來個爆炸性的--什麼輪子跑得快？

Tech feature: The work of Wheel Energy from Cyclingnews

我只摘取重點

1. Wider tyres roll faster than narrower ones--肥胎比較快

2. Larger diameter wheels roll faster than smaller ones--大輪比較快

3. Higher thread counts aren't always better--高tpi也不一定好

4. Puncture-resistant belts work but they're not created equal--防穿刺層有效，但效果未必都一樣

5. Tread pattern matters, even on the road--胎紋是有用的，光頭胎不一定是抓地力最好的

6. Latex tubes roll faster than butyl tubes--杜蕾斯乳膠內胎比較快

文中也順道提出，Wheel Energy對於騎士能感覺滾動差異的最小極限為5％
