Fat Bike Crank Spindle - 29mm x 164mm

5Dev Fat Bike Crank Spindle (29mm x 164mm) is a precision replacement/fit-tuning spindle built specifically for 5DEV cranks, designed to match SRAM DUB (28.99mm) and 5DEV 29mm bottom bracket standards. CNC-machined from premium 7075 aluminum and finished with a hard-anodized surface, it targets clean bearing interfaces, consistent alignment, and long-term durability in high-load fat bike use.

• 29mm x 164mm fat bike spindle length - Supports wider fat bike spacing needs and helps achieve an appropriate Q-factor and chainline when paired with the correct crank/frame setup
• SRAM DUB / 5DEV 29mm BB compatibility - Sized for SRAM DUB 28.99mm and 5DEV 29mm bottom brackets for straightforward fitment
• CNC-machined 7075 aluminum - High strength-to-weight material choice for a stiff crank interface without unnecessary mass
• Hard-anodized surface - Improves wear resistance at bearing contact areas and helps reduce corrosion in wet, abrasive conditions
• 5DEV-crank specific - Only compatible with 5DEV cranks for proper interface and safe, correct installation
• Quick swap for re-builds or frame changes - Practical option for moving a 5DEV crank between bikes or reconfiguring a drivetrain without replacing the entire crankset
