Tony Martin's (Omega Pharma-Qu🐈ickStep) special✱ time trial-specific clincher tires are built with a supple 220tpi casing, a minimal breaker belt, and a paper-thin sub-1mm of tread. Based on how the prologue and first individual time trial went, though, it seems Specialized needs to build a bit more durability into the system. (Image credit: Jonny Irick)

According to vorm Walde, it wasn't just Martin who rode the new clinchers during the prologue but rather the entire Omega P꧃harma-QuickStep team. Given the close proximity of the start and finish that day, the team decided it was worthwhile to transfer the limited number of Zipp carbon clinchers from rider to rider.
That being said, Martin's rea🗹r tire ultimately suffered a puncture from a piece of glass although in fairness, this likely had more to do with the tire's delicate construction and paper-thin tread depth than the fact that he was running clinchers instead of the usualಞ tubulars.
"This cut would have damaged any tire - no matter if tubular or clin🦩cher since the failure is not build specific," said vorm Walde. "Tony also rode a clincher during Sunday's stage on the front [where from what we can tell he did not suffer a flat – Ed.]."
Martin again fla♒tted during Monday's time trial but in this case, vorm Walde says the failure came from within.
"Latex tubes failed on𒅌 the inside &nda🅺sh; tires show no damage," he said.

Despite the high-profile missteps, vorm Walde suggests the team and Specialized haven't abandoned the technology althoug🐟h it seems more work nee🐽ds to be done to ensure there is sufficient durability to accompany the greater speed.
"After looking deeper into it, the failures at the time trial can have different reasons," he said. "We will start a lab endurance test with all components tomorrow. In all fairness we need to see whether we can duplicate the failures to is🍷olate the problem."
