FSA: SL-K Carbon Cranks
Construction:
The
FSA sl-k carbon cranks use the same pressurized molding process
as the K-force with an internal I-beam reinforcement to offer higher
tortional strength then previous sl-k carbon cranks. The carbon
is glass fiber enhanced to create the stiffness of the K-force light,
at a lesser cost.
It creates a crank arm with a traditional carbon black UDF gloss
finish unlike the distintive "thatched" or woven appearance
of the K-force crank arm that helps to identify their top of the
line option.
The chainrings are fabricated out of AL7075 using CNC technology
for added accuracy, with a black face and silver lasered logo. The
chainring bolts for the sl-k cranks are an AL7075 Torx T-30 alloy
identical to the FSA K-force light crank.
Bottom Bracket:
The BB, uses oversized cartridge bearings with a 24mm integrated
CrMo spindle. Anodized alloy external bearing cups hold it all in
place. Note that this is typically sold with the standard Mega Exo
BB NOT the Ceramic Mega Exo BB which adds another $120 to the cost.
