R2BIKE wheelset 28" Disc GRV | Hope Road Center Lock hubs | Newmen Gravel Carbon rims
Area of application: Gravel GRV
This lightweight yet stable wheelset is the first choice for dedicated gravel or cross bikers. The well-balanced selection of components guarantees high reliability and a long service life.
Hubs
At the center of the wheelset are the Pro 5 hubs from the English cult manufacturer from Barnoldswick. 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 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 significantly 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, which slightly reduces the spring force and lowers 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.
Rims
Like all Newmen carbon rims, the Advanced SL X.R.25 impresses with its first-class mechanical properties and very low weight and is the ideal basis for a lightweight gravel wheelset.
The hookless design makes it ideal for tubeless use, while the significantly reinforced rim flange is better able to withstand possible punctures and allows riding with low air pressure. To avoid weak points and increase durability, the spoke holes were drilled in a special process without damaging the structure of the carbon fibres. The generous inner width for gravel rims also gives wide tires a reliable grip. The slightly outward-positioned sidewalls make the shape of the tire rounder, resulting in significantly better cornering grip and increased safety.
Wheel construction at R2-Bike
Our wheels are assembled entirely by hand by our wheel builders. During the entire assembly process, great importance is attached to ensuring that not only the concentricity is correct, but also that the spoke tension is as even as possible. This special care allows us to give the first owner a lifetime guarantee against spoke breakage, as long as it was not caused by force.
The following services are also included for first-time buyers:
You get a universal wheel bag for all common sizes included.
You will receive a spare spoke with nipple in all required spoke lengths so that you can repair the wheel quickly after an accident.
Within 2 years of purchase, you will receive a free initial inspection of the wheel, during which the resulting work is completely free of charge. Only shipping costs are incurred.
You get a crash replacement promise: If your wheel is damaged within 2 years of purchase due to force majeure, we will rebuild it once. We grant a 100% discount on all labor costs and only charge for the material.
