剛好從pro4轉換到GP4000s2 ,趁路感記憶還新鮮直接回一篇
(以下為個人經驗,非專業儀器測試)
1.MICHELIN PRO4 (23C)
♦PRO4用過 Endurance , Service Course 這兩種規格,路感偏Q ,胎壓打到115也還算舒適不會太顛。壓到小石頭比較不會噴出去
♦抓地力很優,尤其是濕地抓地力很讓人放心 (曾在大雨中下滑太平山也幾乎沒有打滑,過彎超安心)。
♦顏色比較多選擇,可以配車色
♦真的不耐磨,2000-3000就磨到平了 ,胎邊(色邊)部分用久的確會有裂痕,但應該不影響安全
2.馬牌 GP4000s2 (25C)
♢路感較直接也較硬,打到110壓到石頭就會像子彈一樣彈出去XD
♢抓地力感覺略遜pro4,濕地爬陡坡有時會打滑空轉,但胎邊有做胎紋,下坡過彎也算很穩定
♢滾動阻力的部分,在看了山姆叔叔的測試,嘗試由從23C 換成25C , 沒有功率計可以測瓦數,但在心跳及轉速差不多的情況下,之前卡了許久的PR時間也硬是突破了快30秒(烘爐地計時)
目前為了抓地力及操控感 是用前pro4(23c) 後GP4000S2(25c)混搭配置~
