Position One 5 Bolt Chainring 110mm

Product Overview

The Position One 5 Bolt Chainring is a straightforward aluminum chainring designed for BMX and single-speed applications using 110mm BCD (bolt circle diameter) five-bolt cranks. Manufactured from 6061-T6 aluminum with 3mm thickness, this chainring provides a budget-friendly option for riders needing a reliable replacement or gearing change without premium-tier pricing.

Key Features

• 6061-T6 Aluminum Construction – High-strength aluminum alloy delivers reduced weight compared to steel chainrings while maintaining durability for regular riding
• 110mm BCD Five-Bolt Pattern – Standard bolt circle diameter fits cranks using the 110mm five-bolt mounting interface
• 3mm Thickness – Reinforced thickness provides structural rigidity to resist flexing under pedaling loads
• Dual Chain Compatibility – Works with both 3/32" (standard single-speed/BMX) and 1/8" (track/fixed gear) chains
• Straightforward Design – No-frills construction focuses on function and value rather than premium features or aesthetics

Compatibility and Ideal Use Cases

Compatibility Requirements: Requires cranks with 110mm BCD five-bolt chainring mounting pattern. Verify your cranks use 110mm BCD before purchasing—many BMX cranks use different bolt patterns (104mm, 96mm, or proprietary designs). Compatible with both 3/32" chains (standard on most BMX and single-speed bikes) and 1/8" chains (common on track and fixed-gear applications).

Ideal for BMX riders and single-speed cyclists who need a reliable, affordable chainring for gearing changes or replacement. The 110mm BCD five-bolt pattern is less common on modern BMX race cranks but may be found on some older or entry-level cranksets and is more typical on track, fixed-gear, and some city bikes. The range from 34T to 41T allows riders to adjust gearing for different riding styles or terrain without significant investment. Best suited for recreational riders, commuters, or budget-conscious racers who prioritize function and value over weight savings or premium construction. The dual chain compatibility makes this chainring versatile across different single-speed applications.
