Got your own totally sick lightweight build? Use the “Submit Tips” link above and send over a complete build list, photos and a pic of it hanging from the scale that clearly shows the actual, complete bike weight. We’ll feature the best ones here. In the meantime, here are a few others to make you drool:


  1. Nice & mean-looking ultralight…

    What I’d like to know is the brand & model of the tires, since they aren’t listed in the specs and in the pic the logo is so stylized as to be illegible!

  2. Just about any local bike shop in the US will be able to order the acros system in a couple of weeks. Two of the largest distributors are carrying them.

  3. All that money into a bike only to limit how much you can ride it? I guess this calls for one of those “$xxxx for blah blah…. blah blah, priceless” sayings?

  4. That thing is cool but definitely not for my 330+ lbs Super-Clyde self! I would be picking carbon fiber chunks out of my ass for a month when it exploded under me after a few pedal strokes!

  5. That is a really nice “bicycle shaped object”. Lets weight it again after about a 100 hours of riding and see what it weighs.

  6. People, it’s a race bike. I doubt it gets 100 hours in a season.
    I have a sub 19 lb race bike, solely used for race day.
    He probably has other (heavier, more durable) bikes for training.

  7. Hmmm maybe not even pros… perhaps just the top finishing hardtails of recent and/or major XC races (seems apparent this bike is spec’d specifically for XC races, yeah?).

  8. This is the most ridiculous cable routing I’ve ever seen. Talk about dropping the ball (on the manufacturer’s part). If it’s a fully hydraulic system then there should be 90 degree elbows to eliminate that hideous mess. Take a look at the pics on the blog. It’s horrific!

  9. I also drive bikes under 17lb and i drive them each more than 10 000km a year !! the light bikes israel bike is also nice but Scrub rotos don#t work so good as steel ones !!!

  10. Mike, your an idiot. Carbon fiber has MORE than proved itself in mountain biking. Ask the Santa Cruz DOWNHILL team about their carbon fiber frames, hell, their carbon fiber wheels!

    It’s a sick bike, I probably wouldn’t race it, but it’d be fun as hell to ride! Also, the reason the cable routing looks bad is because the bike is designed to have internal cables (with standard cables, obviously), and I’m assuming the hydraulic hoses couldn’t be internally routed.

  11. Colin, In all due respect, we’re on the same team, I won’t flame you but will respond with the fact that one crash on that bike and its off to the shop for replacement. Have you ever seen a carbon bike get side loaded? It never ends well.

What do you think?
