The whole SPA thing looks more like a marketing stunt from Trek without real use in P-R, at least not by the podium finisher by Hincapie. Look at the bike Hincapie rode in last years P-R, it had no SPA, but was just a normal Trek and it wasn't a spare bike because it has his race number plate on the frame. There's no number plates on the spare bikes.

After the race Hincpapie's normal Trek was swapped with the "P-R edition" with SPA, so he could walk with this bike to the podium and journalist could take pictures of this special "Paris-Roubaix" bike as if Hincapie actaully rode it in the race and write an article about Trek. The bike Hincapie swapped to for the walk to the podium ha SPA and was even covered with mud and all to make it look authentic, and now with two bidons instead of just one as shown in the sprint above and also without his race number plate which was on the race bike which was just a normal Trek without SPA.
