    22-42 cranksets?

    22-32-42 is a common size for mountain cranksets. Is there a way to go 2xN by just dropping the 32-tooth ring? You'd keep both the low 22-32+ granny and the fast 42-11 gears that way. Maybe I missed something, but why isn't there a 22-42 crankset around?

    Hard to shift to the bigger ring ?
    No sweet spots ?
    Next trend ?

    Front derailleurs are not designed to handle that much of a drop between chainrings, most doubles are 14t max (ie 22/36 or 28/42)

    most of us with that initial triple-ring setup have gone to 11-36, as it is the best compromise- good shifting and good enough range of gears. I tried moving my 42t gear to the middle position- you have to be very deliberate with your upshifts- it is no where near as smooth as 22 to 36. Also, you may have frame issues with that large of a chainring in the middle position. 36t ring has worked fine enough for me for at least the last 10 years- not worth using a 42t to me...

    mtnbiker72 hits the nail right on the head!

    For example, my present 2x9 setup has 22/36 chainrings (ie. 14T difference). While FD downshifts occur more-or-less instantaneously, I do find that FD upshifts (ie. 14->36T) can be a little ponderous sometimes. That's why I'd suggest that a 14-15T difference is close to the practical limit for reliable upshifting.

    Hey, quick question about gearing. I, personally, am considering changing my 3x10 to a 2x10. Gearing with the triple is 42-32-24 with an 11-36 cassette. I'm wanting to get an XT 2x10, but the closest gearing to my current granny is a 39-26 crank. If I switch this, will I notice it being harder to pedal in my granny with the chain ring going up two teeth, from the 24 to the 26? I don't want to lose my climbing ability. Thanks.

    your answer is here Sheldon Brown's Bicycle Gear Calculator .From 24 to 26, 2 teeth diff/24 t ring= 8.33percent harder to climb with a 26t ring. So, yes, on a difficult climb, you may notice that difference.

    Thanks for the info and the website. I'll definitely consider doing that.
