Aftercare Guidance for Your New Bike

Congratulations on your new bicycle! To ensure it performs optimally and lasts for years, proper aftercare is essential. Here's a guide to help you maintain your bike:

Initial Check-Up (First 50-100 miles)

• Gear Adjustment: It is to be expected that new cable operated gear systems will require resetting after the first few rides due to cable stretch. We would recommend this i done by a qualified Cycle Mechanic as gear adjustment is not easy for the novice. It will ensure smooth gear shifting and avoid damage.
• Brake Adjustment: After your first few rides, check the brakes for any wear or adjustment needs.
• Wheel Truing: Inspect your wheels for any wobbles. If you notice any, take your bike to a professional for truing.
• Lubrication: Apply chain oil to prevent rust and ensure smooth shifting. Wipe off any excess to avoid dirt accumulation.
• Tightening: Tighten bolts on your frame, handlebars, seat, and pedals to ensure everything is secure.
• Tyre Pressure: Check tire pressure regularly to avoid flats and ensure a smooth ride.

Routine Maintenance (Every Few Weeks)

• Chain Care: Clean and lubricate the chain regularly to prevent wear and maintain smooth gear shifting.
• Brake Safety: Before each ride, always pull hard on the brake levers to ensure they are functioning properly. If the brake levers pull too close to the handlebars, this could indicate that the brake pads are worn or that servicing is needed. Regularly check the brake pads for wear and replace them if they are heavily worn. If your hydraulic brakes feel spongy, they may need to be bled to restore proper function. This should be done by an authorized dealer or a qualified mechanic. Keep the braking surfaces clean and free of oil or grease, as contamination can reduce braking efficiency and pose a safety risk. Maintaining your brakes in good condition is critical for safe riding, so be sure to inspect them regularly and address any issues promptly.
• Tyre Inspection: Check tyres for punctures, cracks, or excessive wear. Maintain the correct air pressure to avoid premature wear. Check tyre pressure, ensuring it matches the recommended levels indicated on the sidewall. Failure to do so can impair performance and increase the risk of failure or personal injury
• Handlebar and Stem Safety: It's essential to regularly check the alignment of your handlebars and stem. Ensure that the handlebars are positioned at a 90-degree angle to the front of the bike and that the clamping bolts are tightly secured. This will prevent the bars from twisting while riding. Failure to properly align and tighten the handlebars and stem can lead to a loss of control, potential bike damage, and risk of personal injury. Always follow the manufacturer's instructions and check these components before each ride for your safety.
• Nuts and bolts: Tighten any loose parts to prevent accidents, check regularly. Some will require setting with a torque wrench in line with manufacturer instructions. Repetitive loosening of a component may indicate an underlying problem requiring a qualified Bike Mechanic for Guidance.
• Wheels and Seat Pins: Ensure that wheels and seat pins are securely tightened and properly closed before every ride. Follow the manufacturer's instructions to prevent any issues while cycling. Proper maintenance keeps your bike safe and reliable.
• Forks and Rear Shocks: Ensure that the forks and rear shocks are correctly inflated and preloaded according to your rider weight. This will help maximize efficiency and comfort while riding. Regularly check the suspension pivots for tightness and signs of wear. Loose or worn pivots can lead to damage and compromise the performance of your bike, potentially causing injury. To prolong the life of your suspension seals and stanchions, make sure they are kept clear of mud, dirt, and debris. Build-up can damage the suspension system and reduce its effectiveness. By keeping your suspension well-maintained, you'll ensure a smoother, safer ride and help extend the life of your bike.
• Frame Safety Check: Regularly inspect your bike frame for any signs of damage, cracks, or stress points. A compromised frame can lead to serious safety issues, including loss of control or breakage while riding. Look closely for any cracks, dents, or deep scratches on the frame, particularly around high-stress areas like the bottom bracket, head tube, and chainstay. Pay extra attention to areas where the frame may flex or be under pressure, as these spots are more prone to developing cracks. Inspect the welds and joints for any signs of fatigue or separation. If you notice any irregularities, consult a professional mechanic immediately.
• Clean the Bike: Regularly clean your bike using a soft cloth and mild detergent. Avoid using harsh chemicals or high-pressure water.

Seasonal Maintenance

• Gear Check: Inspect the drivetrain for any issues, like slipping gears or noise. Clean and lubricate the cassette, chain, and derailleurs.
• Suspension: If your bike has suspension, check the forks and shocks for proper performance and adjust or service them as needed.
• Wheel Condition: Check for wear on the rims and spokes. Ensure they are properly tensioned to avoid wheel failure.
• Frame Inspection: Examine the frame for cracks or damage, especially after a fall or rough riding conditions.
• Store Indoors: Store your bike in a dry place to protect it from extreme weather conditions like rain, snow, or direct sunlight, which can cause rust or fade paint.

Regular Professional Check-Ups

• Road Bikes: For optimal performance, aim to service your road bike every 100 hours of riding.
• Mountain Bikes: If you ride a mountain bike, it’s recommended to service it every 50 hours of riding due to the more demanding conditions.

Regular servicing helps maintain the health of key components, such as the drivetrain, suspension, and brakes, ensuring your bike stays in top condition and safe to ride. Always follow the service intervals that best match your riding style and consult a professional mechanic if you’re unsure about when to bring your bike in for maintenance.
