Should I shorten chain?
Road bike on cervelo

when i shift to smaller ring in front
and go to more of a climbing gear and sway bike,
my chain is rubbing on the spokes abit and seems loose
should i trim chain a link or 2 down? thanks

Size it by one of the several methods and you won't have to guess.

Put it on Big:Big and see how much slack you have.
You want at least 1" + fraction of a link SET.

The big/big test is done with the chain NOT running through the rear derailleur. Bring the ends together and add 1 inch, to get the shortest possible chain.
Another test is to shift to the small chain ring and smallest sprocket. In this combination, the chain should have a little tension on it and not hang loose, assuming you're not using a largest sprocket that exceeds the RD's wrap capacity. In that case, the chain may hang loose in 2-3 of the smallest sprockets, when in the small chain ring.

My test can quickly be done in situ and give a VERY good idea if you are too long.
It's even simpler if you're not holding a camera in the other hand.

Of course, and any of the methods will account for that.

Sounds more like a derailleur adjustment. The only place the chain gets near the spokes is at the derailleur.
On the stand shift into the lowest gear and give the derailleur a push towards the spoke and see if it rubs.
Bent hanger or limit screw if it does.
