HOPE rear wheel 28" RD40 Carbon | Pro 5 Straightpull Center Lock | 12x142 mm | black
Install, ride and forget about it. Hope components have always been synonymous with durability and robustness. The latest generation of their wheels is in no way inferior. You can really let it rip with them and even the occasional riding mistake will be forgiven.
The RD40 rims in particular contribute to their indestructibility. Made from high-quality UD carbon fibers in monocoque construction, they can accommodate tires up to 40 mm wide with their large inner width of 19 mm. This provides additional grip and comfort. The 40 mm high sidewall generates excellent aerodynamics and ensures a striking appearance. The rim flange has been specially reinforced to withstand even heavy punctures without damage, and the RD40 can of course be converted for tubeless use. A set of rim tape and valve is already included in the scope of delivery.
The Pro 5 hubs from the English cult manufacturer from Barnoldswick are at the center. The experience gained from 30 years of designing and manufacturing high-quality drive elements has been incorporated into their development with the aim of improving proven technology in order to meet the demands of current and future bicycle technology.
The design of the rear hub differs significantly from its predecessor, with an enlarged body that generates more rigidity without increasing the weight. This is noticeable above all in a much more direct ride. At the same time, the diameter of the spoke flange has been increased, making it easier to build very stable wheels.
The highlight of the rear wheel hub is the new 6-pawl freehub system in offset design, which is characterized by the fact that three of the six pawls are always engaged when riding in order to distribute the load evenly. In addition, the freehub gearing has been increased from 44 (Pro 4) to 54 teeth, resulting in a total of 108 engagement points and a low free travel of just 3.33°. In addition, some material has been removed from the pawl springs, slightly reducing the spring force and lowering their resistance. Hope has thus achieved the right balance between smooth running and durability with the Pro 5.
The hub can withstand negative external influences for a long time, thanks to the high-quality anodization and the very well-sealed stainless steel industrial bearings. Should the ravages of time take their toll on the hub, it can be dismantled and serviced with little effort. It can also be easily converted to a different hub standard.
The connection between the rim and hub is provided by Sapim's CX-Ray spokes, with which the Belgians have succeeded in developing an exceptional spoke. In addition to its low weight, it has an exceptional load capacity and flexibility. This also results in a wide range of applications. Whether road cyclists or mountain bikers, everyone benefits from these positive characteristics. In addition, the flattened middle section ensures excellent aerodynamics. The high material quality enables the construction of stable wheels and guarantees a long service life.
