Be careful. You could disrupt the space/time continuum if you ride a relic bicycle from 20 years ago. While riding past the local Rapha group today I noticed that 20 out of 20 bikes had disc brakes. Fair to posit that none of those bikes was so much as one year old. That is how it should be. Pure herd behavior. When someone asked what kind of bike I was riding I replied it was an hallucination. Might as well have been. Sixty years old. Then I disappeared up the road.
