The 2″ wide pedal crank kit features a one-piece crank with a 44T sprocket, designed to fit a 2″ cup bottom bracket on typical BMX frames. This setup suits riders seeking a wider pedal engagement and straightforward installation. The 44-tooth configuration provides a balance of acceleration and top-end speed for street and park use. Durable construction supports frequent gear changes and torque application common in aggressive riding styles.
170mm Crank Arm Set With BB Kit
This BMX/crankset bundle includes 170mm arms with a 104mm BCD pattern, plus a bottom bracket kit and round chainring bolts. Made from alloy 6061, it emphasizes rigidity and resistance to flex under load. The 68-73mm BB width accommodates a range of frames, while the hollow sprocket wheel shaft suits mountain and road bikes transitioning to BMX components. It’s a versatile upgrade for riders seeking a robust, all-purpose crankset with reliable installability.
Black Ops Blade BMX Chain Ring
This replacement steel sprocket is designed for 1-piece BMX cranks, offering a durable option with standard 1/2×3/32″ tooth pitch. The blade-style chain ring focuses on reliability for frequent gear changes and consistent engagement with the chain. It’s well-suited for riders who prefer straightforward maintenance and components that resist wear over time.
Urban Folding Crankset 44T 170mm
Designed as an adaptable substitute for bicycle repair, this aluminum alloy 6061 crankset uses a 44T chainring, 170mm arms, and a 130 BCD. The frosted inner ring with a silver outer ring project a modern, corrosion-resistant finish. It’s a practical choice for single-speed or fixed-gear BMX setups requiring a lightweight, corrosion-resistant option with solid torque handling for casual and urban riding.
CYCLEZ One-Piece Lowrider Crankset
This kit includes a lucky 7 36T chrome sprocket with a crank and bottom bracket replacement option. It caters to riders aiming for a distinct lowrider look and custom wheel engagement. The chrome finish provides a classic aesthetic while maintaining strength for daily use and occasional trick-based riding. The included bottom bracket helps streamline installation and compatibility with various frame standards.
Buying Guide: Key Considerations For BMX Sprockets And Cranks
- Compatibility: Check crank arm length (typical options include 170mm), chainring bolt circle diameter (BCD) patterns (104mm is common), and bottom bracket widths (68–73mm). Ensure the sprocket tooth count matches your preferred balance of acceleration and speed (e.g., 44T for urban and park riding, 36T for lighter setups).
- Material And Durability: Alloy cranksets (like 6061) offer strength with reduced weight. Steel sprockets provide durability under aggressive riding and frequent gear changes. Consider corrosion resistance for outdoor use.
- Single-Speed And Multi-T gear: Fixed sprocket setups suit single-speed BMX or urban riding. If your frame supports multiple chainring options, verify compatibility with your derailleur-free system and chain length requirements.
- Weight And Stiffness: Lighter alloy cranks reduce rotational inertia, improving flicks and jumps. Stiff cranks enhance power transfer, especially in park and street settings.
- Installation And Maintenance: Look for standard hardware and clear mounting interfaces. A BB kit simplifies installation on various frames, while steel sprockets may require gear tension checks more frequently.
- Appearance And Finish: Finishes such as silver, chrome, or frosted inner rings contribute to aesthetics and corrosion resistance. Choose a finish that matches your bike’s overall colorway and protection needs.
- Replacement Availability: Popular patterns (44T, 36T; 170mm) have broad aftermarket support. Verify compatibility with your current chain length and RPM expectations for optimal performance.
To maximize performance, pair a compatible crankset with a matching sprocket and chain. Consider your riding environment—street, park, or trail—and select tooth counts that align with your preferred balance of acceleration and top speed. Regular inspection of crank bolts and sprocket engagement is recommended to maintain reliability and safety.
