no cracks, but the rear part of the jaculus is way to rigid. Riding over anything but asphalt gives a headache because of the vibrations. I would use smaller tubing for the next one, saves weight and improves the ride. For the rear part of a (distant) future brother of the jaculus i was thinking of two straight tubes from eighter side of the rear axle to the sides of the pivot. These two should probably be connected just before the rear wheel (also brake mount) for the top support of the seat, and at the pivot.
