Energy Spikes/different Days
Hello guys, I have this problem, that I find sortof annoying, I have a pretty heavy bike yet some days, I can push it really fast*even if it's not made to* Like I can go in the highest gears on my bike without any problems at all and If I could I'd go even faster on even harder gears, but some other days like today, I was at a really low gears, and it was feeling hard and heavy.
It doesn't feel like I'm tired actually, it just feels like, my gears are higher and harder than what they should be but they aren't.
I'd really like to minimize the number of these days since it's a lot less enjoyable to cycle during these days and I'd like to have a quick and permanent solution to that problem.
Thanks a lot to whoever will help me !
