    Shaft drive is heavier and mechanically less efficient than a chain drive. If weight and high performance aren't big issues, they are ok.

    I've ridden a current model shaft driven Dynamic bike with an 8-speed Shimano internal gear hub and the combination seemed to work but felt rather sluggish.

    Chain-drive is like 98-99% efficient. Shaft-drive is around 60-70%. You're wasting a lot of energy.

    Here is some stuff I put in another forum about mine, a Dynamic/Newport :

    "Here's from someone who owns one.......
    The shaft will never wear out if its greased. Its sooooo overbuilt.
    I cant see it ever needing to be replaced, despite what the guy at Dynamic
    sez. Show me someone with 10K on one to disagree and Ill believe otherwise.
    The problem I have is with the bottom bracket that is underbuilt. That is
    the weak link on my Dynamic/Newport. It requires constant tightening of
    all of its three, whoppingly huge, 2.5 mm screws. There should be at least
    two more and of a larger diameter. If you've ever had your new bike sand blasted
    on the coast of Florida, or tried to ride year 'round in Vermont and want gears
    or need to carry your bike up a flight of stairs and not enjoy grease on your clothes,
    you will understand why some people like them. If you want to make time with
    the local Carbon Fibre, Power Ranger clubbies, it isnt the bike for you "


    As far as efficiency, You can feel a slight difference between the chain ad
    the shaft but I always can keep a constant 20mph with no problem.
    This is FL, though
    -ADVOCACY-☜ Radical VC = Car people on bikes. Just say "NO"
