Single Chain ring and chain length

I went to a single front chain ring and read that I now need to take out some links but I am not sure how to tell what the proper length should be.
Any help

Same chain sizing recommendations as always. Loop chain around big-big, bypass the rear derailer, join chain at the next longer opportunity.

Loop the chain over the ring and largest cog.
Make sure you have at least one linkset, but not more than 2.

IF your single ring is no larger/smaller than the rings you had, you really don't need to do anything though.

The suggestions above are for the shortest chain possible. Many derailleurs wok better with some more chain that that.

Campagnolo recommends the longest chain possible, measured with the chain threaded through the RD and on he small sprocket and pulled up the RD takes up th slack in the lower loop. Shimano recommends something in between.

I prefer running chains to the long side, and so use the Campagnolo method, but sometimes take an extra inch or two off that.

In any case, ALWAYS double check the shortest length method, because accidentally cutting a chian too short can destroy a drive train.

+1 FB, I've been using the longer chain method for over 40yrs. I'm 220lbs. And never had a problem, I continue it on customers bikes as well. One thing for sure, if they ever shift big-big they will still have intact derailleurs and spokes!!!
