The Continental Gator Hardshell is the tire we recommend for those who not only want a fast-rolling tire but also some puncture resistance. We recommend this tire to fixed gear riders, fast paced commuters, and as a high quality training tire. 

Here's what Continental has to saw about the Gator Hardshell:

"Puncture protection and mileage are the strengths of Hardshell-ProTection. A wider PolyX Breaker®, the specialist against punctures under the tread centre and shoulders provides for great reliability. The threeply – each layer with 60 TPI – carcass covers the entire tire and makes it a real bastion against urban detritus. The outer sidewalls of the tire are reinforced with DuraSkin® fabric providing even more reliability due to the casing being so well protected. Hardshell tires are the puncture-resistant flagship amongst racing tires – produced exclusively in Germany."
