2018 36mm FLOAT forks can be travel adjusted by replacing the air shaft assembly. 36mm FLOAT NA2 forks can be reduced in travel as low as 100mm (831 air shaft). Certain 36mm FLOAT forks may have their tavel extended only if they were built with a damper that can be extended safely to the new longer travel. 36mm Speed-Ped-Elec and 831 forks can only be extended to have up to 160mm maximum travel.

36mm Speed-Ped-Elec forks are built with a stronger chassis to accomodate the extra weight of electric motor equipped bicycles. These 36mm Speed-Ped-Elec forks utilize thicker walled upper tubes and therefore have a reduced upper tube inside diameter. 36mm Speed-Ped-Elec forks are built with 34mm FLOAT NA2 air shafts.

When adjusting travel, you will change your air spring compression ratio. To tune your new air spring to feel the same as the original at a different travel, you may need to add or remove air volume spacers from the topcap. You can find instructions for changing air volume spacers in 36mm FLOAT NA2 forks by clicking: 36 FLOAT NA2 Air Volume Tuning ». The chart below lists recommended air volume spacers by travel. Never exceed the listed maximum amount of air volume spacers.

WARNING: Some damper and spring combinations are not possible. DO NOT attempt to extend travel on a 36mm FLOAT fork without first contacting FOX directly to verify that the damper and chassis of the fork can handle the new longer travel. Failure to do so may lead to an unapproved combination of parts that could fail, causing a loss of control of the bicycle leading to SERIOUS INJURY or DEATH.

WARNING: FOX products should be serviced by a trained bicycle service technician, in accordance with FOX specifications. If you have any doubt whether or not you can properly service your FOX product, then DO NOT attempt it. Improperly serviced products can fail, causing the rider to lose control resulting in SERIOUS INJURY OR DEATH.

WARNING: Never attempt to modify air volume spacers or air shaft assemblies, as this can damage your fork causing a loss of control of the bicycle leading to SERIOUS INJURY or DEATH.

WARNING: FOX suspension products contain pressurized nitrogen, air, oil, or all 3. Suspension misuse can cause property damage, SERIOUS INJURY OR DEATH. DO NOT puncture, incinerate or crush any portion of a FOX suspension product. DO NOT attempt to disassemble any portion of a FOX suspension product, unless expressly instructed to do so by the applicable FOX technical documentation, and then ONLY while strictly adhering to all FOX instructions and warnings in that instance.

WARNING: Modification, improper service, or use of aftermarket replacement parts with FOX forks and shocks may cause the product to malfunction, resulting in SERIOUS INJURY OR DEATH. DO NOT modify any part of a fork or shock, including the fork brace (lower leg cross brace), crown, steerer, upper and lower leg tubes, or internal parts, except as instructed herein. Any unauthorized modification may void the warranty, and may cause failure or the fork or shock, resulting in SERIOUS INJURY OR DEATH.
