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. 2019 Haro PD4 27.5" X6 alloy frame Rockshox Judy Silver fork, 27.5" Boost 100mm w/ Poploc & remote lockout FSA Comet crankset, 32T Chainring Shimano Deore XT 11-spd Shadow Plus rear derailleur Shimano SLX 11-spd 11-46T cassette Pivit Alloy adjustable stem Kenda Kwick Seven.5 27.5x2.0" tires w/ Reflective Sidewalls Shimano MT201 180/160mm disc brakes Pedals w/ toe-clips & straps, rear rack & water-bottle cage FRAMESET Frame: Haro PD4 27.5" X6 /6000 series alloy, w/ Internal housing routing & chainstay disc brake mount Fork: Judy Silver TK, 27.5" Boost, 15x110mm axle, Solo Air, 100mm travel w/ Poploc Lockout Remote Colors: Matte Black DRIVETRAIN Cranks: FSA Comet Modular MegaExo, 32T, Megatooth Chromoly Chainring Pedals: VP 335T w/ Toe clips & Straps Chain: KMC X11 11-spd Bottom Bracket: FSA MegaExo 73mm Front Derailleur: N/A Rear Derailleur: Shimano Deore XT, 11-spd Shadow Plus Derailleur Shifter: Shimano SLX M7000, 11-spd Freewheel/Cassette: Shimano SLX M7000, 11-spd, 11-46T WHEELS Tires: Kwick Seven.5 27.5x2.0", 60TPI, w/ Reflective Stripes Wheels/Rims: Weinmann U-28 Disc 27.5", alloy double wall BRAKING SYSTEM Brakes: Shimano MT201 hydraulic, 180/160mm Center Lock Rotors Brake Levers: Shimano BL-MT201 OTHER COMPONENTS Grips/Tape: Velo Triple Density w/ integrated Bar-Ends Handle Bar: Pivit alloy 25mm riser 31.8mm Stem: Pivit Adjustable stem, 31.8x105mm / 1-1/4"x4.125" Headset: FPD DOZER-1160A-2, 1.5" ACB bottom, for 44/56mm Head Tube, w/ 15mm top cap Saddle: WTB Comfort Sport Seat Post: Pivit alloy, 2 Bolts, micro adjust 30.9mm Seat Clamp: Pivit alloy 34.9mm quick release Extras: Rear rack, Water-Bottle cage & Kickstand
