    Help with chain slack

    I've browsed several "post em" threads here and everyone seems to get along without a tensioner, even vertical dropouts. I saw only one bike here in all my searches with a tensioner installed. I have a tensioner on this bike now, what am I missing, here? I'd love to do without.

    Take a link out? Half-link?

    One link is too much, but I just researched half links. Don't know much about them. I guess that's my only option here.

    But the tensioner works fine. Just not as clean lookin.

    Figure out the length of your chainstays and find the magic gear

    They may have EBB's that you cannot see.
    Something wrong with your bike? Blame it on super human strength and sleep well at night knowing you are more than a man.

    That MRP doohicky is not a tensioner, it's a guide. You need a chain tensioner like a Surly Singleator that mounts where the derailleur used to be (there are other types, but this style is the most common). Take that MRP guide off - it is useless on a single speed and is meant for bikes with a rear derailleur and no front derailleur.

    You need to compute your magic gear. You will need to measure your chainstay length, then enter it into the FixMeUp applet:

    You will need the Java runtime installed to run this.

    This - didn't even think about that. If you think the MRP thing is a tensioner it isn't. You either need the magic gear, a tensioner or use an old deraileur.

    Much of that is because people are purists and will do ANYTHING to avoid using something that LOOKS like it is tensioning the chain.

    Here's my tensioner, AKA Blackspire Stinger. My other bike has a Rennen tensioner in the rear. I will not touch spring loaded tensioners, unless I go crazy and get a singlespeed FS bike.
