28 – 175 Crankset 2 Pcs without Bottom Bracket

The 28 – 175 Crankset 2 Pcs without Bottom Bracket is a high‑performance component designed for mountain and gravel bikes that demand reliability, precision, and durability. This crankset delivers a smooth power transfer while maintaining an optimal weight balance, making it ideal for riders who push their machines to the limit.

Key Design Features

• 175 mm Chainstay Length: The standard chainstay length ensures compatibility with a wide range of bike frames, providing excellent stability and handling characteristics.
• Dual‑Speed Compatibility (10‑speed): Engineered to work seamlessly with 10‑speed drivetrains, the crankset offers a broad gear range suitable for varied terrain.
• 38/28T Chainring Combination: The 38‑tooth front chainring paired with a 28‑tooth rear chainring delivers an optimal ratio that balances climbing efficiency and high‑speed performance.
• Lightweight Construction: Made from advanced aluminum alloy, the crankset reduces overall bike weight without compromising structural integrity.
• Precision Machining: Each component is machined to tight tolerances, ensuring smooth engagement with chainrings and minimal play during pedaling.

Material Composition

The crankset utilizes a high‑strength aluminum alloy that offers an excellent strength‑to‑weight ratio. The material undergoes a proprietary heat treatment process to enhance fatigue resistance, ensuring the crankset can withstand repeated stress cycles typical of aggressive riding.

Compatibility and Fitment

• Bottom Bracket Compatibility: While sold without a bottom bracket, this crankset is compatible with standard Shimano-compatible BB86/BB92 standards. Riders can pair it with their preferred bottom bracket for optimal performance.
• Frame Types: Suitable for both aluminum and carbon frames that accommodate the 175 mm chainstay length and have a 10‑speed cassette.
• Pedal Compatibility: Designed to work with standard Shimano SPD or other compatible pedal systems, allowing riders to choose their preferred pedal type.

Performance Benefits

The combination of a lightweight frame and precise engineering results in several tangible performance advantages:

• Enhanced Acceleration: Reduced rotational mass means quicker response when shifting gears or accelerating from a stop.
• Improved Climbing Efficiency: The 38‑tooth front chainring offers a lower gear ratio that aids in steep ascents while maintaining cadence.
• Stability on Rough Terrain: The 175 mm chainstay length provides a stable platform, reducing wobble and improving control during descents.

Installation Guidance

Installing the crankset requires careful attention to torque specifications and alignment. Below is a concise step‑by‑step guide:

1. Secure the bike on a stand and remove any existing cranks.
2. Align the new crank arms with the frame’s bottom bracket shell, ensuring that the chainline remains centered.
3. Insert the bottom bracket (if not already installed) and tighten to the manufacturer’s torque setting.
4. Attach the chainrings using the supplied bolts, tightening in a cross‑pattern to maintain even pressure.
5. Reinstall pedals, ensuring proper clearance with the new crank arms.
6. Check for any play or misalignment before riding.

Maintenance Tips

• Regularly inspect chainring bolts for tightness; loose bolts can lead to shifting issues.
• Keep the crankset clean by wiping with a damp cloth after rides, especially in muddy or sandy conditions.
• Apply a light coat of anti‑rust spray on the crank arms if stored in humid environments.
