The Felt F65 wouldn't accept the 28s, but that's okay because the fork, seat post and seat-stay are carbon fiber. The frame is aluminum (except for the seat stay). But the carbon really soaks up the sharp hits and road chatter in a way I didn't expect. and when I first rode it, I knew it wouldn't beat me up. I also am running the tires at 90 psi for now. And it came with a non-OEM slightly padded seat with a cutout which makes my 60-year-old butt happy.
Yesterday I rode it to the office for the first time. I don't have a speedometer yet ,so while it felt much faster that may just be the road chatter of the 23s talking.
Lots of people (like SMD4) think that the feeling of harsher tires is faster. The Pro Peleton and all their mechanics thought this for decades until the research proved them wrong. When you wear out these 23mm tires, try 25mm if they will fit. Every bit wider helps with improved comfort and traction, longer tire wear, and no penalty in rolling resistance. The data don't lie.
