不要被廠商騙了,我們要獨立思考。
現在的碟煞Tubeless胎絕不是最佳解!!!
公路車的競速極致絕對是管胎框煞。
以管胎,Clincher胎,Tubeless胎三者比較。
管胎在輪胎的真圓度,氣密性,路感跟系統重量來比都是第一名,領先其他兩者。
真圓度,管胎是一個完整的圓形,黏在框上而已。管胎當然第一。
氣密度,管胎更不用說,是一個完整的完整的圓形不需要卡入框勾裡,也沒有氣密性
的問題。
路感,因為是完整的圓形,在路上受壓,形變也最小。有最好的路感。Tubeless胎沒
內胎次之。
Clincher胎,內胎與外胎間有縫隙,主要支撐靠內胎,外套形變最大,還可能造成蛇
咬破胎,路感最差。
管胎以相同框高跟胎寬來說,絕對是重量最輕。
基於以上4點,管胎框煞絕對是公路車最佳組合。
什麼廠商“號稱”Tubeless胎滾動阻力最小,這很雞賊。以上面四點來說,
管胎形變最小,自然功率消耗流失最小。Tubeless胎怎可能滾動阻力最小???
況且滾動阻力最小,並不代表一樣的功率,Tubeless胎的整體速度最快。
以一樣的框高的輪組跟一樣的胎寬來比,管胎絕對整體重量最輕,當然一樣的功率
輸出,管胎一定最快。
所以從科學角度來思考,管胎跟框煞才是公路車最速也最佳的選擇。
也難怪職業車隊,三大賽黃衫車手都是使用管胎框煞。
廠商們不該為了利益而漠視事實,強推碟煞Tubeless胎。
