The Shimano Alfine is a top component group for sporty and elegant cycling. Premium quality, style, adaptability, and effortless operation are the hallmarks of the Shimano Alfine. The tidy appearance and wide gear range of this eight-speed hub gear system provide real momentum to the bike. The Shimano Alfine FC-S501 comes with the SM-BB4600 bottom bracket.

The two-piece design integrates the crank arm and bottom bracket, which increases stiffness and reduces weight. The axle bearings are spaced further apart, enhancing stiffness and effectively transferring the rider's power. Precision bearings ensure low maintenance and simplified assembly.
