Bottom Bracket for OPC

One-piece crank bottom bracket is one of the most important products among the four self-manufacturered by SUMLON‘s factory. We have been making and selling bottom brackets for OPC over 15 years. The products are sold to major markets such as the United States, Europe, Japan, and South Korea. The main buyers include Walmart, Giant, and other retailers and bicycle manufacturers. Relatively lower prices and higher quality are prerequisites for survival in this market. You can count on that. If you are looking for a one-piece crank bottom bracket manufacturer, we’ll be the the very best choice.

In 2022, SUMLON decided to directly offer factory wholesale to potential buyers to minimize your costs. Our one-piece crank bottom bracket cup set will be shipped directly from our factory. SUMLON is located in the distribution center of China’s bicycle parts industry, which is very close to the shipping port. If the inventory level is average, we can start shipping within two weeks after the order is placed.
