    Fox 40 / Mavic DeeMax axle questions

    My digital caliper battery died & I don't trust my tape measurement. I wanted to measure the front axle on my 2011 or 2012 Fox 40 Fit RC2 that came on my used 2011 Santa Cruz V10.4 . I am using an older Mavic Dee Max wheelset . Anyone know if this wheelset circa 2011-2013 might use a 20x100 or 20x110 hub? Are spacers specific for this brand? The rear is supposed to be designed for 12x157 as per SC, so I presume the Dee Max has an adapter on the rear hub to convert it from 12x150 to 12x157. Thanks.

    Never mind, borrowed some calipers and got my answer.

    For future reference, any 20mm T/A will only be 110mm long (20x110). To the best of my knowledge, there has never been a 20x100mm axle. Ttyl, Fahn

    Thank you Larry. I see some ads for wheels with hubs for 20x100 so I was
    confused. I confirmed my fork will take 20x110, but the rear is tricky. I am
    measuring 150 with the wheel mounted, but the derailleur hanger takes up around 7mm. SC’s website for the V10.4 states 12x157 spacing. The hub is an older Mavic Dee Max. Any wheels I buy that are 12x150 may require me tonget a 157 axle conversion kit (e.g. Azonic).

    Got an email from SC, they said the 157mm is an error and will fix the webpage.

    Good. 157 is boost and usually you'd need a new hub/wheel. I've heard of spacers being made for some hubs. But I'm not sure about boost 157.

    Not really. 157 is common on DH bikes except for specialized who uses 135. It also fits new pivots and is sometimes called “super boost”. 148 is the boost standard.
