- Specifically designed for 157 x 12mm Super Boost frames, this has wider hub flanges compared to a standard Pro 4 157mm rear hub, increasing complete wheel stiffness.
- Machined from forged 2014 T6 Aluminium billet
Hope has been producing beautifully crafted CNC’d mountain bike parts for as long as anyone can remember. Their Pro 4 Super Boost rear hub has the same durability as the standard Pro 4 in addition to a wider flange spacing to suit Super Boost 157mm frames. There’s also a decreased percentage dish for more even spoke tension resulting in a stronger stiffer wheel build.
The Pro 4 offers 44 point engagement – every 8° rotation – which is plenty for most mountain biking scenarios. The larger diameter driver bearing lends extra stiffness, and a longer life. Despite the increased dimensions, weight has remained about the same as the previous Pro 2/Pro 3 hubs.
