I bought this simple stand to use for lubing my chain. It holds the bike up using the chainstays. The problem I found when I used it today is that my rear derailleur cable runs under the chainstay, which means the stand puts pressure on the cable. I'm new to biking, but that just doesn't seem like a good idea. Is this okay, or should I return it and get a stand that makes contact in a place with no cables?
