How-To/Mechanics: chain too short or too long

I did some searching but couldn't find exactly what I was searching for. So basically when I take out a link its either too short like the pictures. Then when I put in a link it becomes too long and the bolt is almost hanging off the ends. The tension is really really tight when it's at the closest setting & seems very dangerous. I'm not too sure what would be the best thing to do..oh and I'm running 46x17.

Yea a half link would do the trick. I think that might be your only option without changing your gearing. I could be mistaken. Anyone know anything I don't?

Personally, I would ride it as far up close as possible, as long as the tire does not rub.

you are right, those marks are from the other attempt. here's how it actually looks.. not sure if I can call that full contact, probably 4/5 is though. I wanted to run it up close too but that 1mm-ish play doesn't seem too safe. I'm gonna run it far back for now because it's probably gonna slide forward after riding. seems like all that tension would probably break my chain tensioners too.

Your wheel is not going to slowly slide forward. Actually the opposite. After a few months riding, your chain will start to stretch and you will find you pulling your wheel back about 1/4". Maybe at that time, take out that extra and ride your wheel closer. It's better the closer up it is.
