Thanks to Anonymous and Rose for the advice on how to cure my emptiness. =D I will act on it as best I can.
Yesterday I took my bike out to the Memorial Park Picnic Loop for a few rounds. It felt good to get on my bike and just pedal with nowhere to go and no one to care. Of course everyone else on the loop was way faster than me and kept passing me up, but I didn’t mind. It just felt good to go fast. I was suprised at myself. I used to hate the picnic loop cause it’s short and gets boring. But for some reason this time I didn’t mind so much.
This time, my front derailleur was fine. Not sure what changed since the MS 150, but oh well it works.
