Oumers Crank Extractor And BB Remover

Oumers offers a versatile bike crank extractor set designed for multiple bottom bracket types. Its 20-tooth engagement fits a wide range of splined cranks, and the tool is manufactured from high-strength steel to resist wear. The kit supports standard square taper cranks and 20-tooth splined bottom brackets, and it can be used with a 24mm socket, wrench, or adjustable spanner. This flexibility makes it a practical choice for DIY maintenance or shop use, especially when servicing mixed components on road and mountain bikes.
Fuaynlk Crank Puller

Fuaynlk’s crank puller is crafted from premium carbon steel with a heat-treated hardness for long-lasting performance. It is designed to minimize thread damage on cranks during removal and includes a compact size for easy transport. The dual-function removable cap supports oversized spindles, and a longer jacking rod increases leverage, making crank removal quicker and more efficient for common square taper and splined crank systems.
LBOKLING Crank Puller

LBOKLING’s crank puller emphasizes durability and portability. Made from premium carbon steel with a quenching process, it resists wear while protecting crank threads during maintenance. Its compact dimensions make it ideal for home garages and mobile repair kits, and the dual-function removable cap allows convenient use with oversized spindles, while the extended jacking rod improves leverage for easier arm removal.
Pawfly Upgraded Crank Puller Set

The Pawfly crank puller set delivers wide compatibility with square taper, Shimano Octalink, ISIS, PowerSpline, and most splined crank arms. It uses high-carbon steel with a three-layer electroplated finish to resist wear and corrosion, ensuring durability over many cycles. A precisely machined 80 mm threaded shaft and puller plug threads help prevent misalignment and damage during bearing installation, providing reliable performance for routine bicycle maintenance.
WEEROCK Crank Set With 170mm Arm

WEEROCK’s single-piece aluminum crank set is designed for lightweight efficiency in single-speed and multi-speed MTB setups (6–11 speeds). The 170 mm arm length and 42T chainring configuration, paired with a narrow-wide tooth profile, minimize chain drops and improve drivetrain reliability. While primarily a crankset, this option is relevant for riders considering complete crank assemblies alongside extraction tools when upgrading or servicing bikes that use 42T rings and standard 170 mm arms.
Alps2Ocean Diamond Hole Crank Arms

Alps2Ocean offers diamond-hole crank arms manufactured from forged alloy 6061. The arms are available in multiple lengths (89–175 mm), providing flexibility for different frame geometries and riding styles. The diamond hole spindle interface requires matching orientation between left and right crank arms. This option is suitable for riders and technicians who work with newer crank systems and need a robust, corrosion-resistant arm set for upgrades or repairs.
Buying Guide: Key Purchase Considerations
- Compatibility: Check crank type (square taper vs splined) and spindle diameter when selecting a crank puller. Some tools advertise universal compatibility, but ensure they fit your specific cranks and bottom brackets before purchase.
- Material and Build Quality: Look for tools made from high-carbon steel or forged alloys with durable finishes. Hardened tools resist wear and protect threads during repeated removal and installation.
- Leverage and Design: A longer jacking rod or an adjustable cap can improve leverage and ease of use, especially for stiff or corroded cranks. Dual-function caps help accommodate oversized spindles.
- Portability: Compact pullers are ideal for home garages and mobile repair kits. If you travel with your bike, prioritize a lightweight, space-saving design.
- Maintenance: Choose tools with corrosion-resistant finishes and consider sets that include a bottom bracket remover for a complete repair solution. Regular cleaning after use extends tool life.
- Warranty and Support: Reputable brands offering warranties provide peace of mind for DIY enthusiasts and professional shops alike.
- Versatility vs. Specialization: If you own multiple bikes with varied crank types, a versatile kit (covering several interfaces) may save time, even if a dedicated tool could work faster for a single crank type.
- Safety and Care: Always follow manufacturer instructions, and avoid forcing components. Misalignment or over-tightening can damage threads or cranks.
