Determining Tire Size - With the tire installed and inflated on the
rim, measure the following three
dimensions.
Maximum Peak Tire Diameter = 343mm = 27.00 inch
Maximum Edge Tire Diameter = 326mm = 25.67 inch
Maximum Tire Width = 61mm = 2.40 inch
Do not use a tire if ANY measurement exceeds the maximum
dimensions shown above. Using tires larger than the dimen-
sions
shown above is NOT RECOMMENDED and can cause serious
or fatal injury.

Brakes
Linear-pull Brakes
Linear-pull brakes (i.e. V-brakes) can be used on FOX FORX. Use only the FOX brake posts supplied with the fork.
Install brake posts and torque to 80 in-lbs. Install and adjust linear-pull brakes according to the manufacturer’s recom-
mendations. Test brakes for proper operation on flat land. FOX FORX use a hangerless lower leg design and cannot
use any cantilever style brakes.

disc brakes and torque all fasteners according to manufacturer’s recommendations. Install, route and check that all
cables or hydraulic hoses are securely fastened to the lower leg and will not move during compression of the fork. Test
brakes for proper operation on flat land.
Maintenance
Performance, safety and the life-span of your FOX FORX depend on maintenance. If you ride in extreme conditions,
service and maintain your FOX FORX more frequently.
NOTE: In this manual, reference being made to the left and right side of the fork is from the seated rider’s perspective.
