Our Downhill forks (Race, Team and World Cup) are factory tuned for a 73 to 83 kg. (160 to
180 lb.) rider. The Boxxer Ride is factory tuned for a 68 to 79 kg. (150 to 175 lb.) rider. These
forks can be to many different rider weights or riding styles. You can tune this fork to benefit
your needs by changing preload, internal coil springs, rebound damping and low or high speed
compression damping.
Changing the Spring Rate (Race, Team and W orld Cup)
If you are bottoming out too often or not using all the available travel then the overall
spring rate should be changed. The standard spring rate (yellow) is designed for the
160-180 lbs. (72-85 kg.) downhill racer.
You may change the overall spring rate by
changing the main coil spring in each leg with one that is softer or firmer than the
s
tandard spring. By changing the coil springs, you alter the overall spring rate.
RockShox has designed nine spring configurations for the Boxxer. By changing the
springs in either one or both legs you can tune the bike to your specific needs. Below
is a table that breaks down the spring rates into rider weight ranges. Use this table as
a guide when choosing a different spring rate than the one provided in the fork.

Setting Sag
The Boxxer is designed to compress (sag) when you are sitting on the bike. This sag
allows the front wheel to stay in contact with the ground when braking and cornering
over rough and uneven terrain. Optimum sag is between 15 and 25 percent of tota
l
fork travel.
To measure sag, install a zip tie on the upper tube so that it is flush against the seal; sit
on the bike in normal riding position; then step off the bike and measure from the bottom
of the zip tie to the top of the wiper.
This measurement is sag.
The preload can be changed by adding or removing preload spacers into the main coil
spring stack.
