Bicycle Parts
As bicycles become more and more popular, their construction and accessories are becoming better known. Some of the Bike parts require regular maintenance or replacement, such as the chain and brake panels. Proper chain tension is essential for efficient power transfer from the pedals to the rear wheel. If the chain is too loose, it can lead to slippage and loss of power. If it is too tight, it will cause unnecessary friction and wear on the chain and bike freewheel. The chain tensioner is a key component in maintaining the correct tension in your bike's chain. It ensures that the chain runs smoothly and does not slip or jump off the sprocket. And the bottom bracket is the central component that holds the crankset (the pedals and gears) in place and allows it to rotate. A well-functioning bottom bracket is vital for a smooth and efficient ride. If the bottom bracket is worn or damaged, even rainy riding causes seepage, it can cause friction, creaking noises, and even prevent the crankset from rotating properly. So it's important to check the bike status in time to ensure safe riding. We have almost all the parts for the whole bike, the bike stem in alloy, the seat post in multi-size and so on.
