Thanks for all the responses to my first post, I will leave the 20in wheel on the front, I have to believe the designers knew what they were doing. That said, these 100psi tires are a real killer on all but the smoothest roads.
What are my options? I would trade a little road resistance for some comfort, I'm thinking of upping the tire size a little, but am not sure if there are lower pressure tires available??
Thanks in advance. MK
