    Need advice on replacing downtube Trek 930

    I have a 1992 or possibly a '93 Trek 930 Mountain bike, 22" frame. I am considering replacing the downtube, it had a crack in it, but we redneck-welded a peice of pipe over it.

    The left rear stay is a bit dented but I think that will survive ok.

    What is the market range for something like this, excluding shipping? I also live in CT, and would consider taking it locally to someone here. I know Yellowjersey does repairs, thanks for any input. I know it's not a super high end frame but it is OX True Temper DB and it rides pretty well.

    Thanks!

    You can typically find a complete 930 for $100 with a little patience. Or $50 with a LOT of patience. Frame alone might be harder to find, but I'd guess $25-50.

    That's probably more sensible than having a frame builder look at it. Take the old one in for scrap value or make some kind of Alt bike with a little more redneck welding on the old one.

    Yeah I know, but it was my wedding present from my ex, and it has memories. It's also a hard to find 22" level top tube . I don't like compact frames.

    Been a long time since I've looked at tube replacement, but I think it's around $125 + repaint ($200+). Not going to be cheap.

    Typically about $150 pre tube without paint costs.

    IIRC, the 930 MTB frame was a generic TIG welded import. Unless it has sentimental value you'd probably be better off replacing it.

    They were lugged for the first couple of years. Pretty nice True Temper frames.

    I always assumed the 990, 970, 950, 930 were all the same frame, just different parts hanging off 'em. If that's the case then he's got the best steel MTB frame Trek offered for the year of his bike.

    I'm not a builder but your g/f is better getting a new bike, you can get the whole bike maybe for 150 bucks?? Personally i would not even bother in repair that bike, sometimes sentimental value goes way over the market price and this is one of the good examples of it.

    Depending in where it is broken you can replace the tube or put a sleeve to it, i have seen this a few times already but the "torch man" should be really good with brazing.

    "It's also a hard to find 22" level top tube" <-- I doubt that frame came with reynolds or columbus, even doubt it came with a "full set" of true temper tubes, more likely maybe 3? As long one of the tubes is the real thing the factory can put a sticker highlighting the tubes used and all the other tubes are regular straight gauge steel (good steel but straight gauge, cheaper too), this is a fact well known in the industry. But yes u can get a tube w/o any problems, just call Nova they for sure have tubing or can cut one for you.

    Good luck

    not sure what you mean by pre-tube. or did you mean PER tube? These level top tube 930's are pretty rare, Possibly though, the slant tubes in '93 were for the smaller sizes. It's a huge frame, but wicked stable. Dave thanks I appreciate it, I know you really do high end custom stuff . I might just keep riding it with the redneck weld.

    My bad - you know sometimes you spell something wrong but it ends up being a word anyway? Yes I meant $150 PER tube. That is the going rate from most anyone doing a repair like this.

    It seems you could ride the bike as it is until you can't and then have it repaired if you like. Options are good.

    Stay well,

    dave
