The
winningest time trial crank in history.
With truly nothing inside, Neo Pro is a showcase for the amazing potential of
composite materials.
Hollow
Carbon delivers the lightest, stiffest, smoothest and strongest
components possible.
The cross section of the the arm is wing-shaped, and the back of each arm is
partially recessed to cover the
Ceramic Bearing BB cup. This design will become the new standard for
those who demand the fastest crankset available.
When looking at the FSA Neo Pro Crankset, we're not
only seeing the crankset that Fabian Cancellara took to victory at the UCI Time
Trial World Championships, but possibly the crankset of the future. Aero shaped
arms and an enclosed spider offer lots of possibilities. But time trial cranks
are not about the future. They're about now. About shaving the bike to the bare
minimum, saving seconds by reducing drag, and putting maximum power to the
chain, to the cassette, to drive the wheel and take the rider aboard to victory.
Or at least a personal best.
If you think you've seen this crankset before, you're wrong. While the outer
chain ring is familiar, this is FSA's first through-axle time trial crankset.
The carbon fiber arms and spider are produced via the same process as the
ultra-light K-Force Light crankset. The arms are hollow for weight savings and
carbon fiber for strength. But to that hollow-arm shape, the frontal area has
been reduced to about half the thickness of a standard FSA crank and the arms
molded into a wing shape by the pedal threads. The wing is designed to smooth
out the airflow around each crankarm at the top of the pedal stroke, where the
crankarm is being forced through the air faster than the bike. This is why there
is more material behind the pedal hole when the crank is at the top of the
stroke; the left arm is a mirror image of the right. As the right arm passes 9
o'clock and the left arm 3 o'clock, they are going into the wind faster than the
bike and are doing so at speed that picks up to 12 and then starts going down
'til 3 o'clock on the right and 9 on the left and then starts going with the
wind for the remaining 180-degrees of their rotations. The arms are also
designed to cover the external bottom bracket cups to smooth the airflow over
the bottom bracket as well. The spider is solid so there is no work created by
the arms moving through the air.
Completing the cranks is the FSA solid chainring. Right now, this is specific to
the Neo Pro and is ribbed for strength, thinned for lightness, and pinned and
ramped for faster shifting.
The world's fastest crankset spins on ceramic bearings, specifically the FSA
MegaExo Ceramic BB. Because this is a special-use component designed to go as
fast as possible, the bottom bracket with the lowest drag has been selected to
complement the cranks. The MegaExo Ceramic Bottom Bracket has an alloy center
sleeve with double o-ring seals, external oversized ceramic cartridge bearings,
and forged and CNC'd alloy bearing cups. The cups are anodized red. The bottom
bracket is available in both English and Italian threads. The BB weight is 92g.
The FSA Neo Pro crankset is available in 130mm BCD only. The cranks are a
moncoque carbon fibre design. The right arm and spider are fixed to the 24mm
chromoly integrated spindle. The outer chain ring is a carbon/AL7075 mix. The
inner ring is AL7075. The chain ring bolts are alloy and take a Torx T-30
driver.
