I took the cage off my derailer and i dont know how to put it back on. When i say cage, i mean the area that contains the cogs.
One end has a part that seems to be to prevent the chain from hitting things. I put that farthest from the hub. Like this: http://bikemag.com/features/onlineex...derailleur.jpg
The other part has a small protective plastic guard which fit best by the cog near the hub (also like in the picture).
The part that worries me is that I rode my bike yesterday and now that protective plastic bit is all worn. Can I take that off entirely? Would that go near the hub or away from the hub (out of the two cogs to put it over) and would it go near the wheel or away from the wheel (out of the two sides of the cogs to use)?
