  • I fitted a 'weaponized' brand (oblig. no, YOU'RE a weapon...) singlespeed tensioner Tuesday night and Wednesday's commute was much faster because I was able to change the 18t sprocket for a 16t one. Yay!
    Except today the chain started slipping in the wet. Boo!
    Because this was an emergency single speed conversion (my usual hi-ten beater is up on blocks) I have a feeling I slapped a 7/8 speed chain on there. Given the cog and chainring are supposed to be for a 3/32 setup - is that likely to be the problem?
    Or is my chainline the issue?
    Also, the tensioner seems to add a lot of noise to the whole transmission. So maybe I am answering my own question re. chain and chainline.
    Just thought I'd ask here anyway! TIA...

  • Does it tension by pulling the chain out or in? How much chain wrap do you have around the sprocket? Where does the chain come off? What do you mean "slipping"?

  • The tensioner pulls the chain out and so there's noticeably fewer links about the sprocket - I've lost maybe third of wrappage, I think. Slipping is a sharp 'snap' sound when I stand on the pedals to push off with my mighty nay awesome powers

    I think I'm going to look at setting the tensioner to push the chain in (remove the spring) and fix it in place. And make sure my chainline is straight as. I tend to do things by eye and well... [marty_feldman.gif].
