To all FOX Racing Shox Users and Customers:

WARNING

It has come to the attention of FOX Racing Shox that certain individuals and / or entities are modifying FOX forks to accommodate mountain bike wheel sizes other than those having 26 inch nominal diameter. One such modification includes removing material from the lower leg cross bridge in order to fit a 29 inch tire in the fork. Such modification will ultimately separate the lower fork legs at the cross bridge (i.e. the weakened cross bridge will fracture) and may cause bicycle instability and crash that result in SERIOUS INJURY OR DEATH.

DO NOT MODIFY OR MISAPPLY FOX FORKS

NEVER REMOVE MATERIAL from any portion of a FOX fork. USE ONLY 26 INCH WHEELS with FOX 32*, 36 and 40 bicycle suspension forks. Those FOX forks are designed and tested for use ONLY with 26 inch Mountain Bike wheels / tires. Use of FOX forks with any wheel other than 26 inches and/or alteration or modification of any FOX fork will subject the FOX fork to loads and forces it has not been designed or certified to meet and will void all warranties. The FOX 32*, 36 and 40 models meet CEN and ASTM testing standards ONLY when used with 26 inch wheels / tires and are not recommended or approved by FOX Factory, Inc. for use with wheels larger or smaller than 26 inches, either as original equipment or aftermarket.

DO NOT RIDE ON MODIFIED OR MISAPPLIED FOX FORKS

Proper forks are critical to proper bicycle handling and stability. Improper function or failure of a bicycle fork while riding can cause a bicycle to become uncontrollable and result in a crash. Use of FOX 32*, 36 or 40 forks with wheels larger or smaller than 26 inches, or any other modification, may cause crashes that result in SERIOUS INJURY OR DEATH. Never ride a bicycle that is, or appears to be, fitted with a FOX 32*, 36 or 40 fork that has been modified and / or fitted with any wheel larger or smaller in nominal diameter than 26 inches.

* DO USE THE RIGHT FORK FOR THE JOB

For those of you who want to ride on 29 inch front wheels with suspension, FOX offers the 32 F29 fork designed specifically for 29 inch wheels. The F29 is available in 80mm, 100mm or 120mm travel configurations and is ideal for tall wheel applications. The F29 is the only FOX fork available for use with 29 inch wheels and is clearly labeled "F29" on the right leg. The F29 should be used only with 29 inch wheels. As with all FOX forks, do not modify or misapply, or ride on improperly applied or modified FOX F29 forks.

DO CONTACT FOX

Do not modify any portion of a FOX fork and do not purchase or use any fork that appears to have been modified. Any FOX 32*, 36 or 40 model fork that appears to accommodate a tire larger than 26 inches in nominal diameter, such as 650b or 29 inch, should be avoided. If any doubt exists as to the originality or proper application of a FOX fork please contact a FOX representative.

Thank you,

FOX Racing Shox

From the few that I've seen. I'm jealous. Fox is just missing the boat on a longer travel 29er market, in my opinion. We're all dyin for more travel and the fork manufacterers are a little slow to meet such demand. We all know it's there.

The stability and separation issues would me more of a concern to me for those that are not a thru axel. No way would I ride a fork without one now.

Don't leftys have less material than a modified 36 or 40? Are they weaker? They seem to do fine with only a thru axel....

Just my $.05
 
dildog, I did read it. I was commenting on the fact that there forks have broken at the leg cross bridge without any modification being done to it. So mod or no mod, your still running the same risk, although yes it is a higher risk with a modified fork.
 
In my point of view, the cross bridge has just been mentionned as one of the fox fork's weak point by the general marketing manager of this company. It is always at the weak point that material will fail if under enough pressure, so if the modified fork can brake there, it means that if it has to break in normal condition, it will break at this same area. I know a guy who has rebuilted a pile of those forks, could mention some other weaknesses. One of them is the seal/wipers system not efficient enough to keep dirt outside of the critical internals resulting in oil contamination & wear. Some internals are designed only to have a certain life time. would be very technical to explain.
 
Fox is really pushing out these legal press releases as of late. Probably to avoid any of the past legal stuff they've had into developing into future legal battles.....not taking sides, just postulating.
