BARTIME is a young company from Taiwan, specialized in hubs.

It is fair to say that BARTIME enables unsurpassed wheelset geometry, resulting from their innovative hub construction.  This way the components can be built into one of the stiffest wheelsets.

Due to the hub geometry the rear hub gains a bit of weight; but this mass rotates closely to the centre of the wheelset and does not influence the acceleration so much - opposed to the mass far from centre (dynamic mass), like rims or tires.

Rear hubs boast no less than 5 ceramic-hybrid bearing (hubs are usually built with 4), placed at the very edge of the hub. More bearings, wide positioning and minute tolerance of the 17mm axle all bring to a high stability even under high lateral forces.Bearings provide one of the smoothest axle rotations. They need no maintenance since they are not susceptible to moisture and dust. Hub has protection rings of steel at the aluminium freebody; this prevents the harder cassette material to bite into softer freebody. The "firing" mechanism of the ratchet has 3 pawls with synchronal rings around them thus enhancing rear hub driven effectiveness. BARTIME Ceramic Powerflange RS100 rear hub weighs 250g.
