Upgrading wheels---Will F&R derailleurs need adjustments?

Hey guys,

I'm upgrading my wheels from Mavic Ksyrium Elite S to 2016 Zipp 303 clinchers. I will be using the same cassette.
I will be running 25mm tires in the back, 23mm in the front. My Mavics had 25mm on both front and rear.

Thanks!

I upgraded my wheels from stock to a set of Pacenti and I had to do a little fine tuning on the rear derailleur. It was very minor and I did not need to adjust the front derailleur.

same here. I purchased a set of Vuelta SLR wheels (11 sp compatible) to replace/upgrade the stock Axis classics on my Specialized Secteur (9 sp ). Even with the spacer, I needed to re-tune my rear derailleur. It is unfortunate b/c I was hoping to be able to just swap them at will and use the old ones for use on the turbo trainer and the new ones on the road.

You'll absolutely want to check the rear derailleur adjustment after a wheel swap. If you don't, and the limit screws aren't set just right for the new wheel, you can dump the chain behind your cassette and do some serious damage.

Smart move asking here!

Now that you've asked, your new wheels probably won't require any adjustment.

If you hadn't asked and assumed the new wheels would be OK, your bike's indexing would be off by an annoying hair and you'd need a limit screw and cable tension adjustment.
