I would count as a bicycle racer and crazy mountain biker I guess.

I think the thing is a lot of bicyclists are not really doing things half-assed YOLO style.

Bicycle mechanics are rarely really professionals. There's very little training or education requirement for being one compared to motorcycles or cars.

I have had a lot of cases where so called professional bicycle shops did work that was so bad they'd be in legal trouble if they were working on cars. And I can and do buy most of the same tools they do.

The only thing I really draw the line on is I do not do major wheel repairs or build wheels or disassemble & service hubs. Those jobs are so rare I just can't justify the space or cost for the tools. If I only need something once every 10 years I just can't see dedicating that amount of space & money to it.
