You reckon it’s the carbon in the wheels and frame that give the bikes that cool hollow sound rolling over rough terrain? Or is it tire technology? Bikes didn’t sound that cool 20 years ago.
Wondered that myself. My theory is it's a mix between the size of the modern tires, tubeless setups and just how fast riders are nowadays. But you might be onto something with large tube diameters and thin walls of modern bikes.
20 years ago bikes all sounded like Orange bikes going down the hill. All you could hear was rattling and chain slap, bikes are quiet now and all you can hear is the hubs and the tires tearing up the soil.
You also have clutch derailleurs and common chain stay guarding to thank now as well. You don’t realize how much noise these kill until you have one loosen up after riding quiet bikes. (My bikes aluminum with aluminum wheels but runs silent with these modern niceties)
Is it pipedream? Because when I look at it a lot of it reminds me of Rockstar but I'm getting old and these guys definitely ride it differently than I do
Its tough to imagine riding without it now. So magic. All the bikes.
