Viewed from the third decade of the 21st century the 1937 Super Champion Route looks very modern. The pulley cage was long (at 90mm centre to centre), the guide pulley was massively offset, it was top-normal, the movement was horizontal - it was all very SRAM Eagle.

It was also the first non-fork-type Super Champion derailleur. There was still a bronze fork, but it didn't act on the chain - instead it acted on a pulley cage. This bronze pulley cage arm had cursive writing on it - very reminiscent of the chain tension arm of Super Champion's signature fork-type derailleur. The cable fitted with the nipple at derailleur end and the clamp bolt at the lever - all just like a Super Champion fork-type derailleur.

Unusually for Super Champion, it was very much a touring model. It is described in various catalogues as coming with a 3-speed freewheel and as having a, substantial, total capacity of 16 teeth.

I am aware of at least two types of Super Champion Route. The first had a chain tension spring that runs along the chainstay. The second had a chain tension spring that is integrated into the derailleur itself. I am not clear which of these two variants came first.

This is a typically well used example of the variant with the chain tension spring along the chainstay. Some of its key features are:

• The chain tension spring runs along the chainstay.
• The clamp bracket is for quite a small chainstay and includes a grub screw.
• The main operating spring is housed in aluminium shells.
• There is a 'chain catcher' at both pulleys, each of which is held in alignment by a cast-in, shaped, protrusion on the brass pulley cage.
• It has a round, unbranded tension pulley.
