    hi all

    why don't company's make a universal legs for forks?
    adaptor who can let us use 26 or 27 wheels on our bikes. without the need to buy a new fork.
    and if you think about it, you can do it also on the bike frame, for the rear wheel.

    why bothering with making an adapter when we can sell you 2 forks?

    but,
    I guess the company who will make their forks with the option of using both size wheels,
    will probably sell more forks then the company's who won't.... no?

    That's for 15 and 20mm hubs, most hubs are convertible these days so adaptors on the fork are pretty unnecessary IMO.

    Obviously a 650b fork will take a 26" wheel so if you're still bi-curious you could still use just one fork.

    you didnt understand me
    I know 27 fork will take a 26 wheel. but its taller by ~1 inch(?)
    why not have a fork, that can accept bot size wheels, with an adapter that can be flipped and make the fork lower\taller
    like this
    sorry for the terrible draw...

    Somebody will bitch about the weight, someone will bitch about the creaking. Besides that, what's the point of switching wheel size?

    the point?
    I'm on a 26 now. (like most of riders today ) and really want the new PIKE.
    but, what if I buy a 26 PIKE and after a year want to go 27?
    as I know, there is no why of just replacing the PIKE legs. you need a new complete fork.
    I can buy the 27 PIKE and use it on my 26er. but its taller. I don't want my AM bike to be taller in the front.

    On some forks you can just swap the lowers. I was going to do this with my RS Revelation, but ended up finding a good price on the complete 27.5 fork. Lowers cost around $250, and it's unlikely that used ones could be resold but it's still cheaper than a new fork.

    I just did that...bought a 26" pike and 3months later I snapped my frame...replaced it with a 27.5...sold the 26" pike for 700$ bought a new one in 27.5 for 850$..not really a big deal..

    Because there's not enough of a market for it. Most people are not switching back and forth between sizes and it doesn't make sense for them to build something like that. How many bikes or forks had 'adjustable travel' that nobody uses? Same thing. Most people have an idea about the bike they want to build or it goes on a factory built bike that someone buys and they don't don't care.

    It could be a clever idea, having a small insert that gave you an additional 5mm of offset alongside 10mm of added "axle to arch" clearance. Then flip it and it shortens offset and a2c.

    BUT I agree with the other folks...and unnecessary complication when most people are switching over for good, and besides, how else would they sell you 26 again in 3 years?

    There are probably some cost savings to be had, but we can only guess at their intentions.

    They do something similar w/ cranks - it's one crank drilled at different points for "length".

    Yes all 27.5 forks accept 26..
    This is a dumb thread.

    yes. 27 forks can accept 26 wheels.
    and you can use shoes that 2 sizes bigger than what you need.
    is it ideal?
    no.

    If you had a fork with 20 or 25mm drop outs, that were hexagonal (like manitou) and you had blocks drilled for 15mm thru axles, and had everything marked to index them for the different sizes it could work.

    Pinch bolts would be needed to hold things from rocking, and you would have 2 new Creek points. So, don't know if it's worth it.

    If you look past the wheel size mess and apply it to adjustable fork geometry (offset and height) that's a great idea.

    I'm still amazed nobody has messed with an eccentric steerer rod to mess with offset easily. May not be necessary with a triple clamp fork.
