    New question here. Do Boost 29ers 148mm accept 150mm hubs & Are those 15x110 hubs cmpatible with 20x110?

    Hi
    Are those 2mm on the hubs tolerable due to frame flex?
    Why haven't those hubs been made just lighter versions of existing 150mm dh hubs?

    Which forks and hubs are 20x110mm ready/compatible?


    ps. I would like you to give me negative comment for the red chicklet thing to be darker red tint or something, but the thread is serious, just the repuation thing istn't.

    148 to 150: nope, it's a snug fir

    20 x 110? Its 15 x 110mm and Rockshox, Fox and Manitou definately make forks. Hope and Sram definately make hubs.

    Having just got a bike that's boosted I'm a total convert, wheels are stiffer, bike feels better

    Nope, and I'm still trying to figure out which you'd be installing - I'm assuming a 20x110 front hub?

    The 150 hub still has the old distance between the flanges. But the brake rotor is mounted out away from the flange. It may not line up exactly with the caliper without some adjusting.

    I have a huge doubt on this subject.
    To a boost 148/110 bike, what's the right/best option to the front hub? 15/110 or 20/110?
    I'm looking at Stan's ZTR website and some models, like Arch Ex, have both options, and other models have only 15/110...

    This is really confusing to me. So many options. And what's the point in use a boost fork, but mount a less stiff hub?

    Thanks in advance.
