The PD4 does it all. Built using X6 series lightweight alloy, the PD4 frame features a tapered threadless internal headset and internal cable routing to keep the cockpit organized and free of obstructions. Its 1x drive train provides an extremely wide gear ratio, yet keeps things light and simple with no front derailleur and shifter to deal with. Lightweight and durable Weinmann U-28 alloy double wall rims are strong and built to last and matched to Kenda's Kwick Seven.5 27.5 x 2.0 reflective sidewall tires. On top of this, the PD4 features a Shimano 11-speed Deore XT Shadow rear derailleur and a RockShox Judy Silver suspension fork complete with a remote lockout that allows you to create a rigid fork on the fly, helping to turn your sprinting efforts into faster speeds.
