    Spectrum 4130 Chain Stays

    Material: 4130 @ 740-850 MPa
    Length: 490mm
    22.2mm section length: 200mm
    Large end gauge: 0.85mm
    Small end diameter: 13.2mm
    Small end gauge: 0.9mm
    Straightness: +-1.2mm
    Price, Sold in pairs: 24.50

    Our new shipment of chain stays are ready for delivery. With this order from Reynolds, we have tweaked the design to give builders even more design flexibility than ever before. Not only does the new stay offer builders a much wider range of stiffness adjustability than any other chain stays on the market, but it is considerably lighter than all but the most flexible stays available. Working with Reynolds, we were able to start the swaging process with a thinner taper gauge then other mills use, giving us a final small end gauge which meets the specification of a single taper gauge. In most other cases, builders are stuck with extra thickness and weight where they don't want it and less stiffness where they need it most. We considered ordering the stays in 531 material because of its excellent notch hardness properties, but the weldability of the material would have suffered.

    I've been silent on here for a LOOOOOONG time. It's as simple as ... too much work, and a worry that posting more pictures just gets us more orders. Something we really haven't needed. But I've been getting complaints as well. For some reason, there are some folks who want to see what we've been up to. So here are a few shots of the batch I just finished up Thursday around noon. I have been sick with the coughing thing that everyone seems to have and I couldn't get to the final clear coats until Then. If I remember, I'll take some more shots of the bikes when they are all built up in another week. Let's see; one will be E-Tap, another Ultegra Di2 Hydro, a third D-A mechanical and another is to be Chorus mechanical. Nice range. Here you go.

    As always your painting skills are world class. I know this question has been asked earlier but it seems that you are building a lot more Ti frames than steel. What is your current ratio of Ti vs steel? I also truly enjoy the build process on your website of Jeff's steel frames from start to finish. Is it possible Tom to show at start to finish a Ti frame being build by Seven? I will be ordering a Spectrum very soon but I am still 50/50 between the two materials.

    Cool:
    Thanks for the compliment. We are moving more titanium through here than steel, about in a five to three ratio. It just turned out with this paint batch there were a lot more ti frames than steel. The paint batch I am about to start will have three new steel frames, two new ti frames and two refinish jobs. I paint in batches of seven simply because in the two areas where the process work hangs, there are seven hooks and seven pegs. The other reason is that finishing more than about seven at a time is just too hard. When it comes to the final sanding stage, each frame takes me about an hour and a half to sand in preparation for the final two clear coats. More than seven frames would pretty much kill me. My fingers get kind of bruised after about five hours of sanding. And then there is my brain which pretty much turns to mush after about three hours of that stuff.

    I don't know if Seven has ever done a series of build photos or some sort of video of the basic steps that go into fabricating a titanium frame. Your best bet is to try getting in touch with them for that.

    I had thought of creating some sort of time-lapse video of the frame drawing process. I am not a trained draftsman, but I'm told that the drawings I create for ABG and Seven are actually pretty good. I am proud of them and it might be fun to so some sort of video of the process. A single drawing generally takes me about two hours to finish, but I would try to squash it down into about two minutes. Might be fun.

    One of these is mine--Chorus mechanical (the light blue with the classic white panels). Tom, that paint is amazing, and I can't wait to see it in person!

    Tom,

    I stopped by Firth and Wilson Transportation Cycles on Saturday with a bent fork. While Simon was straightening it for me, I spotted a Bill Boston tandem hanging in the rafters waiting for some attention. He was going to convert to 650B. Looked fantastic. Did your time with Bill include any tandem work?

    The short answer is "yes." I worked for Bill during the summer of '76 and during that time he did build a tandem. Honestly, I don't even remember for sure the color or who it was for. For some reason though, I think it may have been for a lovely Quaker couple from the Philadelphia area. Funny the things you remember after all these years.
