15mm Axle Adapter for RockShox Boxxer V2 (2019 – Present) Built for Real Performance

Looking for a 15mm axle adapter for the RockShox Boxxer V2 that gives you real choice  without compromising strength?
The Fox40 V2 Adapter System is a fully engineered performance solution for riders who want flexibility, precision, and downhill-level reliability.

This system allows you to install a 15×110 mm Boost front wheel into a 20×110 mm RockShox Boxxer fork (2019–present) using separate CNC-machined adapter components and your axle of choice. (In this Kit the Hell Pin Axle is included)

Two Ways to Run It  One Performance Standard

Option 1: Freaky Nuts Hell Pin (Recommended)

Pair the V2 adapter set with the Freaky Nuts Hell Pin — a solid (non-hollow) 15 mm axle, CNC-machined from 7075 aircraft-grade aluminum.

Why Hell Pin:

• Maximum torsional stiffness

• Direct steering feel

• Zero flex under braking and hard impacts

This is the strongest configuration available.

Option 2: Use Your Preferred 15mm Axle

The V2 adapter set is also available without axle, making it fully compatible with hollow axles such as the 15mm RockShox Stealth Maxle Thru Axle or any standard equal to this.

Ideal if:

• You prefer a hollow axle

• You already run a Stealth Maxle

• You want modular flexibility

Strength where it matters, choice where you want it.

Precision CNC Machining

All adapter components are CNC-machined with extreme precision for a perfect interface with the RockShox Boxxer V2 fork. The adapters seat cleanly, lock securely, and remain silent — no rattling, no play.

Installation is straightforward:

• Install with a standard Allen key

• No special tools required

• Everything else on the fork remains unchanged
