Ummmm there are a myriad factors that have their affect on ride - frame material/design, tire width, tire pressure etc. I have 3 bikes, 2 different wheel sizes, but all 23c width and 3 different materials. The ti/650 has the smoothest ride with the least road noise and most bump absorption, followed closely by the all carbon/700c bike and lastly of course the aluminum/carbon fork/stays/700c bike. Oh - I almost forgot the Marin - all aluminum, wide tires - 700 x 35c, rides like a tank......I can take it over any bump or through any pothole I want to but I feel it plenty. I think I need to let some air out of the tires
