Haro Bikes Steel Reserve 1 Matte Black

The Haro Steel Reserve 1 is a rugged, BMX-inspired dirt jumper built from the ground up to conquer pump tracks, skateparks, and massive dirt jump lines. Featuring a bombproof 100% chromoly frame paired with a rigid, tapered chromoly fork, it delivers stiff, razor-sharp handling and ultimate responsive control. Outfitted with sealed bearings all around, robust double-wall 26" rims, high-traction tires, and a precise Halflink chain that pulls the rear wheel in for a tight 399mm chainstay, the SR1 comes complete with a Tektro disc brake and Haro Baseline 3-piece cranks, making it ready to roast right out of the box.

Haro Steel Reserve 1 Dirt Jumper Bike - Matte Black (26" Wheels)

Meet the all-new Haro Steel Reserve 1, a dedicated dirt jumper built from the ground up to go sky-high and handle aggressive, progressive park and trail abuse. Drawing deep inspiration from Haro’s legendary BMX heritage, the SR1 is the perfect gateway machine for riders looking to master the local pump track, flow through skatepark bowls, or roast big sets at the trails. Engineered to deliver a highly agile and responsive ride feel, this 26-inch freestyle weapon blends bulletproof materials with dialed geometry, ensuring you have the ultimate confidence when launching into serious airtime.

The foundation of the Steel Reserve 1 is its bombproof, 100% full chromoly frame. Crafted to survive hard casings and continuous big-impact landings, it features a modern tapered, integrated head tube that houses a rigid 100% chromoly fork. This fork is heavily reinforced with a one-piece CNC internally threaded steerer tube and tapered legs, maximizing front-end stiffness for precise, flex-free tracking up steep transitions. The frame is anchored by a double-row, sealed bearing Euro bottom bracket, ensuring smooth crank rotation and a low-maintenance interface that resists the dust and debris of loose dirt fields.

In the drivetrain department, the SR1 is spec'd to perform like a pro-level build. Heavy-duty Haro Baseline 3-piece chromoly cranks feature a versatile 165mm length and an 8-spline spindle layout, transferring power to a 28/14T gear ratio. This setup is driven by a premium Baseline Halflink chain, which allows you to slam the rear axle forward inside the dropouts. This achieves a super-short, ultra-responsive 399mm chainstay length, giving the bike a lively, nimble rear end that lifts effortlessly for manualing, hopping, and throwing 360s off the lip.

To withstand heavy, off-axis landings, the bike rolls on robust 26-inch, 36-hole aluminum wheels featuring double-wall, pinned rims with a wide 30mm inner width for superior tire profile support. The wheelset spins on high-grade, double-row sealed bearing hubs with a secure 3/8" front axle to eliminate play. For the ultimate blend of rolling speed and technical traction, Haro utilizes a staggered, aggressive tire setup: a high-volume 26x2.4" Kenda Booster on the front for elite cornering bite, paired with a fast-rolling 26x2.35" Haro MS5 tire out back. Braking duties are handled by a reliable Tektro mechanical disc brake clamped to a 160mm rotor, delivering powerful, easy-to-modulate slowing control when dialing in your speed between lines.

The cockpit is custom-tailored for technical riding control, highlighting wide 780mm aluminum handlebars with a tall 50mm rise and an oversized 35mm clamp zone, locked down by a short-reach 50mm aluminum stem. Touchpoints are dialed with premium, comfortable "CK" (Chad Kerley) grips and a durable Baseline 2-piece Pivotal saddle mounted to a 27.2mm alloy post. With its sleek matte black finish, integrated frame seat clamp, and pro-level spec sheet, the Haro Steel Reserve 1 is a durable, well-specified dirt jumper that offers incredible performance and structural integrity for its price point.
