    Swaping chain rings, shorten chain?

    I'm dropping my 40t to a 36t on my DH bike. Anyone know if I should drop a couple of links off the chain or should I be fine with the length that worked with the 40t?

    As a rough rule of thumb I leave just enough chain so that I can shift into the big chainring and the big sprocket on the cassette.

    I would say that if you were going from a 40 to a 38 it shouldn't be a big deal but since it's a bit more I'd use the big ring to big cog method as already stated. You should be fine either way.

    Did you keep the 22/32/bash set up or did you change out the middle ring? I'm running a 22/36/bash set up and really like it. I still have a pretty decent top end and I seem to ride just a little bit faster with the 36 and any combo in the back. I also feel better ramming into things and not having to worry about breaking teeth off of a big ring.

    haven't changed out the middle ring, Might try changing them but I leave it in the middle ring so much nowadays that it might put me back into the granny more often if I swap it.

    You'd be surprised that it just makes you a bit stonger. Maybe start with a 34 tooth and see how it goes.

    Technically, for ever 3 teeth you remove from the biggest ring you can remove one chain link.

    Hey man thanks again for the link, that largest cog to largest chainring method worked like a charm.
