Athletes should wipe down their bikes every day. Through regular cleaning, not only can the bicycle be kept clean and presentable, but it also helps inspect the condition of all parts, fostering a sense of responsibility and dedication in athletes.
When inspecting the bike, pay attention to the following: there should be no cracks or deformations on the frame, fork, or other parts; all screws must be tightly secured, and the handlebars should turn smoothly. Inspect each link of the chain carefully—remove cracked links and replace broken ones to ensure normal chain operation. Avoid changing to a new chain during competitions to prevent mismatch with old gears that could cause chain drops. If replacement is necessary, change both the chain and the freewheel together. The braking system should have all components intact, with proper clearance between the brake pads and the rim, ensuring sensitive and effective braking. The freewheel and derailleur should work in harmony, allowing smooth gear shifts across all settings, with fast transmission and moderate spring tension, and the shift cables should be smooth and unobstructed. After each training session or race, return all derailleur components to their neutral positions to reduce spring pressure and extend the life of the derailleur. Check that all bearing parts rotate smoothly without damage, paying special attention to tightening the right middle axle screw. Shoe covers, straps, and pedals should be intact. The saddle should remain parallel to the top tube, not tilted, positioned correctly front to back. If the saddle cover is damaged, replace it immediately. The wheels should be properly aligned; any tilt or deformation may cause the wheels to bounce up and down or sway side to side, requiring realignment. Proper lubrication of the bicycle is essential.
The relative motion between bicycle components involves rolling and sliding movements. Bearing areas produce rolling friction, while the chain, chainrings, freewheel, and other moving parts generate sliding friction. To reduce friction during movement, lubricant should be applied regularly to transform direct friction between parts into friction with the lubricant. This prevents direct contact between components, turning dry friction into wet friction and reducing frictional resistance. This results in smoother, lighter riding and conserves energy. Wet friction generates only one-fortieth of the resistance of dry friction. As a result, wet friction produces less heat, preventing parts from overheating and deforming, reducing wear, and protecting the components. This is especially important during training and competitions in rainy conditions, when extra care should be taken to apply lubricant to prevent component failure or damage due to moisture. Therefore, every cyclist should pay close attention to the use of lubricants.
Use lubricants in moderation. Apply less on sunny days, as excessive lubrication can attract dust and affect rotation. Apply more on rainy days (especially on the chain). For multi-day races, it’s best to carry a small oil bottle and apply lubricant to the chain every two hours of riding to reduce friction. Otherwise, normal chain transmission may be compromised, increasing physical exertion.
