I just received my set today so I have these in hand and not via a sales rep.

If my digital food scale (zeroed) is corrrect, here is the weight info I recorded for the Ultegra Tandem set:

2012 Ultegra Tandem set:
R601 - Captains cranks (175mm) incl timing: 665gm
1- BB6700 (bottom bracket included in the set) : 95gm

R603 - Stoker triple cranks 52/39/30 (170mm) incl timing: 1005gm
1- BB6700 (bottom bracket included in the set) : 95gm
1-spacer bag incl crankarm bolt: 30gm

TOTAL SET: 1890gm *

* That puts this Ultegra set squarely between the FSA SL-K and the heavier Gossamer MegaExo set, per the FSA website specs.

FWIW, here's a brief of all the tandem sets from the FSA website:

SL-K LIGHT TANDEM Crankset

BB30: 1350 g (Set)
MegaExo: 1571 g (Set)

* not sure if these weights include the BBs (ie: 108g * 2 = 216)
