    Tensioner Reliable?

    With more and more manufacturers dropping (or never had) their high end frames in single speed versions, along with keeping the bike shop I ride for happy, I was wondering how reliable a tensioner is everyday use. I run single speed exclusively for mountain biking and race the NUE series so I need something that is as reliable as say paragon or EBB tensioning system

    My DMR Simple Tension Seeker works great. I've been using it for 2 weeks and haven't had to adjust it yet. No springs or anything so it doesn't jockey around when the trail gets rough.

    I've never had a problem with tensioners.

    I've run an old derailleur, which worked great but was heavy. Then a rigged up Vbrake, which worked great for awhile, but the spring started popping off the post over rough ground or when jumping. Now I have an Alfine tensioner which works great, but is only about 80g less than the old derailleur.

    EBB work, but make noise over time. I prefer the sliders.

    Thats great...did you even read the post? Read it again. I'm asking about running tensioners on a non SS frame. Ie no sliders, no EBB.

    I had someone tell me that a decent quality tensioner properly installed is every bit as reliable as a derailleur. That argument made sense to me.
    Mind your own religion.

    My apologies. I was a little distracted when I posted.

    But my response is that the EBB is noisy over time. Therefore not reliable as you put it.

    A tensioner will work fine. I've installed this one on a customers frame.

    fwiw... OP didn't say an ebb was reliable. he said he was looking for something as reliable as an ebb tensioning system.

    Tensioners work. So does a WI ENO hub. Another option maybe?

    Not an option for me. I run a powertap 90% of the time, and have a set of carbon race wheels.

    Fair enough. You could also try a Blackspire Stinger (BB mounted chain guide) to take up the chain slack and give sufficient tension. Have seen it used a few times to great effect. And does not ruin the aesthetics of a SS.

    Was referring to the WI eccentric rear hub. No tensioner needed.

    Yes, good tensioners work great, and there are several excellent options to choose from. Off the top of my head:
    - White Eno hub
    - Rennen Rollenlager
    - DMR STS
    - Yess ETR B
    - Phil Wood Philcentric

    Any of those will work very well, with the real differences being in looks and ease of use. In my opinion, the tensioners tend to work better than a single speed frame, and you're also not locking yourself into SS with the frame.

    Aside from the Yess ETR B, avoid tensioners which rely on a spring to maintain chain tension.

    Rennen rensioner and Blackspire Stinger chain guide have already been mentioned. I have one of each and they are reliable.

    Tensioners at the rear may be in the way when removing the wheel. Chain guides at the front may require some care when removing cranks.

    So with the Blackspire Stinger, do you take the roller off to change a flat?

    No.

    No need for anything special when removing the wheel, using a Stinger. Unless you have horizontal dropouts and still want a Stinger.... Just loosen the wheel QR or bolts and the wheel comes off.

    When removing cranks, things can be pretty tight between chainring, chain and the roller, especially if you have the roller very close to the chainring, as I do. Then you need either some chain slack (remove wheel), or the roller further away from the chainring.

    I tried a Stinger I got used for five bucks. It didn't take up quite enough slack (and the chain wasn't long enough to remove another link). Back to the Alfine tensioner.

    You could always use a half-link. That should enable you to use the Stinger. If you want to, that is.

    For sure, try a half link. Just search "gusset slink half link" on this site before you commit. Read up on the various approaches that have been tried. Half-links can be tricky.
