    May I get a second eye on these numbers?

    This is the first frame I've built for someone else.
    May I get a second opinion on my geometry?
    It's going to be used for centuries/brevets and the like.

    Bamboo main triangle

    Seat tube angle: 73.5
    Fork rake: 45 mm
    Bottom Bracket drop: 80 mm

    Rider's measurements:
    Inseam: 31.5 inches

    Thanks Dazza.

    Are my numbers that far off? Damn.
    It's not a sale, it's a gift for a close friend who knows I'm an amateur.

    But to answer your question, no I don't.
    Before I would even consider hanging out a shingle I want at least a dozen frames on the road, 5k+ miles on a few, and a couple professionally tested to destruction. Putting someone's health at risk is not something I take lightly.

    Are you sure the height measurement is right?

    I miss typed, I have it marked as 31 inches in my drawings.
    And since I haven't cut any tubes yet I think I'll start over.
