Yes- I did 500 miles on the Airhawk R. Proper inflation achieved. The two things I didn't like about. 1- hurt my man berries. I know doesn't sound right, but it always pushed a air pocket into the boys 2- the Airhawk was ok on straight roads but on twisties/curves/swipers, my butt rocked/wiggled around which hurt my lower back. Sent it back for a refund.sirkitrider-2 have you tried an Airhawk and/or a sheepskin? .
