Initial Reaction: Colossi Cycles’ Double Dog Stem Feb 7, 2011


When I first saw the Colossi Cycles Double Dog stem, I salivated, even though I was unsure of the structural stability of its design. Sure, I’ve seen similar stems before, but always with the slot at the top of the stem, never on the sides. A few days after I posted it up, I got an email from Colossi asking me if I’d like to try one out. Not knowing immediately what I’d use it for, I asked for a quill stem. Then a few days later, a new project came up so I specified a 110mm 1 /8″ threadless at 73°, the classic angle used by Cinelli for their 1a road stems*.

Check out more photos below!


Well, Saturday morning, it came in the mail! I was really stoked on it. Right out of the box, I noticed how solid it was. But something looked a bit off. The 73° was used as a rise (which technically makes it a 107°). Initially, I was a bit bummed but then I realized that it’d be perfect for another project.


So once this new frame comes in, I’ll toss it on and give a full review of it. If my gut instinct is right this time, I’d safely say that this sucker won’t flex as much as I thought it would initially. I’m holding it right now, alongside a Thomson and a Salsa and it’s pretty freaking solid. I can’t wait to ride it!

Thanks to the Colossi team for hooking it up! Check out a few more photos at my Flickr.

*Note: The Cinelli 1a measures 73°, the 2a has a sharper angle of 65°, 3a even more extreme, 58°. But in today’s terms, stems are measured in (-)degrees. So a more fitting note would have been -17°…

    17 degree is supposed to sit flat on a level top tube. this looks like it is upside down unless you plan on ride it in the “super boner” position. anyway interesting stem, I’m curious to see what you think about it.

    You mean 73° is supposed to sit flat along a top tube… ;-)

    I’m either going to use it on a city-road bike or a new track bike. I much prefer a positive rise stem for both applications, especially the track bike.
