I'm working on a singlespeed conversion project right now with a cannondale touring bike circa '85. I am very limited on wheel options due to the 126mm rear wheel spacing (frankly I would rather not buy new wheels as I'm trying to keep it budget anyway) I put on a freewheel, which then gave me an awful chain line. I then installed a narrower bb, to bring the outer ring in. After finally fixing my chain line, I have found out that the tensioner I was planing on using will not work because it pulls the chain outward (away from bike) (gusset, similar to rennen i believe). The bike has diagonal (basically vertical) drop outs. I'm currently using a sram PC1 chain. I'm going to try to use a half link, but I don't think that will get it quite snug enough. Anyways, I was hoping to find out some alternate methods of chain tension adjustment if there even are any. How do the non-horizontal drop out guys get good chain tension?

I have 2 salsa chain rings (53t and 38t) that I would love to exchange for parts or service contributing to the completion of my bike. I am located in the bay area.

since nobody bothered to answer my post, I will answer it myself in case someone looks up this thread for their own research.

I put on a half link, which then allowed me to set the wheel fully in the dropouts, with too much chain slack. At this point I loaded up the dremel with the aluminum cutting/grinding barrel and went to town. I would suggest this technique to anyone with an aluminum frame, and enough drop out room to cut away up to 5mm.

wait, what did you do with your dremel? Did you try to extend your dropouts?

There is something called, chain-tensioners.

You shouldn't be drilling frames whether it is tampered steel or aluminum.
