    Default Fox 650B Warning

    After reading about the new 650B tire size, I started looking around and found this warning over on 29".com and on BRAIN.

    Fox Racing Shox Warning to Customers

    WATSONVILLE, CA (BRAIN)—This is a warning against unapproved use of Fox Forks from Fox Racing Shox.

    FOX 32, 36, and 40 suspension forks (with the exception of model F29) are engineered and tested for use with 26-inch mountain bike tires. These models meet CEN and AST M testing standards based on use with 26-inch tires.

    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.

    Fox 32, 36, and 40 suspension forks are not recommended or approved by Fox Factory, Inc. for use with tires larger than 26 inches, either as original equipment or aftermarket, according to Fox's Elayna Caldwell.

    Unauthorized and unapproved use of these forks with tires larger than 26 inches may result accidents, causing serious bodily injury or death.

    That's good to know. I've "heard" of stories of folks converting their 26er fork to a 29er.

    If there is enough to worry about , then that must signal the arrival of the 650B.

    There is a guy doing them on MTBR. He's done a Fox 40 and I think a 36?

    I'd be really nervous to grind away that much material on an expensive fork.

    People are saying a 650B will fit on a standard 26" Fox fork without grinding. I looked at my Yeti set-up with the TALAS and I'm not seeing an extra 1.5" with tire clearance. But it's been done, so

    That does read like it was written by a team of lawyers.

    Will a 650b wheel fit in a 26 inch fork? If so, do you have to actually modify it to fit?

    Wouldn't it be 3/4" either side of the axle ?

    I heard 26" inch wheels fit fine with the current Fox forks, so there is in fact no need to even try to fit 650b's in there.
    Gone for good. PEACE.

    The latest MBA article on 650b says they fit most standard 26er forks. Still, using a part beyond what it was designed for isn't the best idea IMO.
