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. 184g 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 an earlier model - but I have no evidence for this beyond my (faulty) memory. I can still, just about, name Gordon Banks, Nobby Stiles, Jack Charlton, Bobby Moore, Bobby Charlton, Alan Ball, Martin Peters and Geoff Hurst. But if I have already forgotten the other three, what chance has a Rino Crono?
