Hi, can anyone tell me what the differences are between the shimano alfine hubs? are the s500 and s501 hubs the same internally?
thanks,
Jim.

    I don't know the tech details, but I believe the 501 had some sort of clutch upgrade, making shifts smoother and quicker.

    Having said that, the s500 on my Pylon8 is crisp after 9 months (~1500 miles) use.

    Currently awaiting an 18T sprocket from On-One, to replace the default 19T, to give me a top speed boost going downhill in 8th and also give the bike a more disirable 5th and 6th (~52/61 gear inches --> ~58/65)

    according to a rely on hubstripping (the place for everything hub-gear related)

    "They added an additional roller clutch (on the 501) in place of a ratchet assembly. That makes the 501 completely ratchet free and improves the quietness and smoothness of the internal assembly."
