    Old bikes need love, too.
    Just before Christmas I took this 1976 Bill Boston to The Barn to have some modifications and a new paint job. It was great to meet and talk to the man himself, and getting it back will feel like getting a new bike!

    Big!

    I'm 6'2 with a 36" inseam. When I had this bike built at age 20, I weighed about 200 lbs - I weigh a good bit more now, but not as much as a year ago. My primary reason for going custom was not being able to find a stock frame, way back then, that fit me. From what I see of modern bike makers, not much has changed.
    On the other hand, if this was a Rivendell it would have three top tubes.

    My sprectrum was the most beautiful bike I owned (except maybe my custom in the works)

    amazing craftsmanship!

    Recent delivery to the Bay area. This one is clearly being used properly. First ride stopped off for coffee. By the way, that color is the official Pepsi Blue from their '89 add campaign. Lettering is School Bus Yellow.

    Fitting 32mm tires on a pair of Velocity A23s can work just fine on a spritely bike fitted with Dura-Ace 9000. Cool.

    Tom how does anyone choose between your steel and ti bikes? I keep vacilating on my fantasy frame.

    Honestly, in most cases it comes down to what a client wants. Yeah, that is no answer, but it seems to be the answer for most folks. In a number of cases, a client will already have one of our bikes and they will decide to get one made out the "other" material as well. In other cases they have simply had a hankering for one of our frames for a long time and they have simply have a vision in their heads of what they want. You are in a bad place because you don't know for sure what you want. Not that it will be much help, but here are a few thoughts;

    - Our steel frame look better to most people than our Ti frames. They are skinnier and they have lugs. Ti frames can look kind of boring unless they are painted in some cool way.
    - Ti frames are almost always lighter. The average difference in weight between a steel and Ti frame depends on frame size and intended purpose, ranging from a bit less than a pound to well over two pounds.
    - Longevity ... toss up.
    - Ride quality ... both materials offer a lively "metal" ride when designed and built properly. In fact, the two materials can build remarkably similar riding bikes. On longer rides, like over three and a half hours, Ti offers a ride that will leave you feeling fresher, especially in your upper body, than any other material. So if your rides are usually under three hours, ride differences just don't matter.

    Not much help, I know. The problem is that both materials work so well. Sorry.

    Woah! So no need for mid/long-reach brakes now? Fully inflated tire clear for in and out?

    Sweet looking frame too.

    Depends on the calipers. The ones in the picture are the Dura-Ace 9000 calipers which have an unusually effective QR. It is a little hard to see in the picture, but we designed the fork so that the pads are almost all of the way down the slots when set up properly. The New Red calipers have similar capability.

    With that setup, what is the distance between the pads and the brake caliper bolt?

    In theory, it should be about 47.5 but it is never that simple. We did set up the fork span so that we would be 1.5mm short of full extension. With the James crown we used and an offset of 45mm, the span was 367.5mm. Helps?

    367.5 to brake mount hole? I just built a fork to accommodate 24mm wide rims and 27c tires mated to the older Red calipers so I was comparing notes.

    No, No, No. Span is measured from axle center to crown race seat parallel to the steerer tube. Drawing attached below. As long as your crown top to brake hole measurement is consistent, this will work with other crowns, just.

    A few shots of a recent Ti coupled frame set.

    Yes, that is pearl candy pink lettering. It appears on the inside of the fork blades as well. Our clients have great taste.

    Working with a 9000 FD? Chain ring sizes? Might be a solution for a puzzle I'm working on.

    Sure. The Carmina allows you to do almost anything. Single, double, triple, any bolt circle(s), any ring thickness, etc. Do their rings shift quite as well as DA9000? Not quite, but the front derailleur is so good that it works just fine. Hope this helps.
