Okay.
What is a Shimano Ultegra?
for that matter, what is a derailler?
I've got my guesses, but all the websites I've seen just about buying one... not one of them has told me what it is.
Any website help would be greatly appreciated if you don't feel like typing out the answer!
I just have been through many of the posts and don't see anything about some of the different lingo.
And that's just a start of what I don't understand.
