LockR

To remove the LockR from the frame:

1. Loosen the screw 4-6 turns using a T25 Torx key.

2. Tap head of screw with a rubber mallet to un-seat the wedge bolt located on the opposite side.
3. Remove the screw and wedge bolt from the still-installed axle.
4. If the wedge did not come out with the screw, insert a 5 mm hex key and turn to free and remove
it. If wedge still sticks, insert a wooden or plastic dowel into the drive side and drive it out.
5. To remove the axle itself, insert a 6 mm hex key into the axle on the non-drive side and turn
counter-clockwise until it can be removed.

To install the LockR on the frame:

1. Disassemble and clean all parts of the LockR axle. Do not install it assembled.
Inspect the parts for damage (e.g., burrs, scratches, deformity, wear). Replace the entire LockR
assembly if any damage is found.
2. Apply a light coating of a high-quality bicycle bearing grease to all parts. No grease on axle
surfaces that mate with the IGUS bearings (bushings)
3. Align the linkage and bearing and insert the threaded end of the pivot axle (1) in from the non-
drive side.
4. From the non-drive side, tighten the inserted pivot axle to 1 Nm using a 6mm hex key fitted to a
torque wrench.
5. Insert the wedge bolt (2) into the drive side of the axle and insert the small end of the wedge (3)
into the non-drive side axle head.
6. Thread the screw (4) into the wedge bolt with a wrench and tighten to 5.0 Nm.

NOTICE
Use a calibrated torque wrench. Exceeding 1 N·m will result in permanent damage to the
LockR pivot system.
Bushings:

The pivot axle should slide and rotate smoothly in the bushings. Remove bushings (5)
only if damaged or when excessive axle play is detected. Always install bushings as a new
set following removal. Do not re-use bushings. Remove and install bushing using the
bushing tool. See Replacement Parts.

SmartSense
As an option, this frame supports installation of a Cannondale SmartSense system, an intelligent
communication network and power source. This manual describes only the technical details
specific to the frame such as component locations, installation, and related service information.

What is SmartSense?
SmartSense is a system of interconnected or networked powered accessories. Each networked
accessory shares the same data communication and same rechargeable battery. The behavior of
each accessory can be programmed and controlled independently or coordinated with any other
component.

SmartSense System Components

A SmartSense system can consist of variety of components. For example:

• Garmin Varia Core cradle

• Garmin Varia Core battery

• Garmin Varia Radar sensing unit

• Garmin Varia Radar Display Unit

• Garmin Cycling Computers

• Cannondale Foresite e350 front light

• Cannondale Hindsite Array rear light

• Internally routed communication/power cables

downtube opening. Either part should remain in place to prevent dirt, dust, or water from
entering the inside of the frame.

• Remove the SmartSense cradle from the frame in order to connect or to disconnect the
internal extension cables. It is not possible to service these cables with the cradle in place.
