The Lynsky doesn’t look like its setup to do 11 spd. Di2 electronic, in terms of frame holes to install shifter cable in the downtube. You would have to do wireless shifters, Di2 105 or Ultegra, or SRAM AXS. With Di2 that means 12 speed. States it has rear thru axle, you would need to get a separate fork. Cant tell what the rear disc brake mount is. It’s a good price for the frame, but by the time you source an electronic group set, plus wheels, plus bar, post, seat, tires, stem, etc…. Might not be that cheap. Also look at a Habenaro, the current road titanium, setup as 11 spd. Ultegra Di2, with a Ritchey fork, is about $4300.
But I agree that titanium is the most future proof in theory.
