NONPLUS COMPONENTS rear hub Primaro SP | Center Lock black 12x142 mm | Freewheel SRAM XDR
Three decades of experience in the development and production of hubs have left their mark, albeit a "very light" one. Over the years, Christian Jenny, Head of Development at NONPLUS COMPONENTS, has accumulated an immense amount of specialist and practical knowledge, which led to the production of the company's first prototypes in 2016 after finding an investor. A short time later, in 2018, NON+ was registered as a trademark. Since then, the wheels have not stood still at one of the most innovative think tanks for bike components in Germany. New concepts are constantly being developed and patents applied for in order to set new standards in the future.
After the NON+ MTB hubs had made a name for themselves among lightweight builders worldwide, the decision was made to transfer the unique technical properties into an ultra-light hub pair with center-lock brake disc mount for road and gravel use.With their slim hub bodies for straight-pull spokes, the NON+ Primaro SP hubs fit perfectly into the overall look of modern road bikes. Their matt black anodized finish not only looks good, it also protects the hub bodies from corrosion.
Two large bearings support the hub body on a 17 mm axle, two further bearings support the freewheel and the micro-gap end caps keep dirt and water away from the inside of the hub. On the opposite side, the patented freehub mechanism is concealed inside. The unique bevel gearing has a contact surface that is approx. 400 % larger than that of conventional spur gears and therefore enables maximum power transmission with minimum wear. Together with the hard anodized surface, the special, very elaborately manufactured back of the tooth ensures low abrasion and thus additionally increases the service life. The 45-fold toothing results in a maximum free travel of 8°. This means you have immediate propulsion when you need it in difficult passages, for example, and don't lose any valuable time when sprinting to the finish.
The pair of hubs weigh just 203 grams on the scales, putting them on a par with the lightest hubs on the market. Despite their extremely low weight, the hubs are approved for a system weight of up to 120 kg in road bike use.
Self-adjusting bearing play
Thanks to high-precision manufacturing and perfect quality control, the hubs do not require an adjustment ring for the bearing play. This means you always have a perfectly adjusted hub with smooth, easy running.
Precision and quality
The elimination of disruptive factors such as flex, vacuum effect, spoke tear-out and tolerances through the highest precision in material selection, manufacturing process and quality assurance. All this enables a guarantee period of 4 years.
NONPLUS tapered toothing
The unique freewheel mechanism of the NONPLUS hubs has approx. 400% more contact surface than conventional systems and enables maximum power transmission with minimum wear. This represents a major advantage over conventional ratchet systems, as the forces are transmitted by the toothed pulleys at certain points rather than over a large area. Special, very elaborately manufactured tooth backs reduce abrasion many times over, while a hard anodization ensures a long service life.
Non Vacuum Effect
A unique venting system prevents the formation of negative pressure due to temperature fluctuations in the hub. As a result, no water is sucked through the ball bearings, which ensures a significantly longer service life and noticeably smoother running of the bearings.
High-speed bearings
The resistance of the bearings has been increased in favor of maximum speed in dry conditions - however, higher wear is to be expected in adverse conditions.
Special sealing
Micro-gap end caps improve the sealing of the individual hub components.
E-bike compatible
Although the hub does not weigh 141g, it is still suitable for light e-bikes.
