Factory OEM | Bolt-On | 174.5mm | M12 × 1.0 | S220200002

The Specialized Factory Replacement 12x148mm Boost Rear Thru-Axle is a genuine OEM bolt-on axle used across a wide range of Specialized mountain and Turbo e-bike platforms.

Featuring a minimal-taper design and 6mm internal hex interface, this axle provides a clean, secure installation while maintaining the correct factory rear hub and frame interface.

Because Specialized uses different axle lengths and thread pitches across bikes that may all share 12x148 Boost spacing, correct dimensions are critical. S220200002 measures 174.5mm overall with an M12 × 1.0 thread pitch.

Critical Fitment Information

Do not select this axle based on 12x148 Boost spacing alone.

For correct fitment, verify these three specifications against the original axle:

• Hub spacing: 12x148mm Boost
• Overall axle length: 174.5mm
• Thread pitch: M12 × 1.0

Specialized uses different axle lengths and thread pitches across bikes that share the same 148mm Boost hub spacing.

Compatibility Notes

• For 12x148mm Boost rear ends only.
• Not compatible with 12x142mm or 12x157mm rear spacing.
• Bolt-on design requires a 6mm Allen key.
• Always follow the torque specification provided for your specific Specialized frame.
• If your existing axle does not measure approximately 174.5mm or does not use an M12 × 1.0 thread, do not assume compatibility.
• Verify MPN S220200002 whenever possible before ordering.

Why Choose a Genuine Specialized Thru-Axle?

A rear thru-axle must match the frame's diameter, overall length, and thread pitch precisely. A generic 12x148 Boost axle can have the correct hub spacing while still using an incompatible thread or length.

Genuine Specialized S220200002 provides the original 174.5mm / M12 × 1.0 configuration specified for compatible Specialized frames, making it the correct OEM solution for replacing a lost, damaged, or worn original axle.
