In a state of moderate injury coupled with intense boredom I have compiled this glossary of bike related terms. I am sure we have all been in a bike shop in China and not known what a certain part is called or how to ask for that something that we need, choosing instead to point, repeating "na ge na ge" until the message is conveyed.
Well, I hope this will help. I wrote it myself from scratch so please excuse inevitable errors and feel free to continue to add terms as necessary. I looked around online and was unable to find anything as thorough so perhaps our thread might work its way to containing the definitive English/Chinese bike glossary.
The thought of including pinyin was daunting so I have used #'s for tones. I hope this will make the lives of touring cyclists passing through Kunming easier and aid those that frequent ever sprouting bike shops.
