Fox Racing Shox has issued a warning to those using or considering using their suspension forks for anything other than the 26 inch wheels they were designed for. (This does not include the F-29, obviously) Here is an excerpt from the story as posted on Bicycle Retailer and Industry News:

Use of Fox forks with any tire larger than 26 inches, such as a 650b tire, will subject the Fox fork to loads and forces it has not been designed or certified to meet.

Go here to read the rest.

The problem is stemming from the popularity of Fox forks primarily with the 650B proponents who have found that the larger wheel size will fit in forks manufactured by Fox for 26 inch wheels. As Fox states, “Unauthorized and unapproved use of these forks with tires larger than 26 inches may result (in) accidents, causing serious bodily injury or death.”

Twenty Nine Inches would like to remind our 650B fans that White Brothers does make a 650B specific fork that is approved for use with this wheel size.
