105/Ultegra hydraulic levers with Tiagra calipers?
Does anyone know if you could use 105/ultegra hydraulic 11 spd STIs with Tiagra (RS405) hydraulic calipers? Or are they not compatible for any reason? Cheers!

Hi, I have 105 shifters and Tiagra (rear) calipers on my bike.
Fitted by LBS about 18 months ago (remember the pandemic parts shortages?) and it works just fine
I've just checked my bike to make sure I wasn't imagining it.
Hope this helps.
That would make complete sense if they are the 4700 series BR-4770 calipers, it's the previous gen BR-RS405 that aren't according to the chart, which I think the OP was asking about.
It doesn't appear that they're officially compatible according to the chart.
Thanks for your reply and the chart, really helpful.
