Hi,
just a random question I got.
How many km can you typically expect from parts like the Shimano Deore xt groupset or the 105 groupset, compared to Altus, Acera or Tourney components? Taken if all are being taken good care of and everything else?

We've had this discussion a lot. The consensus is the bike doesn't contribute to speed nearly as much as the fitness and ability of the rider.

I believe that the question was about durability, not speed. I, too, am curious if anyone has an opinion on the durability of different component levels.

105 and up, with good maintenance habits, can more or less be considered 'lifetime' components. There are some consumables such as chains, cassettes and chainrings (more or less in that order), but yeah, take care of it and it will last

depends how far you ride .... if you add tyres that roll fast (i.e 1 mile per hour faster than your current tyres, after 5 hours of riding, you will be 5 miles further than using the normal tyres)
if you use a bike that has an aero frame, and it is 1 mile per hour faster on the flats, after 5 hrs you will be 5 miles further than a normal frame
so just with the 2 examples, using faster rolling tyres, and an aero frame, after 5 hrs, you will have covered an extra 10 miles than if you used a 'normal frame and normal tyres'... using the same effort
just an example though and if you are a triathlete or ride audax, it makes a huge difference as every second counts

I actually think the opposite. Structurally Dura ace and ultegra are similar. More expensive components are built to be lighter, which would often mean "less durable."
Then again, I ride dura ace from the 90s so..

I have Deore LX derailleurs on a 2002 Giant Sedona LX, that's 14 years and about 7500+ KM's on it. Shifts like the day I bought it, and honest to God, I've *never* taken an allen key or screw driver to either of them to adjust a thing. No discernible corrosion or play/degradation either.
I just recently replaced the chain, not because I noticed any issues, but more preventative primarily because a new KMC that includes a quick-link only cost $14.50, and makes it easier to remove for cleaning. I consider these lifetime components, and would expect SLX and XT to be even better, unless physically damaged through impact, etc.

Yep. Those steel chainrings found on low end components would probably last three generations.
