench sticks it to the frame and it's the *position* that makes tension...I really have no idea what that wrench is for.

    It's fussy to install and it performs poorly. They obviously cut corners on it's design and did not test it thoroughly.

    awesome if serious about converting to SS buy it worth the coin, spring up or down both work well chain stays where it needs to be, and im riding full rigid so it rough going, just be sure to get a straight chain line

    Comments about Surly Singleator Chain Tensioner:

    Did not perform well at all, chain kept popping off every time I was on a slight rocky area. the tension just could not hold and after a while I would have to readjust it for more tension on the chain.

    Comments about Surly Singleator Chain Tensioner:

    I have used this product in Light DH and medium jumps and doubles and really works fine, it keeps the chain in place and works as expected. Good stuff and using a Single Speed is better and simple.

    Comments about Surly Singleator Chain Tensioner:

    Overall, this is a better deal than a DMR tension seeker 2. It has less parts to deal with. You need an 18mm cone wrench to install, but the Pedro's wrench I bought with this product was too big to fit in the area it needed to go in to. Skip the tensioning mechanism and use a zip tie.
