Thanks for the responses!

Yes I do believe Claris is new. It replaced the 2300 group from what I read. I will probably hold off and ride what I have until it starts to fail then look into upgrading. I do shift quite a bit and try to keep a steady cadence so having more gears was what I was looking for. Shifting and braking feels fine to me. It is slow on a few gears but that is more than likely just an adjustment issue.

What is the benefit of upgrading the cables?
