I went through three phases. First I adjusted my child's (I was 9-13?) bike, always fantasizing about a hook-and-cable to the ceiling that I can attach to the metal loop behind the elongated (and lavish) seat. Instead I flipped the bike upside down.
Then in my mountain and hybrid biking days I invested in bike tools. Avoiding to change the ball bearings in hubs/cranks when they were due was more a result of laziness, but delaying the tune-up of derailleurs to perfection was, I imagined, less a result of laziness than lack of a stand.
I'm now entering the road bike phase. On one hand I see that the bike is quite steady when it's upside-down. If I ever dare attempt truing a wheel myself, a stand, even a very solid one, will be wobbly compared to turning the bike upside-down. On the other every bike seems to have a top-access-to-bolts-and-screws design. And hence tuning brakes and derailleurs is inherently easier with the bike on a stand.
I appreciate that an upside-down bike is better than one on a wobbly stand, but assuming it's either a solid stand or none at all, I'm wondering:
Is a bike stand really necessary for pleasant/patient regular maintenance of one's bike?
(Update: And does there really exist such a thing as a "solid stand"? In various repair videos taken in serious bike shops I see that the bike moves way too much with even mild work being done on a screw here or there. It's as if a truly solid hold must grab the frame in three, or possibly two, places.)
