I’ve been thinking about all the changes in bicycles since I first started going riding with my school bike club when I was a kid in the early 90’s. When I mention technologies, I’m not necessarily claiming that they were invented since the early 90’s, but that they came into greater popularity. I’ve tried many technologies, and given up on many (mostly because of my own riding style and preferences, not necessarily because the technology was a failure). Here’s my list of modern cycling innovations, feel free to add to the list if I’m missing some things. Which technologies have you tried, which are still in use in your current fleet of bikes, which did you stop using and which have you not yet owned or tested extensively?

Cantilever brakes- Still have them on my cross bike.
Aluminum Frames- I have had some, but don’t currently have any.
Linear-pull “V” brakes- Currently have them on my MTB
Suspension Forks- Have had several, currently have none.
Integrated shifting/braking- I have it on two bikes.
Rear suspension- I’ve owned two, but currently have none.
Disc brakes- I have had two hydro systems and one mechanical, but don’t currently have any.
Clipless pedals- I currently run them on all (4) of my bikes.
Carbon fiber bicycle frames- I currently have one, but it’s for sale.
Aero-bars- I have some clip-on bars I use for TTs.
Tubeless tires- I was running Stan’s on a mountain bike, but currently have tubes in all my tires
Aero-bladed spokes- Currently have two sets of wheels with them
29er MTBs- I have one
Ceramic bearings- Currently have them in one wheel set.
Bike computer (Speed/distance) - I have one.
GPS- Have one
Carbon wheels- Haven’t tried
Electronic shifting- Haven’t tried
Power meter- haven’t tried.
