Lets be honest here. With advancement in geometry, saddles, wheels, tyres, clipless, design on downtube to improve compression (fix), gears etc especially in the last 10 to 15 years, there is no way in hell that a bike older than that is going to be a better ride.
Sure a 20 year old bike can be functional but certainly not the ride quality. The steel and Ti frame will hold because they can take the knocks, don't suffer from metal fatigue but the components will need changing to newer stuff from time to time.
What is clear is that newer bikes eventually will become harder to fix DIY, proprietary components like seat posts will be costly to replace, and more components will be more fragile to keep a lean weight.
What is good is that new technology, designs and range of colours in both frame and componentry attracts more people into cycling and that does a lot. So we should applaud this.
