We have just finished putting the final touches to this sweet S-Works Roubaix custom build. Featuring the latest SL4 Fact 11m frame, a Shimano Ultegra Di2 group set and Easton wheels/stem. Check it out!
Matte black and awesome.
The black/white/red rims of the Easton EA70 wheels really work well with the frame.
The grey colour of the Ultegra drive chain also works well with the matte frame.
