One claim we can all believe is that the GP 4000 S II tire was a genuine class leader, a tire that consistently performed and out-performed when called upon. Now, after 14 years since the original GP 4000 was released, the legendary tire has been given a complete overhaul, including, but not limited to tubeless.
The GP 5000 TL is similar to the regular version but adds an airtight liner, a shaped bead (with softer rubber to make fitting easier) as well as a coarser 180 tpi casing. Continental claims they went through multiple versions, attempting to walk the line between a secure fit and easy mounting.
Continental's trademark Black Chili compound has also received an upgrade in the form of a new formula as well as laser etched tread that is supposed to provide an even greater cornering experience. The company also claims that the texturing also smooths air flow, thereby decreasing drag.
