45NRTH 採用兩件式結構設計,打造可靠且高性能的自行車輪胎防滑釘,具有凹形碳化鋁設計。超大尺寸的凹形冠部形成開放空間和碗狀內緣,使表面積增加兩倍,進而提升牽引力和抓地力。
- 以 100 入包裝販售
- XL 款採用更大的碳化鎢尖端直徑,適用於極端冬季騎乘。我們不建議將此產品用於電動輔助自行車,因為額外的扭力和系統重量可能導致外胎過早磨損和防滑釘脫落。
- We design 45NRTH tires for extreme winter cycling applications. We do not recommend this product be used with power assist bikes as the additional torque and system weight can lead to pre-mature casing wear and stud loss.
