  • Didn't really want to start a thread just to ask this and figured this seems like the best place.

    I don't really know a whole lot about steel frame fabrication other than steel can be repaired quite easily.

    So my question is this: Say I hypothetically have a very nice steel frame with 135 qr disc drop outs, if I really really wanted to, would it be possible to convert the frame to 142 thru axle drop outs?

    Is it feasible? Would it require what would effectively be a whole new rear end? Seat stays and chain stays would need replaced to?

    Anyone done this before?

  • Def feasible!
    Does it make sense? No
    Will it be cheap? Probably not

    You probably want to redo the disc brake tabs as well as alignment might be tricky to match and if you want flat mount you'd probably need to redo the rear triangle

  • Def feasible!

    Right, that's good!

    Does it make sense? No
    Will it be cheap? Probably not

    Yes, I completely accept that it's hard to really see any reason to actually do it since it would be very uneconomical. I just wanted to know if it would be possible but I realise that, if seat and chain stay were also replaced, it would probably be approaching the cost of what having a whole new frame made would be.

    Of course, this is all just hypothetical. Only an idiot would seriously consider it, right? :)

    edit - yeah part of the thought included switching to flat mount too
