Box Hex Lab Single Speed Titanium Cogs Product Overview The Box Hex Lab Titanium Cogs are CNC-machined rear sprockets designed for BMX race and single-speed applications using Shimano-compatible cassette hubs. Manufactured from Ti-6Al4V titanium alloy and heat-treated to HRC35 hardness, these cogs provide superior durability and wear resistance compared to aluminum while remaining lighter than steel. The 5mm wide hub interface distributes clamping force across a larger surface area to protect cassette bodies and improve engagement. Key Features Ti-6Al4V Titanium Construction – High-grade titanium alloy offers strength and wear resistance approaching steel while maintaining significantly lower weight than chromoly cogs Heat-Treated to HRC35 – Controlled heat treatment increases surface hardness for improved wear resistance and extended service life under racing conditions CNC Machined – Precision manufacturing ensures accurate tooth profiles for smooth chain engagement and consistent drivetrain performance 5mm Wide Contact Surface – Wider hub interface distributes clamping force across a larger area, reducing stress on the cassette body and minimizing risk of hub damage Superior Shock Absorption – Titanium's material properties provide better vibration dampening than aluminum or steel, reducing drivetrain harshness Shimano Cassette Compatible – Standard Shimano spline pattern fits most modern BMX race and single-speed cassette hubs Dual Chain Compatibility – Works with both 3/32" (standard single-speed/BMX) and 1/8" (track/fixed gear) chains Technical Specifications Material: Ti-6Al4V titanium alloy (heat-treated to HRC35) Hub Compatibility: Shimano cassette Contact Width: 5mm Chain Compatibility: 3/32" or 1/8" Manufacturing: CNC machined Finish Options: Oil slick or natural Available Sizes: Multiple tooth counts (specific sizes not listed) Weight: Not specified by manufacturer (lighter than chromoly, heavier than aluminum) Compatibility and Ideal Use Cases Compatibility Requirements: Compatible with Shimano-standard cassette hubs commonly found on BMX race bikes and single-speed applications. Verify your hub uses a Shimano cassette body before purchasing—these cogs are not compatible with freewheel hubs or other cassette standards. Shipping Note: This item ships directly from the manufacturer if ordered within the USA, which may result in separate shipment from other items and additional shipping time. Ideal for competitive BMX racing and high-performance single-speed riding where durability and weight are both critical. Titanium construction bridges the gap between lightweight aluminum cogs (which wear quickly) and heavy steel cogs (which last longer but add rotating mass). The superior shock absorption properties make these cogs particularly suitable for riders who experience drivetrain harshness or want to reduce fatigue on rough tracks. The 5mm contact width provides additional protection for high-end cassette hubs. Best suited for serious racers and riders who prioritize long-term durability and performance over initial cost, as titanium cogs command a premium price but offer extended service life compared to aluminum alternatives. **Due to unique nature of this item, ALL sales of this product are FINAL.
