Singlespeeder D Hubs

End of production Singlespeeder hub – We have stopped the production of our singlespeed hub. Our warehouses are also already sold out. Possible remainders can be available at our dealers. Spare parts are of course still available.



The singlespeed is the vinyl record among the bikes : primeval, puristic, stylish. And even exhausting in case you need to justify the retro technology to the ignoramus or to those who rather prefer to change gears secretly. But the real fans appreciate their singlespeeder as the Oldtimer driver its gullwing. For those we build up this antithesis of the miracle wheel: normal rims, normal spokes and our basic front hub. Only the rear hub has been developed extra. Our promise: no stress with the material so that you can keep all your power for biking. Uphill you will need it!



For our hubs we only use standard bearings adjusted for our necessities. This means our bearings have the same width and diameter measurements as standard high precision deep groove ball bearings. Whereas the insides are especially tuned for us. For example, we use a special bearing grease whereby the friction can be reduced, and the lifespan extended. The inside bearing of the freewheel body creates a specialty. The characteristics were individually adapted for the high load experienced by the bearing. To ensure best performance we also adjusted the bearing play exactly for our hubs. Advantage: Standard bearings can be used temporarily, if tune TUNE bearings are not available.
