    Welding a Cracked Reynolds 853 Frame? X Post

    I know that for liability reasons a manufacturer will say "no", but can a competent welder repair a crack in an Reynolds 853 frame?

    The drive side drop out on my 3 year old Niner SIR9 has cracked all the way through. A buddy told me that instead of repairing the crack itself, the entire dropout could be replaced.

    Hope this is a possibility, if not then it's time to move on.

    Yes it can be fixed. (well, having not seen it, I'm 99% sure) Find a builder you like and get on it.

    OTOH, it's always possible Niner might have a crash replacement that would cost about the same or less.

    Thanks, Feldybikes. Niner's crash replacement price is 20% off retail. I was hoping it was a bit more than that.

    I'm guessing I need to find a good frame builder to do the work vs a local machine shop who probably won't understand the need to see that the new dropout is properly lined up & straight.

    Custom motorbike shops are a good place to start. Just make sure they're aware of how thin the tubing is so they don't blow holes in it.

    If you do some searches, you'll find many solutions on how to repair that crack. It's very common that those Niners crack there.
    May the air be filled with tires!

    Yeah, I would, too. I guess I stand corrected.

    it would really help if you would post pics. I suppose some people know where this cracks if it is a design defect, but for the rest of us pics are essential. Most steel dropouts can be repaired by welding if the crack is in a convenient place.

    You, sir, are correct. As they say, pics or it didn't happen!

    Easy fix. Get rid of the paint, weld the dropout crack shut, put a piece of place joining the whole dropout/chainstay/seatstay area. Done. $50 job if I was doing it, and I could do it while you waited.

    If you want it to look swanky, of course, you're in a whole different ballpark. Remove the existing dropout, replace with something similar, repaint - you could spend $500.

    So if you just want to ride it, start calling builders in your area. If you need it to look original/perfect, forget it.

    find someone that can tig weld and have them do it. Don't go to a framebuilder that will braze it, and some will if they don't TIG
