Race Face's Vault J-Bend front hub in a 28 hole drilling, for 15x110 Boost forks. It's the same oversized, 6-bolt Vault front hub, set up for a 28-spoke build.

Highlights

  • J414 front hub for 15x110 Boost thru-axle forks
  • 28 spoke holes for J-bend spokes
  • ISO 6-bolt disc rotor mount
  • Oversized hub shell adds stiffness and stability
  • End caps come off by hand for bearing service
  • Black

Built for custom wheels

The Vault is Race Face's hub of choice for custom wheel builds. The J414 front runs 6805 cartridge bearings inside an oversized shell, and the end caps pull off by hand for bearing service. Alternative J414 end caps (15x110 Boost Torque Cap and 20x110 Boost) are available separately.

Wheel building notes

Race Face sets a maximum spoke tension of 122 kgf at the hub, and radial or 1-cross lacing isn't permitted on Vault disc hubs. Build it into a rim with the same hole count and evenly spaced (not paired) spoke holes. Use 10mm-long rotor bolts and don't exceed 6.5 Nm at the hub's rotor bolt holes.

Compatibility & fit

Fits forks with a 15x110 Boost thru-axle as supplied. Pair it with a 28 hole rim; Race Face requires the rim hole count to match the hub. Our Sydney workshop can build this hub into a custom wheel; wheel building is a separate workshop service and isn't included.

Race Face covers this hub under its Lifetime Warranty, crashes included: a riding crash or a failure during the product's expected usable life is covered. It doesn't cover normal wear and tear (hub bearings, for example), intentional damage, or improper installation or repairs. For warranty support, return the product to Tune Cycles and we'll manage the claim with Ride Fox Australia, Race Face's Australian distributor.
