A pleasant (if slightly roughly finished) melange of the SunTour Vx, SunTour Superbe and the SunTour Cyclone. The cable clamp arrangement is pure Vx, but Rino have managed to incorporate some of the curved muscular look of the Superbe by rounding off the Vx’s sharp corners and using the Superbe’s outer cable stop. The black paint harks back to the SunTour Cyclone. It’s a family affair!
In common with other Rino gears the parallelogram pivots have screw threads and slotted heads - so it is possible that the derailleur is fully demountable - but I have not tried it.
Rino have worked some magic on the weight, using aluminium for some of the larger bolts. 177g is seriously light - and this was probably the best-changing derailleur that was manufactured anywhere in Europe at the time.
I think this example is a later model - but I have no evidence for this beyond my (faulty) memory. I can still, just about, recall the details of the E Type Jaguar, the Rover 3.5 Coupé and the hapless Triumph Vitesse. But if I have already forgotten most that I ever knew about the Marcos GT, the Alvis TE21 and the Gordon Keeble, what chance has a Rino Crono?
