Classic Silver Crank with a Modern Riding Focus

The Blue Lug RMC-II Multi-Speed Crank combines a traditional bicycle aesthetic with the practicality of a multi-speed drivetrain. The combination between the slim crank arms, and the hollow chainring gives the crank an authentic style

This classic styling works particularly well on Japanese-style or vintage inspired city bikes, all-road bikes, gravel bikes, touring bikes, ATB builds, and vintage-inspired bicycles

Whether you're building a new custom bike or giving an existing bicycle a thoughtful refresh, the Blue Lug RMC-II is a simple way to add that Japanese bicycle style, timeless character, and everyday functionality to your ride
