Hope Pro 4 Boost Front Hub

Hope Pro hubs have gained a reputation for being exceptionally versatile, as they can be adapted to just about any axle size and cassette arrangement. Holding true to tradition and building upon the charms of the Pro 2 series hubs, Hope introduces their Pro 4 series hubs which come to us refined with larger flange diameters to improve wheel stiffness. Knowing that none of that would mean anything if the hubs innards didn't hold up to the rigors of riding, Hope didn't hesitate to use a bigger inboard freehub body bearing to improve durability. All of these new features come with little-to-no change in weight over the Pro 2 hubs.

The Pro 4 Boost front hub can be modified between 9mm quick-release or 12, 15, or 20mm thru-axles.

Features:

  • Boost 110x15 compatible
  • Sealed Stainless Steel cartridge bearings for durability
  • Hub shell machined from forged aluminum billet to keep weight low
  • Standard 6 bolt disc fitting
  • Larger spoke flange to enable stiffer wheel builds

Specifications:

  • Designed specifically for use with Boost 110x15 forks only
  • 28, 32 and 36 hole drilling options available
  • 6 colour options to choose from
  • Standard ISO 6 bolt rotor fitting
  • Published Weight: 188g for 32h option
  • Hub flanges are moved outboard 5mm compared to the standard 100m front hub to increase wheel stiffness
  • **Note**Boost 110mm front hub uses a different, wider hub body compared to the standard 100mm Pro 4 front hub
