Without derailing this thread, how do you like the Switch frame? Any actual weights? I've seen 'em for sale on ebay occasionally and am really intrigued.

As for the brakes/stem combo, I say no. That frame deserves ****** parts, but you don't need things like internal DI2 and cable routing for your SS. Plus thats what, $520 on a stem and brakes? I think your money could be better spent pimping your ride elsewhere.

At ~250g/pr the brakes are 45g lighter than DA or Campy but ~50g heavier than a similarly-priced brake from KCNC or Far & Near. The stem is ~115g heavier than an $80 3T Team.
