AltaLine 3 PC BICYCLE 1 SPEED CHROMOLY CRANKSET w/25T NEON Sprocket

1. Length and Compatibility:

   • 170mm Crank Length: This crank length offers a balanced stroke, suitable for various riding styles including freestyle, urban, and single-speed biking. It’s a versatile size that provides sufficient leverage for power transfer without overextending on each pedal stroke.

2. Spindle Type and Bottom Bracket Interface:

   • 19mm Spindle: The 19mm spindle is robust and compatible with the American (USA) bottom bracket interface, specifically designed to provide a solid and stable connection within the bottom bracket shell.
   • American (USA) Bottom Bracket: This crankset is compatible with the 68mm shell width typical of American BBs, a standard found on many BMX and single-speed bikes. The American bottom bracket (often press-fit) offers durability and is known for its simplicity and ease of maintenance.

3. Bearings:

   • Sealed Bearings: The crankset includes sealed bearings, which prevent dirt and moisture from entering and damaging the internal components. This makes the setup especially suitable for outdoor use and ensures longevity, as sealed bearings require less frequent maintenance than open bearings.

4. Material:

   • Chromoly Steel: Known for its strength-to-weight ratio, chromoly steel is highly durable and resistant to impact and stress, making it ideal for high-performance cranksets. This material is especially beneficial for single-speed and BMX riders who often demand strong, resilient components that can handle jumps, tricks, and sudden impacts.

5. Speed:

   • Single-Speed Compatibility: The crankset is tailored for single-speed setups, focusing on direct power transfer and simplicity without the need for additional gears or derailleurs. This design is ideal for minimalist bike builds and riders who prioritize control and straightforward performance.

6. Color:

   • Oil Slick Finish: The crankset features an eye-catching oil slick finish, which shifts colors depending on the angle of light, creating a unique visual effect. This finish is both stylish and protective, offering a corrosion-resistant coating that enhances the crankset’s longevity.

7. Brand:

   • AltaLine: AltaLine is known for producing high-quality bicycle components that blend style with durability. The brand’s focus on sturdy materials and compatibility with popular bike standards makes this crankset a reliable choice for single-speed enthusiasts and custom bike builders.

1. Teeth and Chain Compatibility:

   • 25-Tooth Chainring: This chainring has 25 teeth, offering a lower gear ratio that’s ideal for single-speed bikes where smooth, consistent pedaling is essential. This tooth count is common for bikes that prioritize acceleration and control, especially in urban or freestyle environments.
   • Chain Compatibility: Compatible with 1/2 x 1/8 chains, the chainring is tailored for single-speed chains, which are thicker and more durable than multi-speed chains. This compatibility ensures a reliable connection with the crankset’s chainring, minimizing chain skip and maximizing drivetrain efficiency.

2. Crank Compatibility:

   • One-Piece Crank Compatibility: The chainring is designed to work seamlessly with one-piece cranks, a standard setup for single-speed and BMX bikes. This compatibility enhances stability, ensuring that the chainring remains firmly attached during intense riding.

3. Material:

   • 6061-T6 Alloy: Made from high-strength aluminum alloy, the 6061-T6 material is lightweight yet durable. This grade of aluminum is widely used in high-performance bicycle components because of its excellent balance of weight savings and structural integrity. The T6 heat treatment further enhances the material’s strength, making it resilient to wear and tear, even under continuous pedaling forces.

4. Tooth Type:

   • Standard Tooth Profile: The standard tooth profile is designed to securely hold the chain, reducing the risk of chain drop. This tooth type is especially advantageous for single-speed bikes, where maintaining chain tension and alignment is crucial for a smooth ride.

5. Color and Finish:

   • Neon Oil Slick: The neon oil slick finish on this chainring provides a vibrant and unique look, shifting hues in different lighting. This colorful finish complements the crankset’s oil slick appearance, creating a cohesive and custom aesthetic. Besides aesthetics, the finish also adds a layer of corrosion resistance, protecting the alloy from moisture and grime.
