你的目標很明確,很好,這樣很好解答。
坦白說,想用換輪組來達成目標,
以我個人的經驗是......算了吧~
想換就換,而不要為了想騎快去換,這樣內心受傷會比較重。
手邊剛好有本熱騰騰的新雜誌,bicycle club 45期。
請翻開p.28,剛好在講騎自行車的風阻。
按照雜誌的圖表.....
時速45KPH,車手輸出功率要400w。
時速50KPH,車手輸出功率要540w。
速度要騎超過45kph.....
車手的ftp,個人平均輸出功率要300w。
平均300w的人開大絕招,給你150%下去跑,
瞬間輸出450w,差不多是你要的輸出功率,讓你剛好跟上。
所以車友您的ftp有多少?
沒有300W個人平均輸出功率,
要靠器材幫你在45KPH再加速.....
你可以考慮在公路車上加馬達。
(我不是開玩笑,真的是這樣)
團騎速度要開到45KPH以上,
這個其實很誇張了,可能是車友都跟到怪獸團。
這樣的水準,台灣業餘比賽都是菁英組等級。
團騎,只要能咬住對方,風阻可以減3成。
換句話說,只要有210W的個人平均輸出,
再開大絕招,你就可機會跟上。
那跟不上的原因有什麼?
器材,有可能,
但是器材不會幫你追上這麼大的功率差異。
個人的看法是,
車友你缺乏判讀地形,還有判讀集團動向的能力。
怎說?
照道理來說,越級打怪跟集團,只要能咬住就好。
為了彌補自己的不足,以快打慢,反應要快。
在集團要加速前,你先加速。
這樣集團速度拉高前,你就準備好了,
就算別人輸出大,速度快超過你,你就退後咬對方背後擋風。
別人加速,你才想追.....肯定來不及。
換言之,面對速度都比你快的人,
你需要的是判斷集團(對方)加速的時機點,
比集團早一步加速,等他們來。
這需要有判斷地形,還有集團動向的能力。
這時你用低框輪,加速反應快,說不定還比較有利。
當你和對手實力差不多時,
器材選擇會是勝負關鍵。
當實力和對手有差距,
瞭解自己和對方的優缺點,才有機會跟上。
所以執著在器材,
把更換器材當作唯一手段,會很浪費錢。
(你要促進經濟繁榮,也很好)
PTT上,很多都是年輕人,
在財力有限的狀況下,普遍不會建議花大錢買器材。
(去01問,大部分都是勸拜的)
每個討論區的生態不同,
不是鄉民要損你,或是不要討論器材。
這幾年器材測試的數據化,
大家可以很簡單去找出評價高的器材。
但比較少有人,會把器材使用和車手一起作連結思考。
人+車,人+器材,比單純看器材困難一些。
但,卻能反映出真實的情況。
想買輪組,趕快去買。
但有沒有辦法幫助你完成目標?
這個就冷暖自知了。
(還是先買功率計好好練,可能比較有效)
