I have to choose between tow 2nd hand SL4 frames... and the price difference is almost twice. I can't believe this. I think it's all about marketing. But maybe I'm wrong.

Thank for your advise

I did an analysis of the 2021 Tarmac SL 7 Sworks vs the Tarmac SL 7 Pro. If you were to replace the Rapide CL wheels with the CLX the Pro equipped with Ultegra DI 2 only weighs about 3 oz more than the Sworks equipped with Sram Red. So you get the performance advantage of the CLX wheels which is where you get the biggest bang for the buck for about $8k and a very almost insignificant difference in weight. As I understand the only real difference in the frames is the weight (120 g) the aerodynamics, geometry and the stiffness is the same. Later down the line you can replace the Ultegra cassette with a Durace(wait for a sale) to further reduce the weight not that you need to.So unless you want to insist on impressing your peeps at the coffee shop with the Sworks label save your $4k and spend it on a cycling vacation somewhere. Also the Pro comes in a gorgeous deep red .
