The two toothed disks of the freewheel system, unlike ratchet freewheels, guarantee that all teeth are always fully in use. With pawl freewheels, however, in the worst case only one pawl can be engaged. This puts extreme loads on the hubs and freewheel bearings. With heavy loads (e.g. up a steep hill), a total failure is usually the result. Only high-quality, double-sealed industrial bearings with a special grease filling are used on Newmen rear hubs. The grease used offers a 25% higher water absorption capacity and a very high bleeding temperature, which protects the bearings from premature wear and corrosion. The 17 mm oversize rear wheel axle is butted on the inside for weight reasons and ensures the best stiffness values. In order to prevent unwanted noise (especially with knife spokes), the J-Bend hubs can of course also be spoked without contact. The high tolerance accuracy of all components is perfectly rounded off by the TA caps. The TA-Caps (Tolerance Adjustment-Caps) are used to compensate for all occurring component and assembly tolerances and guarantee a long and easy running of the bearings or the hubs. Made in Germany.
