firmly away from the NuVinci CVP.

NuVinci Optimized CVPs are

incompatible with 1/8 inch (3.18mm)
single-speed chains and sprockets that
are flat on at least one side. Use 3/32 inch
(2.3mm) chains and sprockets only.

in interference with the Harmony
Hub Interface and damage to CVP
components and may result in a dangerous
condition for the rider.

(2.3mm) sprocket (B) with the flat side

The sprocket spacer is intended for
sprockets that are 3/32 inch (2.3mm) thick
at the inner diameter. If the inner diameter
is 0.17-0.18 inch (4.3-4.5mm) thick, the
spacer should not be used.
