Hope Pro 4 148mm Boost Rear Hub

Hope Pro 4 148mm Boost Rear 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, and also allow more interior room for a bigger ratcheting ring, now biting with 44 teeth for a noticeable improvement in engagement speed, equating to snappier accelerations and an overall more responsive ride.

Additionally, the freehub body has been lengthened to accommodate the ever so popular 11-speed cassettes from Shimano and SRAM. Knowing that none of this 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 wide-design 148mm Boost employs dedicated hub shells built with broader spoke flange spacing that play nicely with Hopes new Boost specific chainrings that feature 3mm offsets to maintain a proper chainline.

Features:

  • 4 Pawl Ratchet with 44 tooth engagement (8.2 deg)
  • Sealed Stainless Steel cartridge bearings for durability
  • Machined from forged 2014 T6 aluminum billet keeps weight low
  • Boost 148mm hub width and designed to take a 12mm thru axle
  • Standard 6 bolt disc fitting
  • Larger spoke flange to enable stiffer wheel builds
  • Unsurpassed reliability
  • Weight 311g

Specifications:

  • Designed specifically to suit a frame with a Boost 148x12 rear end
  • Aluminium or steel freehub body options
  • Available in 28, 32 and 36 hole drillings
  • Supplied with freehubs to suit 10/11spd Shimano or Sram XD cassette
  • Weight: 311g for 36 hole version with a Shimano 11spd alloy freehub body
  • Hub flanges move outboard 3mm compared to standard Pro 4 rear hub to increase complete wheel stiffness
  • **Note**148mm hub uses a different wider hub shell and axle compared to standard 135mm Pro 4 rear hub

Good so Far
I have three of these now. I needed a reliable, strong hub for all-mountain riding that was affordable. These fit the bill. Hopefully they hold up; I am a big dude and ride very aggressively. Nothing but good results so far. My oldest one is only 4 months, but no issues and still running smooth with several hundred miles on it. 44 points of engagement isn't crazy fast, but I find that the feeling between engagement improvements decreases dramatically after you get under 10 degrees (36 points). As for boost spacing, they say a boost hub on a 29er should feel like a standard 142mm on a 27.5, stiffness-wise; I highly disagree. I have Stans Flows built up on this hub on a SC Nomad (142x12, 27.5") and a YT Jeffsy (148 boost, 29er). Both 32 holes. The wheel on the Nomad feels rock-solid, even though the bike sees bigger jumps and gnarlier rocks. I can feel the wheel on the Jeffsy flexing around like crazy and the rim has had to be trued out twice in 4 months of riding. Going to carbon wheels with 36 spokes for the Jeffsy 29er, despite boost. (I weight 230lbs without gear, ride hard all-mountain).

will the boost rear hub with XD driver fit an eagle cassette?
A shopper on Jun 23, 2017
BEST ANSWER: Yes, I have the boost with XD and a Xo1 Eagle cassette on it- works great.
Can the end caps be replace with QR caps on this?
A shopper on May 5, 2017
BEST ANSWER: This hub will not work with 135mm QR frames because the "boost" standard moves the rotor position further outboard. The Pro4 non-boost (135/142mm) hub is what you'll need.
