I just bought a pair of these for a new road bike project, from
Bulltek Sports for $99... there isn't much data out there on them (not
even one picture anywhere on the web, even on FSA's web site), but I
assure you they exist. I thought I'd post some basic info.
In the 172.5 length with the standard 50 x 34 rings, they weigh 632g
with bolts, 595g without, according to my postal scale (pretty good
for hundred dollar cranks). The Q-factor appears to be the same as my
Ultegra double, which is roughly 149mm, although I have no way of
measuring this for either crank. (Nashbar sells the other cheap
compact crank out there; that has a 160mm Q.)
Appearancewise they look more or less like the Gossamer road cranks,
which you can search for on Google image search -- glossy black crank
arms, peened black finish chainrings with shiny metal teeth (just like
on the FSA Energy and Carbon Compacts). Smallish silver FSA logo near
the pedal hole and "Gossamer" logo near the spindle, not very
obtrusive. (I have photos if anyone wants -- just email me.) They have
sort of a hollow running on the reverse side of each crankarm, kind of
like old Ritchey or Truvative cranks, and unlike the smooth hollow
Ultgera arms.
