各位大大好
小弟想在這請教一個問題, 我想幫國中的兒子組一台公路車, 如今有找到一個適合的二手車架組+Praxisworks zayante Carbon 165mm 48/32 11速的大盤, 因為小孩長得快,為了省錢,所以我想把我原來的鋼管車是用campy veloce 10速變速系統移到這台二手車架上,但遇到一個問題,原來veloce的大盤曲柄長是172.5, 所以我想用原車主的praxis 165mm 大盤,這樣比較適合我兒子目前的身高,想請問大家praxis 11速大盤搭配campy veloce 10速系統會不會有問題?

各位大大好小弟想在這(恕刪)
CyclingTips 有篇測試報導, 10/11速大盤都可互通沒問題
重點是10速Campy變把, 變速器, 飛輪要維持統一
鍊條可用Campy 或KMC 10速
報導裡有提及不同廠商的兩盤間距可能稍有不同
(或是2樓提及Campy本身就有不同世代間的差異)
但"傳聞證據"顯示沒有影響
我想意思是前變速器的左右限制及變速線張力調整範圍內應該都可以搞定

"While the demands for the chain and cassette are fairly stringent, chainrings (and cranksets) are far more forgiving, so it is possible to mix brands as well as 10- and 11-speed versions without having an impact on the quality of shifting.
Thus, cranks from Shimano, SRAM, and Campagnolo are freely interchangeable along with those from all aftermarket brands (e.g. FSA, Rotor, Praxis, etc.). And while it is preferable to match the chainrings/crankset to the transmission, there is no strict need to do so.
Thus, owners of 10-speed cranksets fitted with a power meter do not need to replace the chainrings if they upgrade to an 11-speed transmission. Similarly, an 11-speed crankset will readily mesh with a 10-speed transmission. This is not something crank manufacturers recommend, though, with some pointing to a difference in the spacing of the chainrings as a potential problem, however the weight of anecdotal evidence clearly suggests otherwise."
