    Hardrock SD 2012 + MT55 29er F Wheel + Rock Shox Revelation 29er. Will it blend?

    So i got a Hardrock Sport Disc 2012 26
    http://www.specialized.com/br/pt-br/...portdisc#specs
    and im planning to upgrade it to 29er wheel up in front and a good suspension fork. Will the Shimano MT55 29er MTB Disc Front Wheel 15mm Axle (theres a 9mm QR version as well specs listed below) + Rock Shox Revelation 29er 140mm go with my Hardrock frame? What about the axles difference, what should i look for?
    The Rock Shox Revelation 29er 140mm seems a great option but not sure if the mt55 wheel will fit. Is there a specific version of those components i should look for to fit my frame?
    Yeah, i intend to upgrade it with a smooth long travel fork and a 29er wheel on front due my riding style and personal preference. To make it clear I wont buy a new frame or bike

    Any input on this issue appreciated,



    Rock Shox Revelation 29er 140mm:
    Dropout options are wisely restricted to 20mm Maxle Lite for better steering precision, though, and RockShox will offer this new fork exclusively with tapered aluminum steerers.

    First off, you'll void your frame warranty with that long of a fork.

    Second, the 26'er frame geometry wasn't designed for a 29" wheels(front or back).

    While the Hardrock frames are known for being bomb proof, you're increasing the amount of leverage on the headtube with both a taller wheel and a longer fork. It may not hold.

    If you took the money you're going to spend on a revelation, a wheel, and a tire you could buy a new 29er.

    If you don't know if or how the fork will fit to your frame you are in over your head.

    This creation will handle like ****.

    enough ?

    nop, thats your guess <> fact

    theres no specialized 69er, and from my experience after riding my 26er, an inch or 2 more at the front will actually be better for my riding style and height. Now have a good one.

    Looking for someone with experience on those components.

    Its not an "inch or 2". You've got 3" increase in wheel diameter PLUS you're talking about going from an 80mm fork to a 140mm fork. Thats another 3 inches.

    I wish they made a revelation that would fit your frame so you could actually do this

    New question here.

    3 on the wheel, not wheel height.

    Why do you suppose a 80mm travel fork is 60mm smaller than a 140mm travel one. The travel course is 60mm smaller but i think you got it, right? I cant seem to find the exact geometry of those forks tho, point it to me, will ya? Also 6cm <> 3 inches.

    Sorry, I know math and Ive read about some types of conversions, not all headtubes are the same. Anyway help me by suggesting another smooth long travel fork if you are sure there's no way to fit a rock shox revelation into a hardrock frame.
