I reciently started doing my own maintance on my bike since i dont have to cash to keep showing up at the LBS eveytime i abuse my bike. its about that time i replace my chain. i just put on a new cassette(i have xt everything also an 8 sp). do i need to go w/ a shimano IG chain? if so, what would u recommend? ive thinking of the ig 90 8 sp. because of cost, but im still open to anything else out there that would be more durable, and give better performance. like i said, im new to doing my own maintance, so i dont really know whats compatible other than being toldthat hg stuff goes w/ the ig chain.
