BLUE LUG YMK Crank Set

The original Blue Lug crankset designed for riders who appreciate straightforward bicycle components with a little extra character. Featuring a distinctive three-arm crank design, the YMC brings back a style of crank that has become increasingly rare on modern bikes

With its clean, uncomplicated design and practical narrow-wide chainring, the YMC Crank Set is built to keep your drivetrain simple, reliable and ready to ride

A Three-Arm Crank with Classic Character

Three-arm cranks aren't exactly everywhere these days — which is precisely why we like the YMC

Blue Lug has kept the design deliberately simple, avoiding unnecessary details and focusing on what matters: a clean-looking crankset that works well and suits a wide variety of bicycle builds

The three-arm design gives the YMC a distinctive appearance without making the crankset feel overly complicated

Designed for 1x Drivetrains

The YMC is designed as a 1x crankset, making it an excellent option for riders who prefer the simplicity of a single chainring drivetrain

With only one front chainring to worry about, a 1x setup provides straightforward shifting and a clean-looking drivetrain — ideal for everyday bikes, gravel builds, commuters, touring bikes and custom bicycles

Narrow-Wide Chainring Helps Prevent Chain Drops

The YMC Crank Set features a narrow-wide chainring, with alternating tooth profiles designed to help keep the chain securely engaged with the chainring

This makes the crankset particularly well suited to riding where the drivetrain may experience more movement, including gravel roads, rough surfaces and everyday off-road riding

Offset Crank Arms for Practical Clearance

The YMC crank arms feature a slight offset to help provide clearance between the crank and the bike's chainstay or kickstand

It's a small but thoughtful detail that makes the crankset easier to live with across different bicycle frames and setups

Ideal for Custom & Everyday Bikes

The Blue Lug YMC Crank Set is a great choice for riders building or upgrading:

• Gravel bikes
• Commuter bikes
• Touring bikes
• ATB and all-terrain bikes
• Everyday utility bikes
• Custom steel bikes
• Japanese-inspired bicycle builds

Its simple design makes it particularly easy to pair with other classic and modern components

Why Choose the Blue Lug YMC Crank Set?

The Blue Lug YMC Crank Set proves that a crankset doesn't need complicated features or flashy details to be interesting. Its rare three-arm design, practical narrow-wide chainring and thoughtful crank-arm offset make it a simple, versatile and characterful choice for a bicycle build
