How can I change components on my bike?

I honestly still do not know what your real problem is, as sora are made for drop bars.

Perhaps if you described your issue, there might be some more input?

Unless you have really long thumbs, you can't upshift the cassette from the drops on a bike with Sora shifters. You have to bring your right hand up onto the hood to make the shift. The left hand is less of a problem because you're downshifting with the thumb lever, and less likely to be in the drops.
