Re: how much better is this?
I had to use the chain tensioner, just cause of chainstay clearance. Its a tight fit even though I spread the frame. I didn't drill, but I agree that I need to find a better solution. Probably welding something permanent.
But I did one thing that I'd recommend to anyone when they first start out with the build. At the very least swap the two tensioner bolts and nuts for grade 8 stuff from home depot and tighten the hec out of it. Then check it to make sure its solid before every run. Never trust the stock hardware, it will strip, it will loosen and you can't tighten it enough. I would guess with folks' first build they just try everything stock. I don't think they should be shipping with such low grade tensioner hardware. I think thats the deal breaker right out of the box. Until a better tensioner ships with the kits, I'm afraid many folks will install the thing as is.
