Mounting structure of the rear wheel of a bicycle with a wheel hub consists of a clamping node (20) on the left fork (16) adjacent to the wheel hub (17) and a cassette node (21) on the right fork (16) adjacent to the hub (17). ) of the wheel, wherein a shaft (19) with lips is passed through the clamping node (20), the wheel hub (17) and the cassette node (21). The clamping node (20) is formed by a bearing housing (10) which is firmly connected to the fork (16). A bearing (9) is secured in the bearing housing (10) against axial movement by a ring (8). A clamping hub (4) with two fixed carriers (7) fixed and symmetrically mounted is mounted in the bearing (9). A flange (3) is fastened to the clamping hub (4) by means of a thread, to which a brake disc (1) is fastened by means of screws (2). At the end of the clamping hub (4), an eccentric lever (5) is fastened by means of a pin (6). The cassette node (21) is formed by a bearing housing (10) which is firmly connected to the fork (16). A bearing (9) is mounted in the bearing housing (10), secured against axial movement by a ring (8). In the bearing (9) there is a cassette hub (11) with two fixed carriers (7) fixed and symmetrically fixed. A cassette (15) with at least one sprocket is mounted on the cassette hub (11) by means of a thread, in which a spring (14) is mounted. Two long carriers (18) are fixedly and symmetrically mounted in the wheel hub (17). The shaft (19) with springs is terminated on the side of the cassette node (21) by a thread with a ring nut (12) and a lock nut (13) and on the side of the clamping node (20) fastened in the assembly by an eccentric lever (5). Konštrukcia upevnenia zadného kolesa bicykla s nábojom kolesa pozostáva z upínacieho uzla (20) na ľavej vidlici (16), priliehajúceho k náboju (17) kolesa, a kazetového uzla (21) na pravej vidlici (16), priliehajúceho k náboju (17) kolesa, pričom cez upínací uzol (20), náboj (17) kolesa a kazetový uzol (21) je prevlečený hriadeľ (19) s perami. Upínací uzol (20) je tvorený ložiskovým domčekom (10), ktorý je pevne spojený s vidlicou (16). V ložiskovom domčeku (10) je uložené ložisko (9) zabezpečené proti axiálnemu pohybu poistným krúžkom (8). V ložisku (9) je uložený upínací náboj (4) s dvoma pevne a symetricky upevnenými krátkymi unášačmi (7). Na upínacom náboji (4) je pomocou závitu upevnená príruba (3), na ktorú je pomocou skrutiek (2) upevnený brzdový kotúč (1). Na konci upínacieho náboja (4) je pomocou čapu (6) upevnená excentrická páka (5). Kazetový uzol (21) je tvorený ložiskovým domčekom (10), ktorý je pevne spojený s vidlicou (16). V ložiskovom domčeku (10) je uložené ložisko (9), zabezpečené proti axiálnemu pohybu poistným krúžkom (8). V ložisku (9) je kazetový náboj (11) s dvoma pevne a symetricky upevnenými krátkymi unášačmi (7). Na kazetovom náboji (11) je pomocou závitu upevnená kazeta (15) aspoň s jedným reťazovým kolesom, v ktorej je uložená pružina (14). V náboji (17) kolesa sú pevne a symetricky upevnené dva dlhé unášače (18). Hriadeľ (19) s perami je na strane kazetového uzla (21) ukončený závitom s kruhovou maticou (12) a kontramaticou (13) a na strane upínacieho uzla (20) upevnený v montážnom celku excentrickou pákou (5).
