Efcient Pedaling: In order to provide efficient pedaling, FAST relies on both ideal anti-
squat values as well as the flexible carbon stays. As the suspension moves away from the sag
point in either direction, a force is created from either compressing or extending the stays.
This force acts on the shock and helps return it back to sag. This provides a stable,
responsive platform for pedaling.
Large Impacts: Support for large impacts is provided in two ways: decreasing leverage
ratio and carbon flex. The leverage ratio is decreasing which makes it progressively harder
to compress the suspension as it moves through the travel. The carbon stays add to this by
contributing an additional spring force as they are extended through the travel.
Small-Bump Sensitivity: With the pedaling performance and large impact support
handled by the linkage design and flexible carbon stays, the shock can be run with
minimal compression damping. This frees the shock up to remain active and absorb
the smallest of bumps.
FAST, or Felt Active Stay Technology, is a linkage-driven, single pivot
system with exible carbon stays. By replacing the pivot near the dropout
with exible carbon stays a lighter, stiffer, and overall snappier frame
can be made.
COMPRESSED
0% Travel (Top-Out): In order for
the suspension to reach full extension,
the rear triangle is required to
compress.
EXTENDED
100% (Bottom-Out): As the
suspension gets deeper in the
travel, the rear triangle is required
to extend.
NEUTRAL
30% Travel (Sag): At the sag
point (approximately 30%), the
rear triangle is neutral.
