GENERAL SIZING GUIDELINES BY RIDER HEIGHT

Medium – Riders 5’6” to 6’ (168cm to 183cm)
Large – Riders 6’ and up (183cm +)
FOES Shaver FRAME GEOMETRY
Sag can be measured at the rear wheel’s axle or at the shock. These instruc-
tions approach this measurement at the shock. Your FOX Shock should have
5/8” to 3/4” (5.75” travel) of sag when the rider’s full weight with gear is at rest
on
bicycle. The best way to do this is to have someone check the total length
of
your shock, eye to eye, while you are feet on the pedals and balanced on
the
bike on level ground. You can use a nearby wall to assist you in your
balancing… but don’t lean against it – this will give a false measurement.
Next (or first), measure the length of your shock at rest (bike lifted at the rear
and allowing the shock to fully extend). The difference of these two measure-
ments is your sag.
SETTING TOTAL SAG
To
adjust the sag you must adjust the spring’s preload. This is done by
unlocking (loosening the ring’s allen set screw) and turning the retaining ring.
To
get more sag turn the ring counter-clockwise (this will extend the spring).
To
get less sag turn the retaining ring clockwise (this will compress the
spring). Be sure to re-lock the retaining ring! Only through spending the time
testing and re-testing will you get proficient at sag setting. Foes recommends
that you do not touch your sag until you are very familiar with how your rear
suspension works and feels.

Seat Post Diameter: 31.6mm
Head Tube Diameter: Top 1 1/8” 44mm Z.S headset only
: Bottom 1.5” 49.6mm headset only
Fork Type/Length: Shaver was designed around, and works
best with a 5” or 6” single crown fork. NO DUAL CROWN FORKS!
Use of Dual Crown Forks on the Shaver will void all warranties!
Front Derailleur: 34.9mm Top Pull
Rear Hub Spacing: 142mm x 12mm Thru Axle Hub
Disc Brake: The Shaver accepts a standard 6” I.S. rear caliper
mounted on the swingarm. Use of larger rotors requires the appropri
ate manufacturer-sized caliper adapter.
The Foes Shaver is a full suspension bicycle! It has 5.75” of rear travel, and
was designed as an aggressive trail bicycle. The Foes Shaver is not, by any
means, a freeride, jumping, or stunt riding frame. It is made for trail rides that,
at one point or another, require the full amount of travel of the shock. The
Shaver was made for riders who want to take advantage of longer wheel
travel, yet want the lightness for long climbs. This is the reason it is designed
around a single crown fork. Therefore, a single-crown fork between 140 and
160 mm works well with this frame.
If you bottom out your shock on a regular basis, you are undersprung or have
too little air pressure in your shock, and will damage your frame and shock.
Bottoming your shock on a consistent basis is considered by Foes to be
improper care of your bicycle frame and shock, and will void the warranty for
both, and all other warranties. If you bottom your shock consistently,
STOP!… and first check to make certain you have proper air pressure in your
shock. (It is vitally important to check the air pressure on the FOX
FloatAIR Shock EVERY TIME YOU RIDE.) If you have proper air pressure,
then your shock is either undersprung, or it has a problem. At this point it is
extremely important to not ride the bicycle, and make plans to get the shock
to a Foes technician to have it checked out and/or sprung correctly.
GENERAL SETUP
CAUTION! YOU WILL DAMAGE YOUR FRAME AND SHOCK IF YOU DO
NOT CORRECTLY SET UP AND MAINTAIN YOUR REAR SHOCK AND
SUSPENSION.
