There are two main differences. The first is that Slick Wax uses an alcohol carrier to deliver the wax lubricant package to the chain surfaces versus Ice Wax 2.0’s water-based carrier. In both cases, the carrier evaporates leaving the wax lubricant on the chain surfaces. As you can imagine, the alcohol carrier in Slick Wax evaporates much more quickly. You can apply Slick Wax right before a ride and it will be ready to give top performance. With Ice Wax, the water takes more time to evaporate so we recommend applying it at least one hour or more before you ride to get the best performance. The second difference is in the wax lubricant package. Both use only natural waxes but the types of wax are different. The package in Slick Wax is a bit more advanced, leveraging multiple types of wax for specific purposes along with some new polymer technology. This allows it to run incredibly clean in super dusty conditions while also providing incredible drivetrain efficiency (hence the “Slick” name).
