2020 Trek Supercaliber XC MTB Race Bike

Random question for you SuperCal owners, is it a noisy bike?

The reason I ask, is that was at my local XC park this weekend and there were a couple off pretty quick young guys hot lapping their SuperCal’s and they were super noisy. Lots of clunks and bangs. I wondered if it’s just the transfer/effect of the stiffness? They look like a fast and very efficient bike. Beefier than you’d expect.
