But if you run those Bontragers a bit, get a feel for them and note your ride speeds, and then get some GP 5000s and you'll see the difference in your data (if you measure things like that).
Well, I took your advice and installed the GP5000’s this morning, am running them with tubes until Amazon delivers the tubeless valves. I’ll get a few days on tubes. They measure at almost exactly 28mm wide and I was OK with 80-90 psi this morning. I am usually agnostic to road tire ride quality, but had 5000’s on my Chinese carbon. These do ride smoother and a bit quicker compared to the Bontragers. I am really loving this bike, the ride quality is remarkably smoother than an open mold carbon that I got near 9,000 miles out of. Had to watch a YT to figure out what Trek did to install the thru axles. They have a supplied lever that lives in the rear it seems. I think it can still use a 5mm hex, have to check. Rims were a bit of a pain to mount tires, not sure I want to do it on the road, good reason to go tubeless.
