建立自己的躺式自行车（十九）组装链管理系统Chain Management Overview 链管理概述 In earlier incarnations of the Zephyr, I employed a four chain pulley system for the chain management system. Although I heard all about the success of using Sprinkler Tubing for routing the chain, I thought the idea was crude and inefficient. As I studied the virtues of using sprinkler tubing, I became increasingly fond of the idea. 早在和风的化身，我雇用了4链管理系统滑轮系统的链条。链虽然我听到所有关于成功进行路由使用喷灌管，我认为我的想法是原油和效率不高。由于我学习的优点使用洒水管，我越来越喜欢的想法。 Eventually, I abandon using a four pulley chain system and resorted in using polypropylene tubing for routing the passive side of the chain. Not only did this prove to reduce the weight and complexity of the chain management system, it also kept the chain clean and prevented it from derailing from the pulleys. As for efficiency, the poly tube does produce extra drag on the chain. However, keeping the chain well lubed reduces this effect making it as competitive as the four pulley system. 最后，我放弃使用制度和四个滑轮链。不惜使用链聚丙烯管侧的路由被动的这不仅证明，以减少重量和系统复杂性的供应链管理，它也保持清洁，防止链条它从滑轮脱轨的。至于效率，聚管不产生额外阻力链上。然而，保持良好lubed链降低此影响决策系统滑轮的竞争能力，它的4个。
The illustration below summarizes the Thunderbolt chain management system. The system comprises of two chain pulleys (both forward and aft), two chain tube clamps, two 1/2' cable clamps, two mounting brackets (both forward and aft) and two polypropylene tubes (drive side and passive side). Of course this recipe is not complete without a handful of hardware and hard work. 下图总结了迅雷链管理系统。系统）包括两个链滑轮（包括前，后，二链管钳，两个1 / 2“电缆夹，两个安装支架（包括前，后）和两个塑料管（驱动器和被动方方）课程。本食谱是不完整的少数几个没有工作的硬件和努力。
