2016 Specialized Roubaix SL4 disc rotor size?
Hi
I purchased a 2016 Specialized Roubaix SL4 disc frameset and am in the process of building it up for summer. I can't seem to locate the specifications for the front rotor size. Is it 140mm or 160mm? Is some sort of spacer required for the post mount caliper? Some of the pictures I've come across seem to show an aluminum spacer between the caliper itself and the fork mounts.
Thanks!

Don't know about that specific model, but the spacers are usually to match the disc size you're using. My fork for example is for 140mm discs (no spacers required). If you use 160mm, you use a +20 spacer, etc.
A few google searches seem to point to 160mm in the front ant 140 in the back for the Roubaix.

Normally, when you buy a disc set, it comes with the adapter you need.
