Now that the weather is warming up, the cycling season is approaching.
I prepared by replacing the aluminum wheelset for winter cycling with a carbon wheelset. Last year, my bike frame broke, so I urgently bought one from Carrot, but once I rode it, it fit so well
(I felt it while riding enthusiastically at last year's Mungyeong Saejaegil Giro Pando)
and the performance was so good that I sold my main bike (Time Diva flagship), which was heavy and felt lacking in some way, gave my wife some spending money, and replaced the first and second bikes with used carbon road bikes and lightweight aluminum wheelsets.
With the remaining money, I did some lightweight modifications and went from about 7.2kg at purchase to 6.4kg today, and I feel so good about it ^^
The lightweight details are Dura DI2 levers/front derailleur, crank, sprocket, brake arms, quick release, brake outer cable, seatpost titanium bolt, chain,
and carbon saddle.
