Real quick,

Possibly replacing chainrings on my bike and the ones I'm looking at to replace them with will be a tooth smaller on the big ring, going from a 53t (current) to a 52t (replacement).

When I sized my current chain, I did the whole 'big-big-not-routed-through-derailleur-one-full-link-overlap' with the 53t that's on my bike. If I drop one tooth down to a 52t, is it worth it to take a link out of my chain? Or just leave it alone? Right now it's about perfect in length, not killing my derailleur on the big cog, and my derailleur is still taking up slack in the small cog (there's still spring pressure on the chain).

I'm assuming that one tooth shouldn't hurt and I'd be fine to leave it alone.

Thanks! You guys are the best.
