Considering the amazing off-season sales that went on this spring one could think the golden age of buying cheap chinese carbon direct is long gone. To an extend the notion is true. Players like PlanetX and Canyon did offer great deals this spring. It is very difficult to beat an offer of a complete carbon bike with SRAM Force groupset for 1200€ considering you get a full warranty and support. What you can’t get buying a ready-made bike is the full custom experience.
There is something strangely satisfying in building up a bike yourself. Sometimes you can also recycle parts from an old steed. The second hand market for bike parts works great on the internet. For example if you are willing to stick to 10-speed drive train for few more years there are some excellent bargains to be found. The real question is what the next big thing (electronic shifting, power meter or something else) is you can not ride a bike without and when can you source direct?
