    Swapping SRAM APEX 11-32t cassette for something more conventional

    What steps would I have to take to swap out my cassette to something with a more conventional gear spacing. I like the way Apex performs but I live in South-Eastern Michigan and the climbs here a nothing that extreme. Could I just swap out the rear cassette and been done with it or does the rear derailleur need to be adjusted? Just curious. Apparently I have the Wifli RD which has a max 32t capacity. I'd like to throw on like an 11-28 or something. Thanks in advance

    Throw a new cassette on, and shorten the chain.
    2010 Specialized Secteur Elite with the RBR not-approved Mavic Ksyrium Elite wheelset
    2009 Specialized Rockhopper Comp 29er upgraded to SRAM X9 with 1x10 and Stan's Arch EX rims and tubeless.
    2013 Cannondale CAADX-6 Tiagra with 9-speed SLX RD to run 11-32T cassette and Stan's Alpha 400 rims and tubeless
    and
    Some Burton snowboard setups, one with stiff ol' Camber and one with Rocker-Camber-Rocker

    Just swap it out, check the shifting and you're good to go. I just did the same thing, swapped the 11-32 on my Giant to a 12-27. I had to adjust the cable tension for the RD by 1/4 click but that was it.

    Swapping SRAM APEX 11-32t cassette for something more conventional

    Note that you don't have to shorten the chain, as it will be longer than it needs to be but it is not too long. I use an 11-32 and 11-28 on my cross bike and like to switch between them. I suffer no ill effects from the chain length when using the 11-28.

    I'm doing something very similar except I picked up a Force RD to go with my 12-28. haven't got it on the bike just yet, but will soon.

    I went the other way for my needs, and had to swap parts out. You can adjust into a smaller <32 cassette, but you can't adjust from non-wifli into >28, you have swap parts. It was an adventure, and the principles all work to help you out.
    -cassette-install what you like, matching brand probably a good idea.
    -chain, between a 32 and 28, one link to long, but not significant, derailleur can handle it, or just remove a link - ez. If you have some fair mileage, wouldn't be a bad time to put a fresh chain on.
    -derailleur- the difference between wifli and standard are as I remember a 5mm longer body, (not just the cage is longer), the distance between the pivots is increased to clear the larger cogs. It has been argued whether a short is 'crisper' than wifli, I couldn't feel it, but to some folks, they have that ability, I don't.
    -adjustments - in these days of mass production, it should be cool, maybe a tweak. Don't forget to check/reset the b-screw for clearance.
    In my adventure I built the bike, ran a few hundred miles and figured I needed MORE gear, had to flesh all this out found you can't just swap cassettes and I ended up with the RD, cassette, and chain leftover-sitting on my bike bench.
    I hope that this helps.

    Yes this makes sense. The Wifli seems like the equivalent of a long cage RD. Good to know that I can just swap them out on demand if I ever go somewhere with more climbing. wiggle has a really good deal on the SRAM PG1070 that I'm probably going to jump on.

    that 11-32t cassette is a strange thing. I always feel like I shifting trying to find that sweet spot, cruising speed gear and its just never there. I feel like I'm either spinning out or mashing too hard. Hopefully a new cassette will alleviate this problem

    In an 11-28/11-32:
    11-12-13-14-15-17-19-22-25-28, 11-12-13-15-17-19-22-25-28-32
    So you get the 14 you didn't have in the 11-32.
    11-12-13-14-15-17-19-21-23-26 seems like it would be pretty smooth if you could run it.
    Sometimes I feel I didn't have the 'right' gear with that spacing, but I need both ends here in CO.
    Strange to talk about when my first bike had a 14-17-21-24-28. In retrospect, I am spoiled.

    Absolutely no need to shorten the chain.

    if the OP doesn't change the rear derailleur, why would he need to shorten the chain? please explain...
    I work for some bike racers
    I've got some bikes, some guns,
    and a bunch of skateboards
