I am new to mountain biking but picking it up quickly. I am in the process of upgrading the components on my Nishiki to 9-speed Shimano XT (shifters, cassette, derailleurs-front/rear, etc.). A nice fellow using this site advised me to support my local bike shop but those guys are way too expensive. I found all the parts @ Jenson.com and thought I was getting a decent deal but it has been two weeks and the parts still haven't shipped yet. Can you suggest a better yet still inexpensive alternative? Thanks for any input.
