Product Description

The Praxis Works M30 Thru BSA Bottom Bracket is built to provide a stable, precise fit for select 30 mm MTB cranksets, with its stand-out outboard 6806 bearing layout giving firm support and reducing frame tolerance issues. It uses a forged and machined 7075 T6 aluminium body for strength, with steel bearings for long service, and fits standard BSA threaded MTB frames. This design offers a secure interface for Praxis Lyft Carbon, Race Face Cinch, Rotor REX and Cane Creek eeWings cranksets. Key Features and Benefits: The outboard 6806 bearing layout: This places both cartridge bearings outside the frame shell to remove dependence on internal frame tolerances and c-clips. This improves load stability and alignment over time, which results in smoother rotation and reduced wear. The use of 30mm drive and non-drive bearings: This supports the larger crank spindle diameter with firm radial and axial control. This increases stiffness under pedalling forces, which leads to a more efficient power transfer. Forged and machined 7075 T6 aluminium cups: This high-grade alloy resists deformation and thread damage when installed in BSA shells. This keeps the bottom bracket secure in demanding riding conditions, which maintains consistent crank support. The steel 6806 cartridge bearings: These bearings provide solid durability and resist contamination under MTB use. This extends service life compared with lighter bearing materials, which reduces maintenance needs over time. The BSA threaded frame fit: This thread standard gives a tight mechanical connection that is less prone to creaks than press-fit systems. This creates a more predictable, noise-free fit, which improves long-term user confidence. The crankset-specific M30 Thru interface: This design matches the fit needs of Praxis Lyft Carbon, Race Face Cinch, Rotor REX and Cane Creek eeWings cranksets without adaptors. This removes spacing guesswork, which ensures correct chainline and a stable crank fit. The focus here is on secure crank support for riders who need a strong and stable threaded bottom bracket that avoids the tolerance issues seen in some press-fit designs. The outboard bearing design works with the forged cups to keep the system aligned, while the steel bearings provide the durability needed for regular off-road use. This bottom bracket gives a dependable base for high-end 30 mm MTB cranksets, making it a solid choice for riders who want long-term stability and a precise fit on a BSA frame.
