WTB ThickSlick 700x28c Wired Clincher Tyre Flat Guard Black

It's all in the name...

ThickSlick. A burly casing designed to withstand
the roughest urban conditions paired with a slick tread design that
provides the bite you need in the concrete jungle with impeccable style.

No-nonsense,
slick design provides optimal traction on rough streets. Thick rubber
casing protects against damage from glass, pins, staples, and other urban
unpleasantries. Twice the rubber makes for a smoother ride through the
natural absorption qualities of the material.
