Even though I’m a fan of steel bikes, it’s mostly because of the durability of the material. I certainly like the ride quality too, but I think the idea that steel is a more plush or forgiving ride because it flexes or dampens is hogwash. The idea has almost become gospel now just because it’s been repeated so many times. Don’t get me wrong, I know my steel bike frames flex…. I can hear my fender and/or brake and/or front derailleur rub from time to time if they are a little out of whack and I am pressing hard on the pedals. But that is torsional flex.
It’s the idea of vertical flex of a bicycle frame I have a hard time envisioning.
Imagine the arrows to be balancing the downward force of the rider and the bike.
