How to Repair a Cannondale Bike
- 1). Inspect the cables running from the front and rear derailleurs. Look for abrasion or loose threads coming out of the rubber cable housing. If present, go to the barrel adjustments on the derailleur. Unscrew the barrel adjuster all the way to the left until the cable is loose and sloppy. Use the allen keys (5mm) to unscrew the derailleur cable housing and remove the cable.
- 2). Thread the new cable into the derailleur set screw and tighten with the 5mm allen key. Thread the cable up through the cable housings on the frame, leading to the shifter. Unscrew the cable set screw on the shifter pod and remove. Thread the new cable into the shifter pod set screw. Adjust the barrel adjusters on the shifter and the derailleur turning one quarter turn to the right until the cable is tight and the shifting is smooth. Ad a touch of bike grease to the ends of each cable.
- 3). Check the brakes for slop in the cable. If present, use the 5mm allen key to loosen the brake cable by turning to the left. Remove the cable and replace by threading the new cable into the set screws at the brake and tightening the set screws until the cable is firmly in place. Add a dollop of bike grease to the ends of each side of the brake cable.
- 4). Check the pedals for smooth movement in a 360-degree fashion. If sticky, add bike grease to the spool by unscrewing the pedal with the pedal wrench. Once the grease is added tighten the pedals onto the spool with the pedal wrench.
- 1). Unscrew the gasket cap on the top of the Cannondale Lefty, Headshock or other front suspension. Attach the pressure gauge to the air valve and check the air pressure in the suspension system. Cross reference this with the Cannondale user manual. Check what pressure setting the suspension should be set at for your weight. If low, attach the air pump to the suspension at the valve and add air until the suspension pressure equals Cannondale's recommendation for your weight.
- 2). Go to the rear suspension shock, found under the seat and near the rear triangle of the Cannondale bicycle frame. Cannondale uses Fox and RockShox rear suspension systems. Unscrew the top of the air valve and attach the pressure gauge to the shock.
- 3). Check the pressure and compare this to the Cannondale user manual's recommendations for your weight. If too low, attach the air pump and add air until the suspension pressure is equal to Cannondale's recommendations. If too high, pinch the air valve to bleed out air until the suspension is equal to Cannondale's recommendation.
- 1). Remove the front and rear wheels by turning the quick releases to the left until the wheels will come out. Place one wheel on a truing stand.
- 2). Slowly turn the wheel on the truing stand and check for bent or off-center spokes. The wheel will not go through the calipers evenly if there are spokes out of true. Locate the out-of-true spokes and use the spoke wrench to right them. Turn the spoke wrench to the right and watch the calipers. Once the wheel turns evenly in the truing stand the wheel is ready to go.
- 3). Remove wheel and replace on the bicycle. Place the second wheel into the truing stand and proceed as in step 2.
