Oh hai. another bike mechanic here deciding to chime in as the thread has been off topic since the first page anyway
while i agree as a mechanic, i sort of disagree as a cyclist on several things. that being said, i am an aggressive rider that solo rides almost exclusively and often at night. Tubeless is a godsend for me as there are lots of thorns here, and i can run less air pressure and get better traction. i do carry a tube just in case but have yet to have a catastrophic failure in the wild.
hydraulic brakes are another thing i've come around to appreciating. on customers bikes they all suck
Funny thing is that in 1997 when i was like 14, i had the first disc brakes that Hayes came out and i had no clue how to work on them so i brought them to my LBS, who proceeded to contaminate them and then had to wait a couple of weeks for parts and them to figure it out. So then, when they were the "new hotness" they sucked a lot more.
that being said, i also remember a few cantilevers that were a real pain in my ass and just never seemed to adjust right, sometimes due to the cable routing etc of the frame itself. and the incompatibility of lever pull with canti and linear pull that some manufacturers like giant seem to still have problems getting right on their hybrids.
its kind of like when i used to work on Bmw/rover/porsche, the best tech drove a shitty old bronco. i always asked why he didn't have a BMW or something, customers would have an 8k bill and decide they didnt want the car, someone would hydrolock an engine and it sit. he could of had his pick of 740il's, s500's, rovers for next to nothing
his answer was, "work on these pieces of shit all day long, last thing i want is to be in one when im not here"
what works best for one person isn't necessarily best for others. a lot of "serious" cyclists would say ebikes suck. I am a retro grouch at heart, if it were up to me i'd be riding one of the 30+ 90's hardtails i collect with my seat a foot in the air and a negative rise 130mm stem clamped on to my mag 21. Unfortunately, as i approach 40, i found that the bright side of the additional weight of modern bikes and heavy forks, and the increased rotational mass of 29ers is offset by being able to walk the day after i ride. my mag 21sl weighs half what my fox weighs
ALSO- I consider wrenching on bikes to be a noble profession. For me, it is my zen time that i am fortunate to be able to charge people for. Unlike cars and other things, it is very rare to have a bike issue that can't be resolved in an hour or two. its the perfect balance of mentally stimulating enough, without sending someone with ocd over the edge. It is the only job that hasn't followed me home in a negative way, only in a way that finds me spending more time in my off hours on sites like this because it is what i enjoy. I know a lot of people with "careers" making less at the end of the day as well, and while i've done things that made more, it isn't all about the money.
