Have an old ultegra 6700 3×10. Looking to upgrade, is this everything I’d need if I were to keep my rim brakes? It comes out to about 450 euro, does it make sense?
although these days, i’m not sure i would drop 450 euros on a 105 mechanical drivetrain (without brakes and with the shitty RS510 cranks…). i wouldn’t pay more than 200 for all of this

If I were you I would look for the best price for single parts and buy them from different shops. What I usually do is looking for people that bought new bikes and replaced the groupset before riding it, those are usually cheap.

It’s probably easier to find a 2nd hand bike that has 11s 105 for 450€, transfer the gear to your bike, move the 6703 over to the other one and sell it.
I’ve recently bought these exact same components for a new build and I did get them for way cheaper;
– Shifters and derailleurs: Aliexpress 175€
– Crankset: Bikediscount 45€
I had lots of cassettes and chains lying around.

Those are all the correct pieces to go together, but why?
That’s a lot to spend to save a few grams in weight. Unless the drivetrain is badly worn out, and most of that needs to be replaced anyway, I don’t see the benefit.
If you are going that far, I would probably put a new bottom bracket in as well. You’re pulling the crank set on an older drivetrain, makes sense to me to put a fresh bottom bracket as well.

Are your wheels 11 speed compatible?

You don’t have modern shimano dropbar levers that work 3x, except claris. But it doesn’t do 10x, it does 3×9. Chain on 9 and 10 are compatible. Your ultegra and that claris are kinda same, in tech way, shimano trickled down that tech into lower end over time.

I would just get an inexpensive Chinese shifter. All of them actually work pretty good.

yes, everything should be compatible.
