Dogtrousers
Lefty tighty. Get it righty.
I had a steel rimmed wheel in my garage and accidentally ran over it with the car a few years ago. I wasn't sad about it.
Just been thinking about this when I couldn't sleep....
1) carbon bikes
2) sti levers
3) helmets
4) clipless pedals
5) GPS
6) A headset stems.
7) factory wheels
8) wireless shifting
9) breathable jackets
10) Disc brakes.
Crazy how much invention there has been over this period.
Steel rims and rim brakes were great in the wet
Not being a "roadie" I would question a lot of the things on the original list. From a purely personal view:-
Cable brakes.
LED lights for their effect on battery longevity and brightness. Not so impressed with rechargeable -everything. Easily replaceable batteries for me. Choice is getting restricted now.
Modern hub dynamos, especially with LED lights.
Puncture resistant tyres.
Alloy rims for better braking and lighter weight.
Disc Brakes. My experiences have been mostly good though didn't like the Novellas on a Marin I had.
Indexed shifting. A definite bonus for newcomers, but introduce another level of maintenance. I recently had a bike with non indexed shifters and appreciated the simplicity. When indexing is good, it's good. When it's cheap it can be horrid.
If you have large hands, Brifters are OK. Since I don't, gave me sore hands. Shimano Sora, with mouse ear buttons, I liked, though I believe that feature has now been discontinued.
Chromoplastic mudguards.
Modern bike computers.
Cable ties.

Lights that emit enough light to see by.
