General Assembly Steps:
- Unpacking: Carefully remove all components from the packaging. Inspect for any shipping damage.
- Handlebar Installation: Attach the handlebar to the stem, ensuring it is centered and tightened securely.
- Front Wheel Installation: Install the front wheel into the fork dropouts. Ensure the quick-release skewer is properly installed and tightened. Verify disc brake alignment.
- Seat Post and Saddle: Insert the seat post into the frame and adjust the saddle height. Secure with the quick-release lever.
- Pedal Installation: Identify left (L) and right (R) pedals. Thread the pedals into the crank arms. Note that the left pedal has a reverse thread. Tighten firmly.
- Brake Adjustment: Ensure both front and rear disc brakes are properly aligned and functioning. Adjust cable tension if necessary.
- Gear Adjustment: Check and adjust front and rear derailleurs for smooth and accurate shifting across all 21 speeds.
- Tire Inflation: Inflate tires to the recommended pressure indicated on the tire sidewall.
- Final Check: Double-check all bolts, quick releases, and components for tightness and proper function before the first ride.

Operating Instructions
Gear Shifting (Shimano EF 500, Altus M310, Acera M3020):
Your bicycle is equipped with a 21-speed (3x7) Shimano gear system. Use the shifters on the handlebars to change gears.
- Right Shifter: Controls the rear derailleur (7 speeds). Use for fine-tuning speed and cadence. Shift to a lower gear (larger cog) for easier pedaling on inclines, and a higher gear (smaller cog) for faster speeds on flat or downhill terrain.
- Left Shifter: Controls the front derailleur (3 speeds). Use for larger changes in gearing, adapting to significant changes in terrain. Shift to a smaller chainring for climbing and a larger chainring for speed.
- Smooth Shifting: Always pedal lightly when shifting gears to avoid strain on the drivetrain components. Avoid shifting multiple gears at once, especially under heavy load.

Braking (JAK Dual Disc Brakes):
Your bike is equipped with powerful JAK dual disc brakes. The right lever controls the rear brake, and the left lever controls the front brake.
- Balanced Braking: Apply both brakes simultaneously for optimal stopping power and control.
- Front Brake: Provides significant stopping power but can cause the front wheel to lock up or lift the rear wheel if applied too aggressively.
- Rear Brake: Helps control speed and stability. Less powerful than the front brake.
- Wet Conditions: Disc brakes perform well in wet conditions, but stopping distances may increase. Apply brakes earlier and more gently.
Suspension Lockout (Alloy Zoom Masera Fork):
The front suspension fork features a lockout mechanism, allowing you to switch between a rigid and active suspension setup.
- Active Mode: For off-road trails and rough terrain, the suspension absorbs bumps for a smoother ride and improved traction.
- Locked Out Mode: For smooth roads or climbing, locking out the suspension prevents energy loss from fork compression, making pedaling more efficient.
- Operation: Refer to the specific lockout lever on your fork for engagement and disengagement. Do not force the lever.
Maintenance
Regular maintenance ensures the longevity and safe operation of your CRADIAC Alpha PRO GEN 2 bicycle.
Daily Checks:
- Tire Pressure: Check and maintain recommended tire pressure.
- Brakes: Ensure brakes engage firmly and release completely.
- Quick Releases: Verify all quick releases (wheels, seat post) are securely tightened.
Weekly/Bi-Weekly Checks:
- Chain Lubrication: Clean and lubricate the chain regularly, especially after riding in wet or dusty conditions.
- Cleaning: Wash your bike with mild soap and water. Avoid high-pressure washers directly on bearings.
- Bolt Tightness: Check and tighten all accessible bolts (stem, handlebars, crank arms, seat post clamp).
Monthly/Quarterly Checks:
- Brake Pads: Inspect brake pads for wear and replace if necessary.
- Gear Adjustment: Fine-tune gear shifting if it becomes imprecise.
- Wheel Trueness: Check wheels for wobbles or damage.
- Professional Service: Consider a professional tune-up at least once a year, or more frequently with heavy use.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Gears not shifting smoothly | Cable tension incorrect, dirty/dry chain, bent derailleur hanger | Adjust shifter cable tension, clean and lubricate chain, inspect derailleur hanger for damage. |
| Brakes feel spongy or weak | Cable stretch, worn brake pads, contaminated rotors | Adjust brake cable tension, replace worn brake pads, clean rotors with disc brake cleaner. |
| Tires lose air quickly | Puncture, faulty valve, improperly seated tire bead | Inspect tire for punctures and repair/replace tube, check valve stem, ensure tire is seated correctly on the rim. |
| Creaking noises while pedaling | Loose pedals, bottom bracket issues, loose crank arms | Tighten pedals, check crank arm bolts. If noise persists, professional inspection of bottom bracket may be needed. |
