Reliability!
Bikes are very efficient, plush, light and nice. The only MAJOR annoyance I came across in 2015 were defective components. Good thing there's warranty, but it's a big hassle and especially an environmental issue!
Alright, I did ride a lot, but I've had lots of almost new parts failing.
And you know what, it sounds like a conspiracy theory, but most failures I encountered were on parts from SRAM, Truvativ or Rock shox.
I mean I really love how they work, when they do, they have appealing design and are innovative. But they just don't hold up.
Pike creaky creaky, 1x11 x-horizon RD clutch fuckup, Guide and Elixir trail suck air, press fit BB bearings crumble. Most issues I had several times!
Planned obsolescence comes to mind. They even have it as a business slogan: SRAM - incremental enhancements, perpetual improvements…
WTF?
I buy top dollar bike stuff and do it willingly. And because it's a luxury and a hobby I'll probably buy several redundant expensive bikes/parts if I like them. Even if I don't need them. And I'll pay for them willingly.
But if I buy only one, then need and get several warranty replacements for free - I won't feel like I've made a good deal. I'll feel like someone who's being played with and who is taking part in willingly polluting and wasting our planet.
I'll NOT buy that stuff again and look at other companies with different ethics.
