I only have about 4mm clearance from my chainring to chainstay. Should I be worried?

Well, I think the title says it all. I only have about 4mm clearance (give or take .5mm) from my chainring to chainstay. Should I be worried?

Unless your frame is really flexy I wouldn't worry about it.

I switched from a 53 to a 49t chainring when I moved the ring from the outer to the inner position on my cranks. the 53 was pretty big (gear-wise) anyways and just touched the stay. Now the 49 probably gives me 3 or 4 mm of room. And all is well

It'll probably be fine. The worst that could happen is that you'll see paint start to rub off a bit from frame flex, at which point you will probably want to get a smaller ring. 4mm is acres of room though, it shouldnt be a problem.

My 51t ring is so close to the stays that it'd be impossible to slide a sheet of quality paper in between the two. It really depends on the frame and amount of flex the set-up has. My frame is aluminum and has zero flex...my cranks don't flex enough either. On my Casati, the set-up I run now would have ground away metal from something. Mash as hard as you can on the pedals...if nothing rubs you're fine.

What is your frame size, chainring, and crank model/size? I'm curious because I just put 165mm sugino 75s on my 62mm Angus, and there's like 3mm space between the crank and chainstays...and about the same amount of space between the 46T chainring and CS.

I call bull****. On several statements, the first of which being the assertion that you have less than 0.1mm clearance, the second that you have no frame flex.
