If a wheel or a chain breaks, it can be replaced with a regular bike wheel and regular bike chain.

一旦轮子或链条断裂，可用常规的自行车轮子或常规的自行车链条来替换。

I want to convince you guys to change your bicycles from one with a regular metal bike chain to a carbon fiber belt drive system.

我想说服你们把自行车从普通的金属自行车链条换成碳纤维皮带驱动系统。
