Road Cycling - how long does stuff last?

I ride a Calfee Luna with a 10sd Chorus group, and I live in NY.

I have a little over 1,500 miles on it so far since 12/30/02 (when I got the bike new)and am now in a groove of putting on 200+ miles/wk.

About how long will the chain and cassette last?
What about tires, I'm running Michelin Axial Carbons, and just this afternoon I took out 2 "pretty big" pieces of glass out of my front tire, and they left about .5mm wide cracks...is this a problem?

I'm no mechanic, should the bike go in for a tune up soon?

Curious, I wipe down and "dry lube" my chain before every ride, is this correct? I ride 5-6 days/wk.

Use a chain checker to keep an eye on the drivetrain. It is really hard to say how long a drivetrain will last, depends on maintainance, whether or not you like to hammer, how gritty your riding area is.
If the glass did not cut the threads of the casing then your tire should be OK.
If you get free adjustment with your bike, it is time to yake it in and have it looked over. If you do not have free adjustment, you still might want to take it in and get everything checked over as it is a new bike and parts are breaking in and will need some adjustment.
If you run a dry lube wipe the chain, lube it and wipe it again every time you ride. The second wipe helps prevent build up on the pulleys and cogs.

Since you use Campagnolo stuff I am sure you will get many many months on the cassette. campy stuff by far will outlast Shimano, so you are good on that end.

Check the chain about every 6mos or whenever since it takes a few seconds.

You may want to bu a non Campy chain if you want. Many people do as they can be alittle cheaper. But as far as the cassette I am sure you can get well over a year out of it. I would not worry for some time yet.

Get a good mechanic's book like Zinn and the Art of Road Bike Maintenance. It'll run you around $30 and pay for itself many times over. Even if you never do the work yourself, you'll know what to look for and what questions to ask of your mechanic.

Check your chain at 1,500 miles for wear. Link to link should be exactly 12 inches when new. As the chain wears it will grow (not stretch). At 12 1/16" it's time for a new chain. If you ride it until 12 1/8" your cogset may need replacing. I rode many times in the rain this spring (I live in Upstate, NY, too) and my chain is at 12 1/16" at 1,500 mi. I attribute this to many wet and grimy rides. Some people get more miles from their chain, but 1,500 mi. is pretty standard for me.

If you run a good chain and keep it clean and lubed your cogset and crankset will last a few thousand of miles.

Narrow chains are shorter lived than wider. Wear is judged by chain stretch as alluded to. Chains (and socket tool sockets: 1/4", 1/2" etc) are about the only world wide English standards still around, so one link is !" long. If a 12" ruler does not fall on the same place on the links, and the lengthening is more than 1/16" in 12 inches chain is near end of life. Not too many options for 10spd chains, $ or $$. Cassettes are usually good for 2 chains, sometimes 3 chains. Chainwheels for 3 to 5 chains. It is obvious when a new chain is incompatible with older gears. New bikes tend to stretch the cables and a tune up is usually a quick cable adjust and lube job. These are easy to do and you should find out how it is done. Occasionally wheels drift out of true. Tire cuts are inevitable. As long as the tread cut doesn't expose much of the cloth casing or penetrate it you are "OK". Tires wear out in 1500 to 3500miles, faster on the rear. Check the tread for wear through, skids especially can sandpaper off tread at an alarming rate. Pick up the bike and slowly spin the wheel looking at the center of the tread. If any of the carcass shows, change the tire soon. It may blow at any time, and 35mph on a hairpin is not when you want this. Tire loss occurs equally from carcass cuts and wearout in my experience.

I have been cleaning my chain more frequently and I think it last longer. It would stand to reason that it would because most wear is caused by dirt working into the chain and becoming an abrasive. I figure a chain will last 1,500 miles. Do the old 12 links should = 12". If it is longer, even 1/16" change it.

1200 miles per chain? I get far more miles from a chain when I was actively racing. I would get at least 3x times that.

But always check. People tend to replace items before they are in need of replacing.

Here at my buddies shop (the team headquarters) we started to save the tires customers change claiming they were all wore out. We have a pretty good stack of tires still good we give to team riders.
