    Have you given the pinion gear system any consideration?

    What ??
    A Pinion 18 and a Rohloff ......... :laugh:

    When I designed my setup, Pinion drives where new and I had no real data on long term reliability.
    So I didn't really look into them.

    But I can tell you one downside of them is that the weight is in front of the front wheels on a tadpole trike.
    This will reduce the weight and hence the traction on the back wheel.
    How much this will affect a tadpole trike I don't know.
    As thats the limiting factor when hill climbing, once the back wheel starts to slip badly then you get off and push.

    But a Pinion drive would work well in a delta trike for keeping the front wheel down and hence steering on steep hills.

    Luck ........ :biggrin:

    Thanks, I always wondered how they came up with the Max difference between chainrings.
    I must admit that I never gave it much thought But it makes sense the way you put it.

    How long does it take you to change a cassette?
    I fear you may be doing something wrong.

    A lot longer than it takes me to do the annual oil change on a Rohloff, and I can programme oil changes to a winter month to suit my convenience rather than when it becomes necessary due to wear and tear of chain or sprockets.
    On the contrary, I know I am doing something right!

    My take on the main difference between a derailleur and a IHG setup is just the gear shift.
    The derailleur setup is shifted under load and hub gears aren't.
    This means that you keep more momentum uphill more with derailleurs.
    While the ability to shift at stand still is the hub gear advantage.

    YMMV ........... :biggrin:

    I don't know about you but I can change a rear cassette in under 10 minutes.
    Doing an oil change on a Rohloff takes around an hour to do it properly.

    An hour, you are defo doing it wrong. The ride with the cleaning solution only needs to be 2-3 mins before you extract the cleaning mixture then add the new oil. It really doesn't need to take an hour. No need to remove and refit a wheel either as you would when fitting a new cassette.
