    Maybe a b-bolt. Maybe not. There's really only one way to know. Just do it. Your RD shouldn't have any problems.

    I once installed an 11-34 cassette, where I had been running an 11-32, without realizing it was an 11-34. I never even noticed I had done it until I removed the cassette for something else several thousand miles later and noticed it was an 11-34.

    Well, ending the geographic lock you guys have, the change may be trivial and it may not be. Depending on the rear derailleur you have, the larger cog may require a b-screw adjustment or may not clear at all. For example if you have a road rd the 32 may be very marginal and the 34 puts it over the edge. If you have an MTB rd, the 34 will likely work with no problems.

    Also chain length has to be considered. If your current chain will JUST allow big-big, you will need one a couple of links longer. In fact, if you are installing a new cassette, a new chain is a good idea along with it.

    actually thats why im replacing the cassette, the entire drive train was new except the cassette and the chain slips in 3 of the cogs when i pedal hard, after some research the common theme was that i was using a worn out cassette with a new chain... easy fix imho

    OK, but if you go to a new cassette with a larger big cog, be sure the chain is long enough to shift into big-big. That's an important safeguard.

    Probably because the weather outside sucks today.

    I set my chains up with that in mind but in many years of riding I've never had it be a thing. Especially from a safety standpoint. I never try to get into a big/big gear.
