Sadly, many parts of modern mountain bikes seem to be less durable and not repairable. For most of the stuff I can't or don't want/have time to do, I take into the shop. And generally, they throw up their hands and say it needs to be replaced. Did that with two dropper posts this week. (One needed a rebuild that would cost more than replacement. The other had a (luckily under warranty) faulty cartridge).

I will also say that e-bikes are much more fun than I would have thought. And not very serviceable.

You have to factor in labor costs. The marvel of modern logistics is that it's often cheaper to ship a new part over from across the Pacific than it is to do a proper repair where the faulty part is taken apart and hand repaired.

Take a look at the local rate of machinists and mechanical engineers and then decide whether you truly want to have your bike part "repaired".

One should choose their bike components carefully. I have been able to service every single component on my mountain bike, excluding suspension since that requires knowledge and time I don’t have time to acquire (yet!). As a general rule choosing mechanical components instead of electronic ones has been rewarding on the longevity and repairability fronts. That said some components are consumable, like the dropper post cartridge you mentioned, but to arrive at the point it requires replacement you either used it a lot (I’m jealous!) or it was simply faulty :-/

Might also be a good idea looking for other bike shops in your area. Mine is always trying to recycle and repair components.

Dropper posts are notorious for beaking. Just choose something with a replaceable cartridge.
