Ah finally, time come to replace and refresh my tired bike. Replacing wear chain and rear tire, just to find that my sprockets are also tired (losing my 12-30, but get 11-32 now, LOL). And when I try the new sprocket, suddenly my rear shifting cable is broken. Pushing 53-11 all the way to replace the cable. Ugh, poor bike, you must be so tired. LOL. Thank you Bernard for fixing all these problems.
