    • Embodiments described herein provide for one or more of: (1) airflow enhancement around a rim using cusps that create virtual surfaces of air with the bike in motion, which also encourage favorable air attachment around the rim; (2) wake reduction by streamlining the airfoil around the rim using trip edges at various points of rim surface transition, which cause a laminar flow to go turbulent for enhancing the streamline effect; (3) a double rim surface, which provides an air slot between the two rim surfaces at a distance that enhances flow attachment and adds energy of air flow around the rim by moving air between areas of high and low pressure; and (4) a tubeless tire rim kit capable of converting conventional rims into tubeless ones and also promoting the sealing of the tire to the rim with minimal air pressure necessary to create the seal.
    • 本文描述的实施例提供以下一个或多个:(1)围绕边缘的气流增强,其使用在自行车运动中产生空气的虚拟表面的尖端,这也促进围绕边缘的有利的空气附着; (2)通过在边缘表面过渡的各个点处的跳闸边缘来简化边缘周围的翼型而引起尾流减少,这导致层流湍流以增强流线效应; (3)双边缘表面,其在两个边缘表面之间提供一个空气狭槽,该距离增强流动附着,并通过在高低压区域之间移动空气来增加围绕边缘的气流的能量; 和(4)无内胎轮胎护套套件,其能够将传统的轮圈转换成无内胎轮圈套件,并且还可以以最小的空气压力促进轮胎密封到轮辋,从而产生密封。
