WARNINGThis supplement may include procedures beyond the scope of general mechanical aptitude. Special tools, skills, and knowledge may be required. Improper mechanical work increases the risk of an accident. Any bicycle accident has risk of serious injury, paralysis or death. To minimize risk we strongly recommend that owners always have mechanical work done by an authorized Cannondale retailer.

5. Threads tool part 1 into spindle until the top of the stud is flush with the top of the spindle.
6. Install the tool body into the crankarm completely and tighten it snug with a 15mm open end wrench.
6. Install tool part 2 into the crankarm completely and tighten it snug with a 15mm open end wrench.
7. Insert a 8mm Allen key through the tool part 2 and into part 1. Hold the crankarm and turn the Allen key counter-clockwise until the crankarm can be removed from the spindle end.
8. Repeat the previous steps for the other crankarm.

Crankarm Installation1. Clean the spindle end, spindle threads,
crankarm socket and apply a high-quality bicycle bearing grease.
2. Align the splines and install the crankarm onto the spindle end.
3. Apply grease to the bolt threads and thin steel washer. Install the thin steel washer and fixing bolt into the crankarm and carefully thread into the spindle.
4. Tighten the fixing bolt to 34-41Nm using a torque wrench.
5. Repeat the process above for the other crankarm.

6. Install the seal *(1), bearing shield (2), spacers* (3), shims (4) and wave washer (5) onto the drive side spindle end.
NOTE: Up to 5 of the .5mm shims can be used. The total number of shims depends on the compression state of the wave washer with the crankarm installed and tightened to the recommended torque. The wave washer should appear “compressed but not flattened.”

Spindle Removal1. Remove the drive side crankarm.
2. Remove the small parts from the drive side spindle end (wave washer, shims, spacer (mountain only) bearing shield and seal (mountain only).
3. On the drive spide, tap the spindle end to drive it out the non-drive side. Pull it out on the non-drive side with your hand.
NOTE: Use a dowel (PVC shown) on the spindle end once it is inside the shell to continue driving the spindle out.
CAUTIONUse only rubber mallet.
�
Bearing Inspection1. Remove the crankarms and spindle from
the bottom bracket shell.
2. Rotate the inner bearing race of both bearings; rotation should be smooth quietly. No bearing play or movement inside the shell. If the bearing is damaged, replace both bearings with new ones.
Bearing RemovalFrequent or routine renewal of undamaged bearings is not recommended. Repeated removal and reinstallation can damage the inside BB shell surfaces resulting in poor bearing fit.
1. To remove the bearings, position Cannondale tool KT011/ behind the bearing so that the tool ridges are seated on the bearing.
2. Insert a driver (punch or drift) from the opposite side. Locate it on the back of the tool and use light tapping to drive the bearing from the shell.

Bearing Installation1. Clean the inside and outside surfaces of
the bottom bracket shell..
2. Apply a high-quality bicycle bearing grease to the inside surface of the shell.
3. Install the square end of the circlip into the groove first, then moving clockwise, push the clip into the groove until it is fully seated in the groove. Install the other circlip the same way.
4. With a headset press, and tool KT010/ install the bearings into the shell as shown. Press the bearing until it is seated against the circlip.
5. To finish, apply a light coating of a high-quality bicycle bearing grease to both sides of each bearing to help repel moisture.
NOTE: Circlip removal is unnecessary for bearing replacement unless the circlip is damaged. damage is present. A damaged circlip can be removed by using a small thin-blade screw driver to lift the hooked end up out of the groove and then pushing the circlip out counter-clockwise.
WARNINGSHARP EDGES. Circlips can have sharp edges. Wear hand protection.
CAUTIONDo not face, mill or machine the BB30 bottom bracket shell .

BB30-to-Standard English Thread Adapter The SI bottom bracket adapter enables the use of standard English/68mm or 73mm bottom bracket cranksets in Cannondale System Integration (SI) road or mountain bicycle frames.
WARNINGSERIOUS FRAME DAMAGE
On bicycle frames with carbon fiber BB shells, once installed the adapter is a non-removable/ permanent frame part. Do not remove it. Adapters must be installed by a professional bike mechanic.
NOTE: The adapter IS NOT a frame repair part and will only work in undamaged frames in good condition. Improper installation or removal can result in damage and void applicable frame warranty.
Installation
1. Remove bearings and circlips from BB shell.
2. Clean inside of the bottom bracket shell. Remove all grease. Do not use abrasives.
3. Apply Loctite 609 to the BB shell bearing seat surfaces ensuring complete coverage and install the ADAPTER with the groove on the drive side using a headset bearing press and the installation tool. Press the ADAPTER until the groove side face is flush with the drive side face of the SI BB shell.
4. Allow at least 12 hours (at 72°F) for the Loctite to cure before installing the standard bottom bracket crankset. Follow manufacturer’s instructions. Loctite Technical Data Sheet http://tds.loctite.com/tds5/docs/609-EN.PDF
RemovalThe adapter is removable only on alloy BB frames, however, repeated removal and reinstallation could result in damage to the SI BB shell and is not recommended.
1. Removal with extraction tool KF366/ , a two-piece tool set used with a headset bearing press. The arrangement of the tool parts for removal is shown next figure.
2. Following removal, clean all remaining Loctite residue with a before reinstalling the SI circlips and bearings. Use Loctite 768. Use a dental pick to remove any adhesive from the grooves. Do not cut, face, or use abrasives to clean the inside if the BB shell.
