I started riding this spring after back surgery put my running out of commision last year. I bought a Schwinn Varsity 1200 and had my local police department tech. adjust and tune it. It rides ok, but it is a $200 bike. I got a TREK Millennia today that needs a little tlc. I can't find much information on it. Does anyone know anything about these bikes? Any suggestions on upgrading components?
The saddle has springs and the seatpost looks like it's a "suspension" version. Not sure but that might be overkill. Or they may cancel each other out. Are you sure you want/need to upgrade components? Doesn't sound like you've ridden it much, so it might be good just to ride it for a bit to see how it is then decide. Probably repack anything with grease & ball bearings - wheel hubs, bottom bracket & headset. Brake pads likely dry if it's been sitting a long while.
The seat is quite bouncy. As far as components I am not at all sure. I was just wondering if anyone knew about them. If there was a certain component that is typically a problem and could be alleviated with an upgrade It would be helpful to know before I have issues. I will just ride it how it's sits for now. I was running 30-50 miles a week so I imagine my biking should be roughly 3-4 times that if I keep the same time frames for outings.
