    Ultralight TCU

    Metolius designed its Ultralight TCU to give you tiny but bomber trad gear that doesn't weigh you down. Its lightweight appeal is due to the Direct Axle Technology, which places each lobe as close to one another as possible. This technology also helps you set each cam in tricky, shallow, and narrow placements with ease. Metolius made each TCU with three wide lobes that increases its grip on the rock as opposed to conventional TCUs or even four-lobed designs, and each lobe has a cam stop that helps it act passively like a stopper. CNC machined means each cam gives better precision so you don't fumble around when you're placing it. The U-shaped double stem is very durable, and yet remains highly flexible for better control when you're placing it or your second is cleaning it. Each cam comes with a color-coded Monster sling for easier identification on the wall, and the Range Finder on sizes 2 - 4 let you know if you're placement is at the most minimum or maximum range available on the cam.  

    • The lightest triple camming units from Metolius for trad climbing
    • Direct Axle Technology allows for trickier placements
    • Range Finder helps you find the correctly sized placement
    • Item #MET000C

    Love Tiny Pro

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

    Love the size and the look. Sort of old school and perfect for boosting confidence around the corner of The Unsaid in Eldo. Excited to see where I place this thing in the furture. Thank you Backcountry and Metolius. You guys Rock!

    Love 'em for funk and finger sizes

    • Familiarity: I've put it through the wringer

    Replacing a blue TCU that got lost. Pretty much my favorite TCU ever, it loves pin scars . It's saved my ankles a number of times. These fit places .3-.5 C4's and other wide head cams just won't fit. The size ranges complement X4 sizing as they usually provide a slight offset in the similar sized BD cam. If you climb on granite other other rock with funky placements these things are awesome!

    That said I don't carry about a #3 (orange). But, in the fingers to micro sizes they are great.

    When nothing else fits

      I always seem to find a place that the ultralight TCU fits when nothing else will. I dont carry a whole rack of them but for smaller placements these can't be beat. The blue, yellow and orange are my go to pieces for fingers and other small pockets. They just always seem to fit.


      • Familiarity: I've used it several times

      I've yet to take a fall on one, but when the going gets thin, I really appreciate these guys. I'm not a fan of the TCU design in larger sizes, but the 00-1 are light, easy to use, and inspire confidence in thin, shallow cracks that would otherwise have me a bit freaked.

      Every climber should own a few

      • Familiarity: I've put it through the wringer

      I didn't know much about these tcu's until I climbed on a friends and then decided to pick one up and try it myself. I haven't gone on a climb since without them. These are a great alternative to master cams or x4's because they place in short but wide pockets (if that's possible). #1-#4 are the most useful IMO. Haven't used 00 or 0. If I could only choose one it would be the yellow #2. If you already have a set of small cams, make these your second.

      I've mainly used them in the North Cascades and Little Cottonwood Canyon. And yes, they're very lightweight.

      What is the difference between the Ultralight TCU and the Ultralight Power Cam? I see the red in both categories and can’t find out the differences.

      The biggest difference between the TCU's and the Power Cam's is the number of lobes each cam has. The TCU has three separate lobes (TCU stands for Triple Cam Unit), while the Power cam uses four separate lobes. Having only three lobes on the TCU gives it a narrower head width, making it more ideal for narrow placement such as in pin scars or small pockets (there are much better options out there though!); while the four lobes on the Power Cam give it more versatility in cracks with uneven surfaces, as well as more surface area to bite into the rock.
