did you ever think maybe some people just don't have the time to build a whole bike. Maybe some can do it but to lazy too. I don't get what your trying to say?? It's okay to ask for help.
Time? With all new parts it would take 2-3 hours to build a bike. Not including building wheels. 2-3 hours is about half the time it takes to do a ride. Doesn't seem too much to me. Lazy? My thoughts too. Seems odd to be lazy when bicycling is a very physical activity. Lazy bicyclists don't make sense. Lazy marathon runner? Overweight marathon runner? Don't go together at all. What I am trying to say is when people spend hours and hours picking out every individual part, and thousands upon thousands of dollars, and then don't spend the extra few minutes and effort to build it yourself and get the satisfaction of building it yourself, you are cheating more or less. You're depriving yourself of part of the fun of bicycling. Bicycling is an intense activity. Seems odd to be intense on the riding, but not the building part. Or maybe the people who hire the building don't really ride much if at all. They want to hire someone to build them a trophy bike to hang on the wall but don't actually ever ride. Yes you can ask for help if its something complicated or you do not have the right tools. Maybe pressing in all these bottom bracket bearings. I hear there are special tools for that and you maybe use Loctite or not and some other black magic to get them not to creak and rattle. Ask for help. But putting the stem on the bike? Putting the derailleurs on the frame? Cables? Cassette and getting the chain length right? Taping your handlebars? Do you hire someone to tape your bars? Putting pedals on the crankarms? Do you do that? What about adjusting the height of the seatpost? Do you take it to a shop to have that done?
