Some advise needed please...

I have a LBS Demo Roubaix for the weekend to try out. Find it really comfy to ride, did 20mls on it this morning, 13 on Friday. This mornings ride was tiring as not done 20mls for a while, so a few aches and pains in the latter part of the ride, but overall no issues with my back, so all good.

One issue with the bike is the Sora groupset, do not find it as smooth as I was advised, I was told this groupset was the 105 a few years back and should run nicely.

Upgrade to next Roubaix is £1600 which is a lot more than the deal of £1150 for entry Roubaix.

I need the comfy ride as of my lower back, shall I put up with this and upgrade in 6 months, I already know I will need to upgrade the wheels in the same time.

What would you guys suggest?
