DMR Simple Tension Seeker: SS Chain too wide for pulley
myopic
Posts: 692
As part of SS build, I bought the SS conversion kit from DMR which includes the Simple Tension Seeker. Also bought a SS chain.
After fitting, found the drive train was running very noisily and lumpily and this seemed to be associated with the tensioner. Checked DMR website and found that this device is primarily for use with multispeed rather than single speed chains. So it looks like the problem is that the chain is just a bit to wide for the groove in the nylon pulley wheel and tha'ts why it's not running great.
Options are:
(a) run with it, put up with noise and hope that with wear on the shoulders of the pulley wheel the fit will improve
(b) trim the groove in the wheel to take the wider chain - don't have a lathe though, so would need suggestion for best way to do this!
(c) any other ideas?[/list]

Had the same problem with an on one tensioner. Played around with the setup until the noise only happened when backpedalling. After that I stopped backpedalling! It's done a while now and seems alright.Rock Lobster 853, Trek 1200 and a very old, tired and loved Apollo Javelin.0

I have the same issue, I just go along with it really, doesn't appear to do any harm and you don't notice it among all the road noise. Just make sure you have the chainline set up as straight as possible.0

get a tensioner that works with your chain/change the wheel."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

Well I solved it by using a stanley knife to shave a small amount off one of the inner side surfaces to make the groove wider. Runs sweet and totally silent now! Thanks for the replies.You don't need eyes to see, you need vision0
