This comprehensive Trade Catalogue features the MAVIC 840, MAVIC 841 and a prototype of the MAVIC 845.

The versions of MAVIC 840 and MAVIC 841 shown are the familiar versions, with a conventional allen key hanger bolt and dropout adjuster.

However, the version of the MAVIC 845 shown is one that I have never seen in the flesh. It attaches to the dropout hanger using an allen key screwed in from the inside and has an extravantly shaped pulley cage - using a design registered by Simplex.

This dropout attachment system can be seen on the MAVIC 840 prototype in this collection. Perhaps one day I will see a MAVIC 845 that also has it.
