In its early stage, PROX focused primarily on carbon Road rims. 2016 - Carbon fat bike rims and BMX rims were added to our product portfolio. 2017 - Our product range expanded further to include MTB and e-MTB carbon rims. 2018 - We established wheel-building workshop and began in-house assembly of complete carbon wheels. 2019 – LightCarbon (China leading carbon frame manufacturer) invested in PROX, forming a strategic partnership. PROX focuses on carbon rims and wheels, while LightCarbon focuses on carbon frameset. Since then, both PROX and LightCarbon are able to supply carbon rims, carbon wheels and carbon frameset, with same factory price. So it is convenient for customers to do one-stop purchasing from either team.   In 2023, Carbon gravel rims were officially introduced, further strengthening PROX’s product range. Today, PROX continues to refine rim designs, optimize manufacturing processes, and expand OEM/ODM cooperation with bicycle brands worldwide.  Why Choose PROX?
