I have a 2008 Trek 7.2 fx that I purchased brand new –had it for 10 years. I have probably put 2500 miles on it since then without changing out anything or upgrading any of the factory components. You guys that ride a lot give me some ideas of components that I would probably want to upgrade to in the near future. I plan to do a couple 50/100-milers in the next year or so. Maybe you can share some of your mojo with!

If I upgrade to a better chain, should I upgrade the cassette, crank, and derailleurs also? Which components do you guys suggest?

If you've kept the chain (and other oil-able parts) oiled & adjusted, and everything is functioning OK, there's no reason to change out anything but the tires and tubes.

You've got many more miles of smiles left in the original equipment. By keeping my bikes oiled and adjusted I find that I don't NEED to replace anything but tires for 15,000 to 25,000 miles - and sometimes a lot further.

On the other hand, IF you're just wanting to "tweak" it with more expensive components, there's no limit to how much money you can WASTE on it.

I agree that there is no big reason to change components on a bike that has only 2500 miles on it, aside from tires and tubes. Those items dry out over time and 10 years is old for tires and tubes, regardless of miles or tread.

On a 10 year old bike, the best recommendation is a top to bottom check to make sure all components are properly adjusted and torqued. Safety first, do the brakes work good? Do all gears shift good? Any annoying clicks or rattles?

My bikes are loaded with old school components from the 1980s and 1990s. They are mostly good quality Shimano XT components, but nothing wrong with Shimano 105 or LX stuff either.

If your chain doesn't have a quick link for easy removal and cleaning, that is one thing I might add. I remove my chain every 500 miles or so and soak it in mineral spirits, then re-install and lube (50-50 home made mix of chain saw oil and mineral spirits).

Over the summer I was on a bike tour in Germany and pedaled about 2500 miles. The only thing I did was wipe off the chain and re-lube every week or two, and occasionally re-adjust the disc brake pads. Once good bike components are properly installed and adjusted, it is amazing how well and how long they will work without having to do much to them.

Welcome to bikejournal, tco27!

I'm sure it's just me, but personally, I find that using a chain tool to break and remove a chain is a heck of a lot easier than getting one of those "quick" links to work Of course, I'm using 8-speed components, so I don't have to replace the pins.

And I seem to go through chains faster than anyone else here admits. At 2500 miles, I'd probably be about halfway through my second chain. If you're worried about such things, a chain checker

will let you know how worn yours is. If it's only a little worn, you can just replace the chain. If you're having trouble (skipping under load), you'll need to change the cassette as well, and maybe the chain rings if they're worn, too.

I agree with those who say there's no need to "upgrade" anything.

In terms of upgrades to chain/cassette/crank/derailleurs, these are things you are not likely to notice as being plainly better. When the chain is worn out, and is not REALLY worn out, replace it (and you can replace it with a better quality chain, no reason not to) and you can prevent wearing out the chain rings and cassette cogs early. If you have kept the chain lubed for your 2500 miles, it is probably still fine (unlike ericrrrm, I tend to get over 3500 miles before the chain checker calls it 75% worn out).
When the cassette cogs are worn out, which they will be eventually, you can upgrade those, etc. etc. Note that a cassette or chainring that is REALLY worn out shouldn't be used with a brand new chain--the chain would tend to skip. Practically speaking, a shop mechanic could let you know what is worn out or not functioning well. Maybe your brake cables or shifter cables aren't in good shape after 10 years.

On the other hand, if you are thinking of upgrades in terms of doing longer rides, there are practical things to think about in terms of upgrades.

[Though I will insert a quote purportedly from Eddy Merckx, "Don't buy upgrades; ride up grades." I tend to say it's far more about the legs and lungs than about the bike.]

Tires are the single most effective upgrade you can buy--high quality tires with smooth tread and supple sidewalls will significantly reduce the effort needed to ride long and fast on the road.

You might look into a more comfortable saddle for longer rides.

If your position is uncomfortable, then look at different handlebars or stem or maybe cranks of different lengths for a better fit.

You might think about changing the gearing to help you climb hills or go faster if you find yourself spinning out in high gear.

That would be my take given what you seem to be asking about.

Thank you guys for your feedback. I will have some Continential gatorskins and new tubes on her in a couple days. Will also get a new chain and a new saddle is in the works too.
