    Best bang for the buck upgrade

    • Familiarity: I've put it through the wringer

    This wide-range cassette is perfect if you are looking for an inexpensive 1x11 upgrade. I have these on 2 of my bikes and I love the wide range for my single ring up front. If you are looking to upgrade your drivetrain to 1x11this is the best bang for the buck.

    11 Gear of Fun

      XT is the gold standard for Shimano MTN bike parts and this cassette fits perfectly into that standard. I bought this because my old one just had too many watts on it... over 3000 miles of dirt covered brutality in it. New chain and a new cassette = brand new bike feel!

      Good Casette

        Paired with mine shimano xt di2 derailleur, this cassette is buttery smooth throughout all gears with regular chain maintenance. I would say this cassette is a close second behind sram's eagle drive train.

        11-46? HUGE RANGE
        HG freehub? NO PROPRIETARY HUB!
        Classic stylings, great range, and reasonable pricing for a fantastic piece of componentry.

        Great Product - Perfectly priced!

        • Familiarity: I've put it through the wringer

        Decided to upgrade from a 10spd to 11spd. Thought about saving a few $ and going with the SLX cassette. But, based on the price difference, I figured might as well pay the little extra. Happy I did. a Buddy of mine purchased the SLX blend ripley and converted to the M8000 rear derailleur at the same time I went m8000 full rear (xtr shifter). There is a noticable difference in how smooth the shift quality is on my bike vs his now. He went so far as to ride my bike, feel the difference, then come back to comp cyclist and purchase the XT cassette.

        Shimano value and quality-thumbs up

        • Familiarity: I've put it through the wringer

        The shear volume of great reviews on the XT lineup speaks for itself. I'm running an XT 1x11 (46t) drivetrain and love it. Yes, there is a pretty large jump between the 37t and 46t granny gear but its nothing that's gonna ruin your ride. The 46t cassette I bought is the most cost effective drivetrain upgrade out there. You can retrofit your 10spd HG freehubed bike into an 11 spd 1x gear monster with just a shifter, cassette and chainring...that's all you need. Yes, there are prettier, shinier, more goldier cassette options out there, but for shear bang-for-the-buck upgrades, nothing beats the XT drivetrain. Good stuff to get your goods going.

        Good but cheap 1X11 solution

        • Familiarity: I've put it through the wringer

        This is great solution for anyone who wants a good but cheap 1X11 solution. Shimano cassette is made of great materials/construction, crisp, and effortless shifts. This cassette it does the job well, like shimano XT components typically do.

        The Workhorse Groupset

        • Familiarity: I've put it through the wringer

        I think that the XT groupset is one of the best you can buy at this point. They are fairly light, very reliable, and will last forever. Not to mention, it's super affordable! Easy to install and also really easy to maintain. Might not be the ultra light race set up you want, but is just flat out reliable.

        Best Cassette for my Bike

        • Familiarity: I've used it several times

        This was the best thing I could have done for my Surly Krampus. The stock 1 x 10 was tough to use for climbing. When I switched to 1 x 11 it helped tremendously for climbing and extended the amount of time I could spend on my bike. There is just barely enough clearance with my plus sized tires (29 x 3). The bike Gearheads really helped me in getting the right set up. Consulting them before buying may really save you a lot of time and frustration for your next set up.

        That's a big cog you got there.

        • Familiarity: I've put it through the wringer

        Who would have thought that one day the large cog would be bigger than your brake rotor. I was skeptical of 1x for a long time but riding it on a long bikepack in Baja made me a believer. The jumps between gears are a bit big in some cases but the shifting is smooth and the low end gearing is great for hauling a loaded bike up long mountain passes.

        Update. Still running strong with no shifting issues. Lots of miles on cogset.

        the gearing you've always wanted

        • Familiarity: I've put it through the wringer

        I bought my wife the 11-46 because she excels at downhill riding far more than the uphill stuff. Now she can climb anything. Compatibility questions? Hit me up at

        11-46 has big jump on the low end...

        • Familiarity: I've used it several times

        See my prior shimano just works. That said, the 11-46 leaves me a little puzzled. Bought it for a new bikepacking rig set up 1x--that is, a bike I'm going to lash a bunch of stuff too, up to 20lbs of water at a time and go ride singletrack for a few days on end... As such, I'll spend a fair amount of time twiddling between climbing gears and I find myself missing a 42ish gear... The 46 bailout is great. But the next step is 37. For regular mountaing biking or flatlanders wanting a bailout gear, this is probably great as it maintains a nice spread across all the other 10 gears. But for my intended use in the rocky mountain west, I could ditch the 11t in exchange for more choices for climbing.

        When will you have the 11-46 ready to ship? I'm ready!

        Hey Dusty! Looks like the estimated arrival time for first shipment of the 11-46 to get in is 8/09! If you or anyone else has any questions on it or would like any help placing an order feel free to reach out to me! Cheers, Connor

        If I currently have a rear hub running a 10 speed shimano cassette, will that hub be able to run this 11?

        Yes, shimano 11 speed cassette fits on the same free hub body as 10 speed. SRAM 11 speed needs a new free hub body. I am currently using the same hub for shimano 11 speed as my old 8, 9, & 10 speed cassettes. One of the benefits of the shimano design vs. SRAM.
