Sorry if there is already a thread on this but I couldn't find it. So I have my workhorse bike that I use for heavy duty chores like going to the grocery, carrying books etc. I keep on tearing the heck out of this bike so I'd like to upgrade it to be more durable. First off it's a Giant, TranSend which is I realize it a low end bike but I plan to have it for a long time I really like it and love riding it. It's having bottom bracket problems and the wheels just keep going out of true, not to mention the deraillers are really cheap. Soooooo..... I'm thinking of new cranks, wheels, deraillers and brakes. I can get pretty good deals on parts but I still need to watch my costs. It seems to me that to find 700C wheels for a hybrid is a custom product thing? I wonder what is the best combo of rims, hubs and spokes to achieve the lightest wheel with most durability? Not really sure, getting a bit overwhelmed with info at this point. I'd appreciate any input you all might have, not sure on what crank set would be appropriate either???? So many questions. Is a road bike crankset usable or the same as that for a hybrid??? Help girls!!!
