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 count: 30 spokes per kit 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).
