Its a tough market to be in right now. At ~500USD for the hydro group its tough to justify going with an unproven product when you can piece together a Sram AXS rival 2x system for less than $600 including batteries and an Apex 1x lever set w/ Force brakes + Rival Xplr RD for $470 including battery.
The Wheeltop system also loses the removable battery which is a really nice part of living with the Sram system and you also lose the clutched RD.
Edit: should add that its $522+tax RN to grab open box 105 di2 levers+brakes, FD, RD, battery and cables from the Pros Closet; so there is another option in that $500 price range for electronic shifting for the US based people.
