Where I bike, "goathead" thorns abound. These are ingenious little devils with a base shaped like a
medieval mace and a single spine that sticks out like a straight pin. They are designed so that when
they fall on the ground, they often land with the spine sticking straight up. Riding over them is
like traversing a pincushion that has needles stuck in it with their sharp ends facing out.
For normal use, I have Continental Top Touring 2000s on my bike (a RANS V-Rex). They are much better
against the goatheads than other tires I've used (Primo Comets, Tioga Comp Pools) BUT I'm looking to
outfit a spare wheelset with faster, higher pressure tires. Obvious candidates are kevlar tires like
the kevlar Primo Racers and Schwalbe Stelvios, but some swear by certain non-kevlar tires such as
the Schwalbe Marathons.
What's your vote? I need one 26" (559mm) and one 20" (409mm) tire, neither wider than 1.5". Please
speak also to the speed and handling characteristics of the tire, if you can.
Thanks!
