The Vivo Enduro was John L. Calendrille Jr.'s first design for a sealed derailleur. It sports his distinctive corrugated rubber 'boot'.
Like all of the Vivo derailleurs, it has no cable adjuster, but does have an grub screw to adjust the strength of the spring in the parallelogram. Some of its other features include:
- the cable feeds in from the rear of the derailleur.
- the cable inner is fed through a hole in the outer parallelogram plate and is clamped with a grub screw.
- the adjustment bolt at the b-pivot is a standard M5 Allen head bolt.
- the pulley wheels are aluminium sealed bearing units with 10 teeth.
- it is completely diassemblable, with removable parallelogram pivots.
- the whole feel is high-end-CNC-machined.
This example is anodised lurid red, has no logos and is stamped '001'. It is possibly a pre-production model.
