This is Isabella my first bike! Dropped her on the 5th day of getting her. Heart was in pain. Sakit ah! Used to be very on about wiping her down and cleaning her up. She was gleaming ... after 6 months, I am okay with seeing dirt on her. Dun feel the need to clean her up liao. Neverthe less, still maintain stuff like warming up before riding and not throttling up till after some distance.
