Negative Positive
Title: 80% good...
Review: I am lazy (and not ashamed!), so the fact that these hard foam inner tubes do away with flats and putting air in my tires is awesome. TINSTAAFL--the ride is now somewhat less "cushy" and the hard foam transmits more shock up to the rider than the air inner tubes. Still a net plus (80/20 for me) b/c no more flats and pumping!The less lazy may rate these as less than 50/50 and be thoroughly perturbed by the rougher ride, so you must consider your "laziness level" when potentially getting these.
Is the review positive or negative?
