    170mm Spacing Fork?

    I was wondering if such a thing exists. I like the idea of being able to interchange front and rear wheels, but that concept seems to be limited to 135mm. Of course, my bike has 170mm rear and 135 front.

    I tried to use the search feature, but turned up nothing. Anyone ever heard of one? Apologize in advance if a thread has already covered this recently.

    Never heard of one existing; custom if so.

    Makes me wonder however, just how much actual use that the ability to swap front and rear sees.

    Having it makes sense where there may be a need/desire of knowing that it is there.
    Just like Fat Bikes...the posters on here can go anywhere...and do.

    Honestly, I just like the concept of standardization. Plus, with sliding rear dropouts, I can imagine having a cog on one for trail and a cog on the other for commuting.

    Can be done as a custom option. I'm building up a rig with 190 F/R. One will be xx1 the other set up 9/10 with a ss cog. That way if I freeze up or otherwise kill the xx1, I can make it out on the ss. In summer the bike will have double duty as geared/ss on rabbit holes. Hard part has been sourcing 190 TA hubs as singles as everyone wants to sell them as a 190/135 pair.

    I'd love to see this when you're done. I wonder what kinds of structural issues you start running into with such a wide fork, at a reasonable weight. Will a standard 1-1/8" steerer be adequate or would a stiffer taper design be required? I'm curious, are you planning to have the custom fork made with additional truss support? Also will the fork shoulders be able to clear the down tube when cocked beyond 90 degrees off center?

    I'm really thinking aloud. What are your thoughts? And good luck with the build

    Going to be a tapered headtube with trusses. Fork shoulders won't be an issue but the trusses will hit if turned much past 110* or so. My ss has a truss fork on it and I've hit it few times in the past 6 years without issue.

    You should be able to buy a pair of 190mm Hope hubs from any shop that deals with QBP. The endcaps are their standard endcaps....easily swapped for a 10mm thru-bolt.

    That said......where are you going to find a 190mm thru bolt???

    Can you not get a 135/170 hub with switchable end caps?

    Frame builder is going to make it. He just made a couple for a 170 project he did.
