I'd call myself a newer biker. Started riding $60 Target bikes in '02. Graduated to a $300 Schwinn in '03 and started picking up mileage. These days I still have the Schwinn plus an old Huffy 15 speed road bike and a Trek 460 that I'm borrowing to train for and race my first Triathlon. Tend to do around 120 miles a week.
But I don't know a thing about gear/repairs/maintenance. Only recently have I started paying much attention to even shifting gears!!!! Of course, when I did my mileage went way up.
Okay, guess that's all.
