I am mechanically inclined, and have recently begun making upgrades to my old bicycle, which I hope eventually to culminate in a new frame and wheelset, etc. Lots of web-pages have bicycle parts for sale, but seldom give enough information about the parts to determine if they are compatible with other parts you might order. Also there seems to be extremely wide price differences among (for example) carbon forks that weigh about the same depending on either website or brand. I live in a rural area with no real bike shops, so online shopping is really my only choice. What I really want to know is how to tell what components are quality components, and which are not. Surely there is some publication, online or otherwise that does more than just review a few out of the hundreds of products available? I haven't managed to find comprehensive reviews of anything I'm looking at anywhere online, and customer reviews are totally useless to me.
