Just come across this [url= http://bikethomson.com/thomson-weighs-in-on-trek-recall/ ]guide on safe lifespan on Thomson's website[/url]
Have to say that 10000 miles / 3-5 years seems a tad cautious?
I've got a selection of Thomson stems and seat posts and the youngest must be 3 years old. I've not seen the Trek issue so what say the STW massive?
lucky the car industry doesn't work to these kind of numbers
I think it's bollocks. Maybe on superlight parts, which Thomson aren't. But then they're also the only stem manufacturer that thinks it's normal for faceplates to break in half.

I dunno, 10,000miles is pretty much exactly when most cars have to go into the garage to get a bunch of stuff replaced. The more solid bits last longer, but then with 100-200bhp to push it along, adding a few grams to a suspension linkage isn't such an issue.
And I suspect the average weekend warrior takes a lot longer than they care to admit to clock up 10,000miles. It's probably 10 years for most people, especially if they have more than one bike. A really good year for me would be 2000miles on MTB's.
I'd call time on handlebars around 5000miles, 2-3 good years use, no reason stems and posts wouldn't be designed to similar lifespans.

Some oil and a couple of filters?
Costs about the same as a Thompson seatpost. And the same principle applies, you could double the sump volume and filter size and double the intervals. You could make the seatpost twice as heavy too.Some oil and a couple of filters?
creaks less though
any hub manufacturer issue a life span warning ? how about rims ?
having had a thomson stem with 2 hairline cracks 1cm long develop after using it for years i now check stems and bars on all my bikes and replace after a few years or crashes.
Glad that wasn't just me on that.
My oldest active wheels are 11 year old Campag Zondas. Bearings and pick up are a bit tired now but I see no reason to stop using them.
Stem and seat post failures wouldn't be funny but wheels letting go are a whole different ball game.

Why don't you ask them?
Rims tend to die catastrophically due to an impact, or IME after a couple of years the wheels just go baggy and no amount of truing/tensioning will help, and there's little point in building an old rim with new spokes. Either that or they crack around the spoke holes, but unlike stems it's rarely immediate and catastrophic, if your stem cracks you're going to have a big dentist bill very soon.
I've only ever killed one hub, it was one of the 1st gen of ProII hubs that had a habit of splitting in 2. But again, not likely to end in a hospital visit.
