• See section 8.1 (for chainline and beltline
specifications).
• The NuVinci Optimized CVPs are
compatible with 16 to 28 tooth sprockets.
See section 8.1 for sprocket ratio
requirements and approved gearing.
3. If a Harmony Hub Interface is not installed
immediately following the sprocket, replace
the anti-shift retainer (A).
6.2 Installing the Sprocket
1. Remove the anti-shift retainer (A) by pulling
firmly away from the NuVinci CVP.
2. Install a standard 9-spline 3/32 inch
(2.3mm) sprocket (B) with the flat side
facing the CVP, followed by the supplied
sprocket spacer (C, if required), and secure
with the sprocket snap ring (D).
• 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.

Use of incompatible chains can result
in interference with the Harmony
Hub Interface and damage to CVP
components and may result in a dangerous
condition for the rider.
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.
If the sprocket is asymmetric,
incorrect installation can result in
interference with the Harmony Hub
Interface and damage to CVP components
and may result in a dangerous condition for
the rider.
