Judy Silver, 27.5" Boost fork, 100mm, w/ remote Lockout


XT 11-spd Shadow rear derailleur


WTB Comfort Sport saddle


Shimano Mechanical BR-M375 disc brakes


The PD4 does it all. Built using X6 series lightweight aluminum, the PD4 frame features a tapered internal headset and internal cable routing to keep a clean frame and its housing tucked away. Its 1x drive train provides a 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 tires with reflective sidewalls. 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.
