Microshift makes shifters and derailleurs. We package it into a complete groupset with parts from other makers. If we gave the groupset the name of all the manufacturers of each part.... it will be a really long name, which is why we name it SOUL/ Microshift instead. I'm not familiar with Sun Race's offering.

There are no ceramics in this groupset. but you can upgrade the bearings in the pulleys and BB to ceramics. Not sure why you would but that would be a whole separate debate.

The picture is my personal bike, I try very hard not to post things up that can be deemed as free and blatant self promotion, but ti frames are getting rare nowadays and I'm just trying to keep the interest going as it is a fantastic material for a bicycle frame.
