SPV SET-UP QUICK REFERENCE GUIDE
1
SPV PRESSURE:
Start by pressurizing the red Schrader valve to the following percentage of your body weight:
Pounds and PSI
50-70% of your body weight (between minimum 40 and maximum 175 psi)
for shocks
30-40% of your body weight (between minimum 40 and maximum 175 psi)
for forks with SPV or SPV Evolve
35-50% of your body weight (between minimum 40 and maximum 175 psi)
for forks featuring Snap Valve SPV
Kg and Bar
7.5-10.5% of your body weight (between minimum 2.75 and maximum 12 bar)
for shocks
4.5-6.5% of your body weight (between minimum 2.75 and maximum 12 bar)
for forks with SPV or SPV Evolve
5.25-7.5% of your body weight (between minimum 2.75 and maximum 12 bar)
for forks featuring Snap Valve SPV
More pressure will create more compression damping, hold the bike up more, and pedal better.
Less pressure will create less compression damping, allow more sag, and be suppler.
2
SAG:
Set your air pressure or use the main spring of your fork or shock that corresponds with your
normal sag range (approx 25-40% of travel, depending on application. DH requires more sag
while XC riders typically run less). For shocks, your main spring air pressure can go up to 300 psi
(21 bar) so start with a higher pressure, sit on the bike to measure sag, and decrease pressure
until approximately 1/4 if your travel is taken up by your static weight. Ride, then make minor
adjustments according to your preference if necessary.
3
SET SPV VOLUME:
You should begin with the red 16 mm volume adjuster completely backed out (NOTE: 3-way
rear shocks and Snap Valve SPV lack this adjustment). Go for a ride. If you feel you're
bottoming out or that your suspension feels too linear (ie. it doesn't ramp up enough) turn the
volume adjuster inwards 1/2 a turn at a time until the rear shock or fork resists bottoming
while maintaining full travel.
THINGS TO REMEMBER:
Max Air Can Pressure for Air shocks: 300 psi (20 bar)
SPV Pressure Range: between 40-175 psi (2.75-12 bar)
Note: This information will get you started, but riding styles and preferences differ greatly, as
do frame designs and leverage ratios. Because of these factors there is no magic computer that
can input your weight and output your optimal settings. Within these ranges, play with your
adjustments until you find a setting that you like.
