Max F Posted February 25, 2014 Report Share Posted February 25, 2014 (edited) I have a new Rohloff chain tensioner on my Inspired. Many people consider it as the best and strongest sprung tensioner you can get and I think it is. But even though the tension is that strong, the chain keeps hitting the frame, especially when putting the rear wheel back down after backwards nose manuals. And the noise and feeling of that is annoying me. I can easily push the chain down onto the frame with my hands and the sprung tensioner is moving just a very little bit upwards, so I think the spring could be as srong as it wants, as long as it bends just a little bit, the chain gets slack. Do I have to live with this? Edited February 25, 2014 by Max F Quote Link to comment Share on other sites More sharing options...

Max F Posted February 25, 2014 Author Report Share Posted February 25, 2014 (edited) It's already as short as possible. :/ If I'd take out another link, the tensioner would be bend more than recommended.

Ash-Kennard Posted February 25, 2014 Report Share Posted February 25, 2014 they really are strong, check out what it did to my mech hanger on 16:14 gear ratio! Quote Link to comment Share on other sites More sharing options...
Max F Posted February 25, 2014 Author Report Share Posted February 25, 2014 So you mean I should just shorten the chain to the minimum? Quote Link to comment Share on other sites More sharing options...
Ash-Kennard Posted February 25, 2014 Report Share Posted February 25, 2014 yes Quote Link to comment Share on other sites More sharing options...
J.KYDD Posted February 26, 2014 Report Share Posted February 26, 2014 Sprung tensioners will always still allow chain slap - not much anyone can do about that i'm afraid. I'd say your best off with a heatsink or custom spoke tensioner Quote Link to comment Share on other sites More sharing options...
Ross McArthur Posted February 26, 2014 Report Share Posted February 26, 2014 You dont get the high percentage of cog wrap with spoke tensioners like you do with a rohloff, so I always prefer to use a double wheel sprung tensioner. Do as Ash has suggested and also use a chain stay protector! You could always use more than one for extra dampning. Quote Link to comment Share on other sites More sharing options...
ogre Posted February 26, 2014 Report Share Posted February 26, 2014 if you have the right ratio and stay length, so you could run no tensioner, and just get a spoke to take out the remaining slack, that is in my eyes the ideal. if you can run a ratio like this then chain wrap (or lack of) shouldn't affect the performance. or just get your rohloff as close/tight as you can and use a chain stay protector.

Blake Posted February 26, 2014 Report Share Posted February 26, 2014 Ash's chain tensioner works pretty sick. Chainstay protectors make a difference too. Quote Link to comment Share on other sites More sharing options...
trialsalot Posted February 26, 2014 Report Share Posted February 26, 2014 Take that pin out that sits on the b adjustment notch and shorten the chain. Best tensioner there is in my opinion! Quote Link to comment Share on other sites More sharing options...
Max F Posted March 1, 2014 Author Report Share Posted March 1, 2014 Sorry that my answer comes that late. I actually just took one more link out of the chain. It doesn't even bother the tensioner, even tough the manual says I you shouldn't bend it that much. And it actually feels a lot better now, and only hits the frame (of course I have a chainstay protector on) really few times. If I'd remove that pin from the tensioner, it wouldn't work anymore, because the tensioner's arm would not lie against my frame. Works fine for me now. Maybe the chain will strech enough so I can take out another link. I can highly recommend the Rohloff tensioner. It's much better than the Trialtech one.
