Robert Axle Project's Lightning Bolt-On axle is a lightweight, low-profile replacement for a stock front thru-axle – precision machined in the USA and finished with a clean bolt head instead of a lever that can snag on obstacles.

Highlights

  • Precision CNC-machined in the USA from 7075 aluminium, hard-anodised for durability
  • Low-profile bolt-on design, no bulky lever to catch on trail obstacles
  • 15mm diameter, M15x1.0 thread pitch
  • Installs or comes out with a standard 6mm hex key, no special tools
  • Backed by Robert Axle Project's lifetime warranty

Compatibility & fit

Thru-axle length isn't the same thing as hub spacing – the axle has to be longer than the hub to reach through the dropouts and thread into the frame or fork, so two bikes with the same hub width can still need different axle lengths. Robert Axle Project lists this as a 15×100mm / 15×110mm (Boost) front thru-axle. This axle is a 15mm diameter, 142mm front axle with a M15x1.0 thread. Confirm your exact frame or fork against Robert Axle Project's online Axle Finder before ordering – a wrong axle can work loose or fall out under load. The Tune workshop can also measure your existing axle and fit the new one.

Robert Axle Project backs this axle with a lifetime warranty to the original purchaser, covering defects in materials and workmanship for as long as you own it. Misuse, improper installation, failure to follow the instructions, normal wear and tear, and crash or accident damage aren't covered, and a claim needs to be reported within 60 days of a defect showing up. 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.
