CYSKY Single Speed Crankset 48T, 170mm
The CYSKY 48T single speed crankset uses 170mm crank arms and a 130mm BCD. Designed for square-taper bottom brackets, it supports 1/2″ x 1/8″ chains and is ideal for fixed-gear and single-speed setups. The package specifies a 48-tooth chainring, with a 9/16″ pedal size, and does not include a bottom bracket. This crankset aims to minimize overlap between crank arm and chainring bolts for smoother operation, with compatibility for track and road bikes optimized for single-speed use.
WEEROCK 42T Charing Crank Set, 170mm
This 42T, 170mm WEEROCK crankset is crafted from aluminum alloy and is compatible with single-speed bikes and multi-speed MTB bikes (6/7/8/9/10/11 speeds). The design emphasizes a narrow-wide chainring to help prevent chains from dropping. Weighing about 0.6kg (1.32lb), it provides a balance of strength and lightness, with a focus on durability and chain retention for single-speed and folding-bike applications.
CYSKY MTB Crankset 58T, 170mm
The CYSKY 58T crankset uses a 58-tooth chainring with 170mm crank arms and a 130mm BCD. It’s designed for single-speed, fixed-gear, and Dahon-style folding bicycles, with a square-taper interface and 9/16″ pedals. The taller ring offers greater gearing for flatter rides or riders seeking higher top-end speed, while maintaining a clean single-speed setup.
PETCHOR Square Taper Crankset, 170mm
The PETCHOR crankset features a 170mm arm and 104BCD, with a removable 32T chainring. Made from high-strength aluminum alloy, it emphasizes durability and rigidity. The design supports 1/2″ x 1/8″ chains and includes a three-piece chainring setup for easy customization. The product notes frosted/anodized finishes to resist wear and a recommend BB axle around 117.5mm for proper chainline alignment.
BUCKLOS 32/34/36/38/40/42T Crankset
The BUCKLOS crankset is marketed as a lightweight, durable option for single-speed and some fixed-gear builds. It offers multiple chainring sizes (32–42T) and supports 170mm crank arms with a 104BCD pattern. The set includes options with narrow-wide teeth and both round/oval chainring shapes to improve chain retention. It’s positioned as a versatile upgrade for mountain and commuter bikes seeking a simple, reliable drive train.
Buying Guide: Key Purchase Considerations
- Chain compatibility: Ensure the crankset supports your chain width (commonly 1/2″ x 1/8″ for single-speed bikes) and the correct chainline for your frame.
- Crank arm length: 170mm is common and pairs well with many frames, but verify pedal clearance and comfort for your height and riding style.
- BCD and chainring options: A 130mm BCD is standard for many track/fixed-gear cranks; consider narrow-wide teeth if you ride on rough roads or have a tendency to drop chains.
- Bottom bracket interface: Most products listed use square taper; confirm compatibility with your BB shell width and type (cartridge vs. threaded) before purchase.
- Weight vs. strength: Aluminum alloy cranksets balance weight and durability; carbon or forged steel variants may offer different trade-offs.
- Removability and modifiability: Removable chainrings and multi-gear configurations can increase future customization potential on single-speed setups.
- Compatibility with folding bikes: Some designs are tailored for folding frames; verify mounting, chainline, and clearance for your specific model.
- Aesthetic and finish: Anodized or frosted finishes resist wear; choose a finish that matches your bike’s look and corrosion resistance needs.
- Installation requirements: Some cranks require specific tools or bottom bracket types; check whether a professional installation is advisable.
Each product above targets single-speed or fixed-gear riders seeking reliable crank options with 170mm arms and standard BCDs. When choosing, balance gearing preferences (tooth count), frame compatibility, and maintenance needs to achieve the best performance for your riding style.
