The Sugino FIXIE 75 Base + Lockring Set is a dedicated component set designed for use with the SUGINO FIXIE 75 cog system. It is ideal for riders who already use, or plan to install, a SUGINO FIXIE 75 cog.
SUGINO is a Japanese brand known for precision drivetrain components and high-quality machining. This base and lockring set continues the brand’s refined craftsmanship, helping complete the drivetrain area with a consistent and well-matched appearance when paired with the FIXIE 75 cog.
This set includes the FIXIE base and lockring. The FIXIE system is designed so the cog slides into the compatible base and is secured with the lockring, creating a stable rear cog setup. Compared with a traditional standalone cog, this system gives the drivetrain a more integrated appearance while showcasing SUGINO’s dedicated system design.
The lockring is engraved with the Japanese word “フミキリ”（FUMIKIRI）, meaning railroad crossing. This small detail connects with the imagery of city traffic, urban movement and cycling culture, making the part not only functional but also visually meaningful and collectible.
The FIXIE base uses a BC1.37 x 24T thread and is made from chromoly steel. The lockring uses a BC1.29 x 24T L thread and is also made from chromoly steel. The strong metal construction and SUGINO finishing make this set suitable for riders who value drivetrain stability, brand consistency and detail-focused builds.
If you are using a SUGINO FIXIE 75 cog, or want to keep your drivetrain setup matched within the same system, this base and lockring set is a clean and proper choice.
⚠️ Please note: this product includes the FIXIE 75 base and lockring set only. Cog, hub, chain and other parts are not included.
⚠️ This product is designed for use with the SUGINO FIXIE 75 cog. Please confirm cog and hub compatibility before purchase.
⚠️ Please confirm hub thread compatibility with BC1.37 x 24T and BC1.29 x 24T L before installation.
⚠️ Drivetrain installation affects riding safety. Professional installation and lockring inspection are recommended.
