    Weak tension on Surly Singleator

    I've had a Singleator for a few years and replaced the spring once or twice. I had a couple chain drops so replaced the spring again, but tension seems pretty weak. I made sure to to loosen the hex bolt, while putting tension on the spring. I may have overtightened the spring initially, but tried it a couple times and something still seems off.

    Any recommendations? I may take the full thing apart, clean it, re-grease it and try it again.

    recommendation: get rid of the Singleator. I had one and it generally sucked. If I did not have a SS-able frame, i would be running a DMR tensioner or, even better, a Blackspire Stinger.

    Yeah, but still no luck. The chain isn't dropping but it's quite loose.

    Thanks for the recommendations. I'll probably give one of those a shot

    I'm running a Singulator in push up mode and a DMR STS in push down mode.
    Both work nicely.

    The chain is slightly stretched so I'll probably replace it when I get the new tensioner. The chainring and cog seem good. Not sure how much that would affect the tension strength tho?

    Zip tie it, but don't overtighten it. Watch the tensioner move up and down as you turn the cranks-you want to maintain that freedom of movement, or the pulley will be fixed against the chain, putting stress on the pulley and creating both noise and noticeable drag on the chain.
    You're not holding it in place, just limiting its travel, which its spring isn't strong enough to do on its own.
    Not at home, so I can't post a pic, but I use two zip ties. One loops around the arm the pulley is on with just enough clearance for the other zip tie, which goes through it, and over the chainstay. It's less noticeable than looping a tie around the tensioner itself, like I've seen many pictures of. May not make any real difference, but I like that it's pulling straight up on the pulley arm rather than putting pressure on it from the side.

    Mine is just like that, except I made the bottom loop very small-same thing.
    Yours work ok?

    i am running the Singulator for almost 2 years, and every several months need to take it apart and re assemble it, last month it started to mis-behave, had a chain drop every ride... so this morning i zip tied it seems to work well so far (1 ride) will see how it goes

    I've had 2 Singleators. I think they suck. Had good luck with a Gusset Bachelor.
