A Robert Axle Project Lightning Bolt-On axle replaces the proprietary NAILD rear thru-axle with a simpler, more durable bolt-on design, for Marin and Polygon bikes built with the NAILD system at a 12x148 rear hub.

Highlights

  • Purpose-built for the NAILD thru-axle system, 12x148 rear hub
  • Includes a replacement M12x1.0 nut in place of the NAILD nut
  • 7075 aluminium shaft, hard-anodised
  • Installs and removes with a standard 6mm hex wrench

Reversible

No permanent modification is made to the bike — the stock NAILD axle and nut can be refitted at any time.

Compatibility & fit

This axle is built for the NAILD system at a 12x148 rear hub and is not a generic 12mm axle — it will not fit other thru-axle systems. A 12x142 version is also available as a separate listing for the narrower hub spacing. Bring your bike to the Tune Cycles workshop and we'll check fit before installing.

Robert Axle Project warrants its axles to be free from defects in material and workmanship for the lifetime of the original purchaser's ownership, covering manufacturing faults only — not misuse, crashes, incorrect installation or normal wear and tear. For warranty support, return the product to Tune Cycles and we'll manage the claim with Robert Axle Project's Australian distributor. This is in addition to your rights under the Australian Consumer Law, so keep your proof of purchase.
