Chain Tensioner Am I asking for problems

[J-sizzles]

Am I just asking for problems if I mount the tensioner on the top of the chain like this? Remember this is my first attempt so don't rip me to bad I got a half link on the way and maybe a sexing wheel for the tensioner.

Dont cheap on your chain or your rear sprocket. Nice looking build you got going. 212 predator? That bike is begging for a 30 series torque convertor!!!

Good job with the fab work.

Putting the tensioner on the top side isn't the best idea because that's where the power is getting transferred. The bottom is where the chain doesn't have much torque, that's why it's always on the bottom.

Thank you. Yes 212. I'll probably do the torque converter on the next project.

Thank you. Is there a trick to get the arch tensioner straight? I've messed with it for a couple hour's already with washers and no washers. This is the setup that keeps the chainline the straightest so far.

Is the arch tension not parallel with the chain? If so twist the arch tensioner with a couple crescent wrenches, with it bolted to the bike in the location wanted. Probably take a couple 10" or 12" crescents.

Actually if you move the arch closer to your hub and put the tension pulley under the chain, the chain will clear the stay better.

Lol I know a easy way, buy a longer axle & spread the dropouts. Then use spacers on the axle. Chainlube might be correct on his suggestion.

So I got this now. My half link gets here Friday so I'll see how big a difference that makes. I put a internal geared hub on my mid drive e bike and blew through two cheap tensioners in a week, I put a half link on that with no tensioner and it's been awesome for over a hundred miles this week.

I think with a combinations of suggestions, like what Chainlube said, then add a 1/8" spacers on the axle to spread the dropouts a bit. Then use your crescents to put the twist in your arch tensioner to make it parallel with the chain.
