    SRAM 11 speeds climbing

    I bought a 29in hardtail, 20 pounds(used) that i like, it has a SRAM 11 speeds 32 teeth with 10/42, for easier climbs with a packsack or after 3 hrs of riding may i get a 28 teeth, i have 4 bolts 96mm BCD, may i get a cassette with 46 teeth or should i make the move to a 12 speeds, hopefully turning a bike i like into one i really like, thanks, a new fat/mountain biker
    ps. please give me a dollars idea for your suggestion

    I've seen 28T with 64bcd (Northshore Billet), not sure about 67bcd, what crank is that?

    It all depends on your area.
    I can get away with my 34T chainring and SRAMs 11-42 cassette,
    But some races, Like Whiskey that 50T or a 2x would have been nice due to my fitness level.

    But ALL my SRAM drivetrain is going away and being replaced with Shimano which offers a 11-46 cassette
    Too Many .

    Might that be an x-sync crank with removable spider? If so you can get a smaller direct mount ring.
    Do the math.

    Need to figure out what top speed you need.... Most trail mountain biking is less than 25mph and also depends on fitness level. I would do the 28, would give you plenty of granny for climbs but lose some flat out speed. Look at a gear calculator to see exactly what you gain and lose.

    SunRace is actually supposed to be releasing an 11-50 11spd cassette shortly here, may be worthwhile.

    Thank you for the info, i will start with the chainring change use my cassette and chain and have that option in some months when they need to be changed if my derailleur will permit it

    The least expensive way is the chainring and they are easy to interchange if needed. No need to replace working kit, better to replace when broke or at the end of their service life. I'm using a Absolute Black oval 26 w/ 11-36 shimano and getting to point of replacing with a 30T.

    I just made the switch from my XO1 32 t to the North Shore 28 and what a nice difference for the steep stuff. They are on Ebay now for $37 shipped and worth every penny.
