Installation Instructions

It is extremely important that your ROCK SHOX fork is installed correctly by a
qualified technician with proper tools. Improperly installed forks are extremely dangerous and
can result in severe injuries.
1. Remove the existing fork and lower headset race, cut ROCK SHOX steerer tube to length
using the original fork for measurement. Note: Do not thread down ROCK SHOX steerers
more than 15mm since the tube diameter is reduced below that point.
2. Install the headset race (Ø 26.4 for 1" steerers) firmly against the top of the fork crown.
Install the fork assembly on the bike. Make sure there are sufficient threads to properly lock
the headset in place. On threadless steerers (Aheadset design) make sure there is sufficient
length to properly clamp stem (refer to stem manufacturer's instructions). Adjust the headset
so no play or drag is felt.
3. Install the brakes as per manufacturer's
instructions and adjust brake pads properly.
4. On threaded steerers, insert stem to a minimum
depth according to CPSC and JIS standards. The stem
must be inserted to a minimum engaging length not
less than 2.5 times the stem diameter from the
lowest end of the stem (not wedge, see Figure 1).
5. Fit a brake cable to the ROCK SHOX fork brace
mount. Do not route the cable through the stem or
any other mounts or cable stops! The cable should
Figure 1
make a direct route from the brake lever to the ROCK
SHOX fork brace mount and be able to freely move up and down 50mm with the suspension
movement. It may be necessary to install a whole new cable.
6. TIRE CLEARANCE: Maximum tire size is 2.2" wide or 335mm radius. Be sure to check
this radius whenever you change tires. Exceeding this maximum will cause the tire to jam
against the crown when the forks are fully compressed. An easy way to check tire
clearance is to remove the elastomers from both fork tubes (see tuning section) and
compress the legs fully. A minimum clearance of 1/4" (6.4mm) is necessary. QUADRA 21R:
The upper tubes must always be fully engaged in the crown. The upper tubes must not
extend above the crown more than 3mm.
7. Check the clearance between the down tube of the bike and the ROCK SHOX adjuster
knobs and/or the cable mount. If possible, adjust the handlebar height so that the handlebar
