I have a Shimano Alivio front derailleur with shifter. It was used for about a season and a half. It works perfectly, the only reason I am not using it is because I have converted my bike to a 1x9. I will also include the chain rings, they are a 22, 32, 42. The 42 is in great shape and was bought new towards the end of last season. The 22 is in good shape and still has a good amount of life left in it but you can tell it has been used. The 32 ring has seen by far most of the use, it doesn't skip and is still ride able but it probably should be replaced in the near future.
I'm pretty open to any thing for a trade and am willing to put down some money also.
The main items that I am looking for are a 10 speed derailleur, shifter, and cassette.
