Dedicated cyclists spend hundreds of hours each year on their bikes. The need for lightweight and high-performance bikes is justified, as is the desire for comfort. Vibrations generated by defects in the road surface are a significant source of discomfort, fatigue and disincentive to ride, therefore the capability to filter these vibrations is paramount. Our research objective is to improve dynamic comfort, which we define as reducing the level of vibratory discomfort. Designing a road bike with comfort in mind is a major challenge, because contrary to other types of bicycles (i.e. mountain bikes), road bikes have no suspension system: isolation from vibrations therefore depends mainly on the dynamic behaviour of bike components.

专业自行车手每年花费数百小时骑自行车。对轻质和高性能自行车的需求是合理的，对舒适性的渴望也是合理的。路面缺陷产生的振动是造成不适、疲劳和阻碍骑行的重要原因，因此过滤这些振动的能力至关重要。我们的研究目标是提高动态舒适度，我们将其定义为降低振动不适程度。设计一款兼顾舒适性的公路自行车是一项重大挑战，因为与其他类型的自行车（即山地自行车）相反，公路自行车没有悬架系统：因此，振动隔离主要取决于自行车部件的动态行为。
