Out on our usual 20 mile tandem toot this afternoon and about 1/4 mile from home: KaBoom!
Rear tire blows! Why fix it alongside the road; walk the rest of the way home and check it out/fix it in the garage workshop.
Found a 1 inch slash right through center of tire casing of our Maxxis Detonnator rear tire. Checked the tube and found 2 rips in the tube. Double checked tire, and sure, there's another 1/2" cut through the tire about midway between center ridge and sidewall of the tire. Double blowout . . . a first time for us.
What the heck did we run over?
We are quite conscious of where we ride and avoid debris, whether it's glass, potholes, or alligators (treads ripped off from truck tires). Not a clue!
Replaced the Detonnator with a Maxxis Re-Fuse, a model that is more punture resistant.
Dissected an old Re-Fuse a while back, and it has a mesh layer of Kevlar in that model that defies most punctures except the tiniest sharp things like big cactus needles and tiny slivers of glass. So, disected the Detonnator we just blew to compare; no such Kevlar layer.
Checked mileage in our log and the Detonnator blew after 1,097 miles; previously a Re-Fuse rear tire on the tandem wore out after 2,478 miles.
Not only is the folding Re-Fuse tire puncture resistant, it weighs 15 grams per tire less than the Detonnator and rolls every bit as nice. Price is the same.
Have you had any similar experiences?
