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 57mm 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.
|Drive Shell Material:||Aluminum|
