I have upgraded a bike from 7 speed 105 to 8 speed Claris. I changed the wheelset and shifters, but left everything else alone. Worked pretty decently, considering the age gap between the old derailleurs and new shifters. I think Claris shifters would be worth a try, at least. One thing to bear in mind though is how much heavier STIs are than downtube/barends. I really do like the convenience of STI myself though, compared to downtube.

I also had this issue.

But i havent used STIs and this is a perfect time since i have no onterest in changing any of the other bikes.
Well that makes sense to me.
