Description

Haro ESX 4130 Chromoly BMX – Skyway Tuff II Mags, Dia‑Compe Nippon

This mid‑1980s Haro ESX freestyle BMX pairs a 4130 chromoly twin‑top‑tube frame (serial #87053129) with era‑correct components. Five‑spoke Skyway Tuff Wheel II composite mags reduce weight while adding classic style. Braking is handled by black Dia‑Compe Nippon calipers equipped with Kool‑Stop pads and Weinmann semi‑automatic adjusters. The drivetrain features a one‑piece crank, large Pro‑Neck chainring, and Shimano PD‑MX15 bear‑trap pedals, while a Dynamax saddle sits on a lay‑back post for flat‑land tricks. Bolt‑on fork platforms and tall freestyle bars complete the period specification, offering collectors an authentic snapshot of BMX’s formative freestyle era.

Condition

Fair, rider-grade condition. Signs of use throughout. Paint loss, decal wear, and adhesive residue present, particularly near the seat. Some surface rust on hardware. Front brake cable shows fraying. Tires are aged and do not hold air. Mags show grime but no visible cracks. Bearings spin freely. Frame appears in good condition, and other components appear functional, though a full service and safety check is strongly advised before use. Review all photos for detailed wear.

Size (inches)

  • Tyres (outer diameter): 19″
  • Saddle height (top of saddle to ground, as photographed): 20″
  • Frame size (centre BB to top tube): 18.5″

Additional measurements available on request.
