A true 19# gravel bike in medium/large sizing is pretty darn good for weight.

The difference between a true 21# bike and 19# bike just isn't much. That's the difference I was mentioning in the other thread as it's a realistic average difference in frame weight(1000g) since all other components would be the same.

I was saying that tire width is going to affect specifically the road feel more than frame material.

Blindfolded, i certainly wouldn't known what frame material im riding based on road vibration if I have 50mm tires at 30psi.

'Course, it partly depends on how much lighter...But if we're only talking about a couple pounds, it's not a big deal.
