So I came home today after school planning to lube the chain after all that riding in the rain. To my surprise, my right spool to use with my rear stand is missing . I have not touched it since i bought the bike around 6 months ago and the last time I checked it, there were no signs of it being loose. So my questions are: Did it come off on its own? or did someone steal it for who the hecks knows why? Why didnt they steal both? or how would it come off on its own? Which scenario do you guys think it is? And lastly, is there a place to purchase just 1 spool?
