Cycling doesnt have to be expensive. But you've all bought into carbon fiber frames, electronic shifting, disc brakes, computer aides, etc, etc. Steel tubing is time tested and will last your lifetime. A cable attached to a lever moves my derailleurs. Weinmann centerpull rim brakes stop me just fine. If I really want to know, I can calculate my speed by counting rpms. To enjoy cycling you dont need the latest gizmo's. I participate in group rides on a 50 year old entry level plain gauge hi-tensile steel framed bike with plastic derailleurs. I dont have any problem keeping up with the pace. But if you want to be a gear head and spend, spend, spend thats your option not a requirement to enjoy the sport.
