Which Groupset?

I think I've spent too much time looking at Dammit and SmallFurry's builds - I looked at the relative weights of groupsets today - Ultegra is almost 350g heavier than Force.

Have worked out that I get 100g grams of that back by keeping my S-Works carbon cranks and can save another 130g back by using PX cnc'd callipers with Swiss Stops instead of the Ultegra ones.

Much as it pleases me that you have taken this step onto the darkside. I've heard nothing good about those PX calipers.
