Why isn't there a 14 speed drivetrain yet?

Since the number of speeds in a cassette increases by 1 approcimately every 5-10 years, why not get ahead of the curve, skip 13 speeds, and produce a 14 speed? This is a serious question.

    so we buy the 12 then 13 set ups first, simple economics :D

    There is. Shimano Tourney, 2x7 innit.

    Oh, no, what I meant was, why isn't there a 14 speed cassette?

    Because SRAM, for example, could make shimano and campy look bad by putting out a 14 speed and forcing their hand. I understand the economics of progressively higher speeds in the rear, with fewer in the front, just thought it'd be neat if they skipped 13 since it's unlucky.

    I'm aware, but they weren't being funny enough to get away with dodging the actual question.

    We'll end up with chains the width of a ladies necklace.

    NB: I am not an engineer. I hope however a bicycle is always recognisable as such and as it's been for a century.

    They'll have to make the hub wider otherwise the spokes will be vertical :D

    I think this thread is too important for me to allow you to jeopardise it.

    The more speed you have, the closer the ratios get. The closer they get, the more you feel compelled to change gear. The more you do, the quicker they wear... the quicker they do, the sooner you need newer ones...

    anything above 11 speed for me is pointless. of course in 2013 I said that about 10 speed. 11 speed wears quicker than 10 speed.

    so that's that then. tourney FTW.

    I thought 11 and 10sp chains wear the same rate.

    I thought the more gears, the less time in any given gear, so slower wear?

    I have a 12 speed groupset 105 golden arrow from 198x. Very close ratios too 52/42 and 13-18T.

    14 speed will require wider rear traingle which creates chainline issue. 13 speed from rotors has a disc brake hub with 17/33mm flange spacing (its a disc brake hub). That means the end of thin spokes like CX-rays for wheel building. 12 speed the way campagnolo has done it is good. A 13th sprocket would therefore need to be 36T and then you heading toward 1x ratios.

    14 speed is for 1x and you would have a 10-40T cassette, something like 10-11-12-14-16-18-20-22-25-28-31-34-36-40T, or 11-12-13-15-17-19-21-23-25-28-31-34-37-40 There simply is not enough space inside the rear triangle for a good wheel and 14T with close ratios.

    14T wide ratio will still require narrower sprocket spacings and that an engineering challange.

    Surprising number of broken chains in CX racing these days. Unheard of in days gone by. Could it be anything to do with little or no pin protrusion beyond the outer plate? Less and less mechanical engagement as chains get narrower. Even I have broken a couple of 11 speed chains and I put out as much power as an average grasshopper.

    14 speed is disaster waiting to happen.

    That's why campagnolo 12 speed rear derailleurs move forward as you move down the cassette to increase chain engagement and reduce wear.

    is that right? pretty neat stuff and a nice touch.
