    Upset Is the 20mm axle dead?

    I was looking at forks with 20mm Axles & its seems they no longer exist for single crowns. I would like to be able to use the same wheelset & switch between a DC & SC. I hate all of these new standards!

    yeah, you're about 7-8 years late with that. There haven't been any 20mm single crowns for a while.

    You could just get a convertible hub; they're still pretty common.

    If you want to buy a brand new single crown, the only 20mm choice is a Fox 36. I've been looking and that's all I can find. Nobody seems to stock them but it's an option you can build on the Fox site, which usually means big $$$$.

    X-Fusion Metric (180mm SC) has a 20mm axle according to their site but I've never seen one in person. I've heard X-F has really taken a huge step up in quality, this may be an option?

    No.

    X-Fusion Metric.

    I've owned 3 now on different bikes and keep coming back. Flawless. Win.

    For single crown there are not many options for 20mm axles. It's a pity because the performance benefits far outweigh the couple of grams weight penalty when you get into harder riding. The difference in weight is very minimal when you compare a 110x15 axle to a 110x20 axle. Previous comparisons have usually been 100x15 axle compared to 110x20 axle.

    The only forks I can think of are
    Bos Deville
    X-Fusion Metric
    X-Fusion Revel
    Fox 36 - 26 and 26 831
    SR Suntour Durolux

    You might want to check if some E-Bike specific forks come with 20mm axle versions. Although they will probably be too heavy.

    When I started riding you either had 9mm Quick Release (10mm bolt on) drop out axles or 20x110mm drop outs.
    Now we have Quick Release (only really used on cheap bikes), 15x100, 15x110 (boost), 20x110mm, and 20x110mm (boost).
    With 20x110mm boost the brake caliper has a different offset. So you need a 20x110mm boost hub to match the rotor with the caliper offset. This allows them to push the spoke flanges further out increasing wheel stiffness laterally.
