    McMahon ti road frame

    I just bought a McMahon ti road bike frame that has a Kestrel EMS fork. I am trying to work out the year it was built so I can adorn it with the correct components.

    The serial number means nothing to me: M58005

    So I believe the only way I can estimate its age is by the fork, assuming its the original fork that came with the frame? Its 1 inch threaded.

    Any ideas anyone?

    Mid to late 90s? The fork looks like the steerer has been cut too short to even mount a stem.

    I agree, about mid-1990s. The builder was Steve McMahon out of Carpinteria, California.

    Yeah my buddy ended up in hospital as the suspension fork did not rebound. His tire ended up hitting the brake arch. Ouch.

    Because I was in the market for a ti frame in late 1993 and I even considered the McMahon. I ordered Litespeed Classic instead. The Litespeeds had horizontal dropouts while the McMahon had vertical drops. But on second thought, it could be a model from a year or two later....

    Ah, you appear correct--I couldn't tell if there were threads. Period-wise that would make sense.

    My memory is a little foggy but I don't think McMahon made these frames themselves. The dropouts don't look like Litespeed but they did play around some in those days so maybe. Regarding age, my guess is early '90's.

    You're correct Nessism, they were welded by Sandvik, AFAIK.
