Obviously I know that. You have completely missed the point. S-works frame is available for around £2600 (discounted) my whole bike cost less than that. The weight difference for dura ace over ultegra is marginal & it performs no better. Extra stiffness of frame is a marginal benefit if any for recreational riders, even relatively fit ones. I made a decision a while ago to ride a relatively modest bike & given a recent hip injury that choice has saved me a lot of money. I do find the sight of older unfit men on £6k bikes rather unedifying. Having said that my mate is going a fair bit better than me at the moment.The extra cost goes into a higher grade of carbon and a different weave to produce a stiffer frame, plus upgraded components like Ultegra to Durace etc.
