    cassettes 11-32t vs. 11-34t

    I would like to buy a new XT cassette to go on a new wheel set.
    What is the difference between a 11-32 v s a 11-34 cassette? Is only the biggest ring in the back bigger for a 11-34? Or are the spreads different.

    Also will I notice a big difference when I use a 11-34? I have a 11-32 LX that came std on my bike.

    Thanks

    Assuming your setup is 9sp:

    11-32 LX combo is: 11, 12, 14, 16, 18, 21, 24, 28, 32
    11-34 XT combo is: 11, 13, 15, 17, 20, 23, 26, 30, 34

    You will notice a small difference if you need an easier gear climbing hills.

    The higher the number translates to a higher cadance necessary to do X mp/h,

    ie if you were on the 34 ring, you need to pedal more RPMs to get X speed, where as for the 32 you need less?

    So for someone such as myself who tends to stay in the middle ring and big ring most of the time the 11-34 equal better choice?

    34t on the rear cassette vs the 32t on the rear cassette will require to have a higher cadence to acheive the same speed. If you do not need a easier climbing gear that there is not need to get that combination. Across the whole combination the 11-34 will require a higher cadence the acheive the same speed.

    Alot of it is personal preference. I use a 2x9 setup in the front on my mtn bike with a 29t &42t , and in the rear i run a 12-27 90% of the time because i like the closeness of the gear combo's. If i know i am going to be climbing super steep terrain or going to be in the mud i will swap out my 12-27 for a 12-32. But very rarely do i use this combo.

    I find that with a standard 32 middle ring with a 11-34 cassette, you really can't use the 32/34 combo because of the high chain angle and you can feel the resistance and the griding as well. I stopped using that combination and to go down to my granny ring every time I needed a smaller gear than the 32/30.

    IMHO the 32/32 works much better ... something to keep in mind if you don't need the granny ring much.

    That said, I still like the 11/34 because you get a 34T on the granny ring!.

    Perfect! Thanks everyone for all the advice. I'll stick with the 11-32T as I do use the middle ring a lot.
