    Unknown Rossin with a rattle can paint job

    Hello fellow BF'ers,

    See below for a mystery Rossin Frame I picked up a few years ago. Some of you may recognize these pictures from my C&V post. I had the intention of building it up, but alas other things got in the way. Now I'm planning on selling it.

    Any idea what this frame will fetch? I'm in a big market, Chicago, but I think ebay might be the way to go. Would waiting until the spring be a better idea? Any and all suggestions are appreciated. Thanks!

    I helped a mate restore a Rossin almost exactly like that. It is a good quality frame with a mixed bag of mid-high end components.
    He got the complete bike for under AUD100, because somebody had attacked it with house paint, and the seatpost is stuck. luckily, it is stuck at just the right height for him!

    When I bought it on ebay, it was listed as having SLX tubes, however I just checked for rifling and did not notice groove on the inside of the tubes. Given the campy DO's, internal housing, and what other members have suggested, I'm fairly confident it's Columbus SL.

    What size is it?
    It's a 56cm c-t-c.

    I'm considering getting it power coated, but I don't know if it'll be worth it. It'd love to see someone build it up.

    I've both heard that Columbus developed SLX to accommodate the braze-on front derailleur hanger, and a rebuttal of that "fact". But in general, SL frames will use clamp-on FD, those with FD b/o are SLX.

    That's very interesting Ex Pres. Do you have the source of where you read that? thanks!

    Here's a couple from here on BF. The same thread, though, had some disputing the claim.

I never liked braze on derailleurs until the investment cast fittings were in use and SLX was used. SL flexed way too much and changed derailleur performance in a way I did not like, there was a noticeable reduction in flex of the tube as one shifted the bike on the work stand with SLX.

There was an SLX seat tube only, for a short period before Columbus decided to apply the technology to the down tube and seat stays and release the SLX tubeset. The spiral reinforcements extend 150mm (6") from the bottom of the seat tube, so they extend slightly beyond the top of the typical braze-on position, unless the builder removes the excess material from the wrong end when sizing the seat tube.
    Of course, if your frame pre-dates SLX, then this info doesn't apply.

    Thanks for the follow though. I think the frame predates SLX tubes, though I'm really not sure.
