FAST EXPLAINED
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.

FAST EXPLAINED
CONT.
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.

SHOCK SETUP
It is very important to have the correct amount of sag so that the suspension can be in the
part of its travel that is most efficient and compliant. Felt recommends starting at 30% and
adding/subtracting up to 5-10% to fine tune to your personal preference.
To measure sag, follow these 4 steps:
1. Push the o-ring to the top of the shock shaft.
2. Sit on the bike with the seat at full ride height to compress the shock. Bounce a few times, then push the
o-ring back to the top of the shaft.
3. Gently get off the bike, taking care not to change the position of the o-ring. On some shock models, the
sag gradients will be printed on the shaft. In this case, simply read your sag percentage as it is printed on the
shock shaft. If there are no sag gradients, measure the distance of the o-ring from the top of the shaft. To
achieve 30% sag, the o-ring should be 17mm from the top of the shaft. If there is too much sag (>30%)
add air pressure, if there is not enough sag (<30%), reduce air pressure.
4. Repeat process until desired sag is achieved.

FLIP CHIPS
The geometry can be adjusted by rotating eccentric chips located in the
seat stay pivot. By changing the orientation of these chips, the bottom
bracket height will be raised or lowered by 10mm and the head angle
will be slackened or steepened by 1 degree.

HEAD TUBE CABLE GUIDES
The head tube cable guides contain rubber reducers for all cable sizes
that are interchangeable and can be arranged to fit each rider's setup
and personal preferences.
