Box One Expert Spokes Kit

Overview

The Box One Expert Spokes Kit is engineered for BMX race wheel builds with a focus on strength-to-weight optimization. The 30-spoke kit features double-butted steel spokes paired with lightweight aluminum nipples, delivering approximately 50g total weight savings per wheel compared to traditional straight-gauge spokes with brass nipples.

Key Features

• Heavily double-butted construction (2.0/1.5/2.0mm) - Thicker 14 gauge at spoke ends where bending loads concentrate; thinner 17 gauge in the middle section reduces unnecessary weight without sacrificing strength
• Superior strength-to-weight ratio - Double-butted design is lighter and stronger than traditional straight 15 gauge spokes; concentrates material where stress is highest
• Black anodized aluminum nipples - Lightweight nipples (0.35g each) reduce rotational weight compared to brass nipples; anodized finish resists corrosion
• Box Hex logo stamped spoke heads - Branded spoke identification with quality control marking
• Optimized for 451mm BMX race wheels - 218mm spoke length and 30-spoke count designed for standard 20" BMX wheel builds

Technical Specifications

• Spoke gauge: 2.0/1.5/2.0mm double-butted (14g/17g/14g)
• Spoke length: 218mm
• Spoke weight: 4g each
• Material: Steel
• Nipple count: 30 per kit
• Nipple material: Black anodized aluminum
• Nipple weight: 0.35g each
• Total weight savings: Approximately 50g per wheel versus straight gauge spokes and brass nipples

Compatibility & Ideal Use Cases

• Wheel size: 451mm (20") BMX wheels
• Hub compatibility: Any 20" hub with standard spoke hole spacing
• Rim compatibility: Any 20" rim with 28 or 36 hole drilling (kit contains 30 spokes-select appropriate count for your rim)
• Best for: BMX racers; wheel builders prioritizing lightweight construction
• Ideal use: Race wheel builds; custom wheel builds; performance-focused applications
• Spoke lacing: Compatible with 3X, 4X, or radial lacing patterns

Verify rim hole count before ordering (kit contains 30 spokes; use as-is for 30-hole rims or select appropriate number for other hole counts). Pair with compatible hubs and rims for wheel building. Maintain proper spoke tension (typically 110-120 kgf for BMX race wheels) during truing and building.

Shipping is often faster, but some items like this one can take 1–3 weeks to ship.
