    Shimano’s sender specials.

    Shimano’s Zee Crankset is designed for the downhiller on a budget (um, that’d be all of us, Shimano). At any rate, the thick-walled aluminum arms and steel axle are built to take a beating season after season. They come equipped with a single 36-tooth chainring, and are compatible with 10-speed drivetrains. It does not include a bottom bracket, and it’s available in everything from DH-friendly 165mm arm lengths to a more-conventional 175.

    • Thick-walled aluminum crank arms
    • Steel spindle
    • 104 BCD
    • Bottom bracket not included
    • Item #SHI002A

    Great value

    Familiarity:I've used it several times

    The product description says bottom bracket isn't included, but mine came with one. If you don't have the money to drop on a set of Saints this is a really good option. I have had a Hone crankset on another bike for over a decade and it hasn't failed me yet. This is basically the second generation Hone, Saint's little brother and it looks a bit more burly than my Hone. So far so good, hoping these last just as long. The steel pedal inserts are nice. These cranks are replacing an ancient set of Hussefelts that were stripped out at the aluminum pedal threads.

    Great Cranks, BB Included

    Like Dylan mentioned, there is a BB included with this set. The cranks are super solid and look great too in case you care. Great value Crankset.


    A little bit of profile.

    These are not wimpy cranks. These things are tough and you can tell that just from the profile.



    Look at that sweet, sweet crank. Nice lines and some beautiful color.


    That crankset tho.

    Here is one of the first rides that I took my bike on after putting on the cranks. Rainbow Rim Trail

    Doesn't get any tougher than this.

    Familiarity:I've put it through the wringer

    I wanted to get a crankset that would go along with the burly nature of the bike that I was building, and the Zee crankset is the perfect addition. I built up a 2015 Surly Instigator 2.0 and wanted something that I knew would last. I already had the Zee derailleur so decided I would try the matching cranks and I'm glad I did! I'm not a big downhill rider, but being a bigger guy I wanted something that I knew would be sturdy and be able to withstand the style of riding that I do. I think the color looks great, they have a very solid feel to them, and going with the 175 length they feel just like my other cranks that I had on my other bike. The only reason that I didn't give these cranks 5 stars is because they are HEAVY. I mean, they are downhill cranks, so they are meant to be built tough, but if I was trying to build a light bike, these would not be the cranks I would use. Where I really am not crazy concerned about the weight, it wasn't a huge issue, but for some people it could be. Built solid like Shimano always does, and for the price you can get in to some awesome cranks! Check 'em out!

    Just picked up BB included

    Familiarity:I've used it once or twice and have initial impressions

    Just got this crank set and a Bottom Bracket was infact included Shimano part # SM BB51. More indepth review to come

    really? that makes it so much more worth it i need one badly!

    Unless the package I received was a mistake, I definitely received the above BB with it.


    Can I use this on my Trek that has a press fitted BB?
