Which ratio should I be in? The lowest ratio on a NuVinci CVP is for the steepest hills. The highest ratio is for the greatest speed. Shifting from an easier, “slower” ratio to a harder “faster” ratio is called an upshift. Shifting from a harder, “faster” ratio to an easier, “slower” ratio is called a downshift. -

Rotate the CruiseController handgrip towards the rider until the shifter is in full overdrive and the inchworm is completely flat. - Page 15 While the cables are still routed through the pulley housing, begin to wrap cable A around the pulley, following the groove around the pulley. Wrap cable A around the pulley twice, making sure to keep the cable taught. Once the pulley is almost fully seated, without rotating it, pull the cables taught on the outside of the pulley housing.
- Page 16 Cable A is the shorter of the two cables, and is routed through the top cable guide of the rear pulley housing. The “dark” inner pulley is attached to cable A. With the hex bolt at the 12:00 o’clock position, install the dark lower pulley on the shift rod.
- Page 17 Pull the cable tight and use diagonal cutters to cut flush. Make sure there is no excess cable protruding below the silver upper pulley Begin to wrap cable B around the silver upper pulley, following the cable grooves on the pulley. Guide cable A through the bottom of the silver upper pulley.
