    I have a differnet dream. My dream is a 2000 or so Santana Arriva frame modified to be a 650B low trail tandem modeled after classic French tandems. It is shown with Grand Bois 42mm tires and as pictured weighs 36.2 lbs including pedals, pump and rack. The weight should drop a little when the very long and heavy Santana seatpost used by the stoker is replaced. Trail is 39.2 mm.

    I am very pleased with both the speed, comfort and handling. After purchase of a donor frame the lateral tube was cut to test the ride of the bike as an open frame. Over the years I have decided that I enjoy more flexible singles and tandems. Keep in mind that I mean flexibility is a relative thing and with my stoker this bike has no wiggle when standing and handles around the tightest corners without a problem. It is not a flexible flyer, but is not as stiff as our Speedster or the original Arriva. We are a light 280 lb team with moderate power. I would estimate that with my wife as stoker this bike feels like captaining my Co-Motion Speedster with by 200 lb son as the stoker.

    Inspired by the results, the frame was then modified by Gallus Handmade Bicycles in Fort Worth, Texas. Below are pictures before, during and after the process of conversion. I already owned a steel fork from Bilenky in Philadelphia which has about 60 mm of rake and weighs about 1,000 grams.

    Wayne:
    By far the best-looking Santana we've seen . . . and without a lateral tube!!!
    Bill McC would shudder to think that anyone would "desecrate" his design!
    Hats off to Gallus for a fine job.

    This would pretty much sum it up:



    Cyfac has been great to work with. We pushed their creativity envelope a bit and it paid off. The bike handles like a dream, super stiff where it needs to be but comfortable over chip seal.

    Current setup is drop bars front & rear. I have the new lightning crank spyder here to put on, but have not had the motivation to disassemble it and install.

    How did you push their creativity envelope?
