Lane Conditioner

DEFYv30 is a higher viscosity version of the original DEFY conditioner. The specialty blend of top grade oils and unique additives used to create DEFYv30 generate unparalleled performance compared to lane conditioners in the market today. DEFYv30’s enhanced flow-back characteristic reduces the impact of ball tracks through the heads while minimizing the movement of conditioner down the lane to keep the shot more consistent and like the original DEFY, it has been shown with ThroBot™ to last up to 30% longer than other products. This workhorse conditioner offers an excellent solution for high lineage centers to keep your bowlers satisfied, providing a predictable and stable ball reaction that allows them to make fewer, less drastic, adjustments as the pattern changes.
