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.

Fast engagement, and reliable, there's no better way to describe the Hope 4 Boost. There's no need in investing in a hub twice as expensive only to have a slight increase in engagement. The quality of the build is high quality and comes in an assortment of colors that will add flair to your rig.
With Boost Rear as an option, these will work perfectly with the newer boost specs.
I consider this money well spent and will look to Hope for my next upgrade
