From a reputable Western brand canyon Aeroad CF SLX 7 eTap (Rival AXS) at $4500 and $5300 (Sale ended back to $6K) for the SLX 8 eTap (Force) before shipping and tax, which are both insane deals because full integrated carbon cockpits, carbon wheels, and powermeters included

There is also Quintana Roo SR5 105 Di2 is $4600 before shipping and tax, Integrated aluminum stem and aluminum wheels

If you are okay with the idea of building a bike then just getting a frame set like the Tarmac SL 7 $3300 and then doing a cheaper Rival AXS build w/ some $1K carbon wheels would be around $6K.

I built a Winspace T1500 Disc w/ Rivals AXS and Hunt Wheels for under $4500 all in.
