Product Reviews
Loading reviews…
Switching between the old worn Shimano and B-Twin reveals the new to have a much noisier freewheel and a very clunky gear change by comparison.
Der Schraubkranz ist aus Stahl gefertigt und verfügt über einen integrierten Freilauf, der gedichtet ist und somit auch wartungsfrei. Die Übersetzung bzw. die Abstufung ist gut geeignet fürs MTB oder Crossrad, wenn überwiegend im flacheren Terrain gefahren wird. Vor der Montage sollte das Schraubgewinde eingefettet werden, um sicherzustellen, dass sich nach längerer Zeit und Benutzung der Kranz nicht festsetzt und ein Demontieren oft nur unter erheblichem Kraftaufwand möglich ist. Bei Shimano ist das kleinste Ritzel immer mit 14 Zähnen gefertigt aber z.B. von SunRace gibt es auch ein Modell mit 13 Zähnen.
Il prodotto e' arrivato nei tempi stabiliti, sembra di ottima fattura originale marchiato, montato e tutto assemblato con altre parti cambiate quali, Catena KMC, Cassetta questa in questione va bene. Poi la guarnitura ! Tutto e stato conforme. Ordine compreso. (Le recensioni spesso non vengono pubblicate anche se in regola) !
