    I'm thinking about binnin the large chainwheel and getting a bash guard instead.

    I probably catch the chainwheel more times than I use it.

    Then stick on a hammershmidt as well - bodging it to work with a triple, of course :lol:
    I reckon you'd be thinking so hard about how to change gears, you'd end up crashing all the time :lol:

    (drum role)
    8264 gears!now that would be the one!!!!! imagine trying to choose!
    "now, do i need 6420, or 905 for this climb?" "hay mate, what gear are you in?" "um, 7437"

    someone post the link to the continuous gearing gearbox.

    Infinite number of gears, bish bash bosh I win... limited range though.

    that already exists? unbelivebly i was drawing up tech diagrams of something working on what must be a similar principle just 2 days ago, i was thinking about getting a prorotype machined up! it would be a sealed unit attatched to the freehub and mech hanger in place of a mech to giv a Bolt-on gearbox effect.

    clever, probably could work.


    the one i saw is a gearbox that fits in the BB area.

    With a typical 3 x 9 there is 14 different ratios, if the large chainring is removed it loses 2 ratios.

    Changing the middle ring to a 36 gives back 1 ratio so it ends up back to 13.

    With a triple you get on the granny 3 ratios, then 9 on the middle and 2 on the outer

    With a double and 36 middle it's 4 and 9.

    Also need to look at the spread - I run a triple because I use both the 44/11 and 22/30.

    Now if mechs could jump 22 teeth at the front ;-)

    Brilliant.

    But unless this would get in the way of the GT thing you were talking about (never heard of it myself), how about this..

    hondas gearbox from their old dh bike (if anyone remembers 2004 - I think)

    So how many gears was in that thing?

    It was a Suntour G Boxx I think?

    very similar to the gt thing.
    iv just remembered the Diamond back sabbath, it has the new Suntour g-box with 9 gears.....so....
    9x2x4x11x14=
    11088 gears!!!!!1

    I imagine gear 1 would be so low that you would have to turn the pedals a full 10 times before the wheel moved.

    And gear 11088 would be so high you could just jump up and down on one pedal all day and it wouldn't budge.


    However, if anyone makes this bike, please take pictures. Then get a life :D

    Well the new version will have 16 gears! So that is

    19712!

    Assuming you can actually bodge a quad chainset onto a Hammerscmidt!

    Oh no - one of my gears is skipping..













    BUT WHICH ONE???? :shock: :shock:



    Find out, next year (after you've had enough time to go through every single gear)



    You'd also have so many cables that if you weren't careful, cable rub would just turn your frame to dust within a few rides. And you would definitely need some H bars for the levers, maybe stick some downtube shifters on as well.

    I reckon you might have so many gear cables, they'd weigh more than a normal bike :lol:

    3 bikes and 75gears total, but I only use about 4 on each bike very often. Plus the phase 24 speed or 27 speed is misleading as others have pointed out as some ratios will be the same ans there's a few combinations you should never use (e.g. Granny front and smalllest cog back)

    So, on a 9-speed, triple chainring set up, would this be more or less correct with regards to useable gears...

    Granny Ring = Use bottom 5 gears?
    Middle Ring = All 9 gears (or middle 7)?
    Large Ring = Top 5 gears?

    Yes (ish). Have a look in the FAQ, I put a guide in there.

    Two bikes, 28 gears between them.

    But then, I am fabulously wealthy.
    Or I was until I bought two Rohloff hubs. :?

    Unfortunately, my bike's an atheist.

    I have 21 on my Orange ST4, the xtr cassette kinda exploded a bit and I lost the 32t cog..... just set the stop screws and viola 8sp cass converted to 7! Saved a bit of weight to boot, hardly used that wimpy 32t anyway......
