    Lightest SS frame?

    What are some of the lightest singlespeed specific frames available? I'm considering building my next bike with a focus of being light. My current frame is a Niner One 9 RDO which is supposed to weigh 1235g. Are there any significantly lighter than this?

    Thanks!

    I don't know if you're gonna find much lighter than a carbon SS frame. Niner's are damn light.

    IMO, a hundred grams, or even two hundred is gonna pale in comparison to anything you do with building light wheels, fork, seat post/saddle and cranks. Those are (in my experience) where you get the most bang for your buck.

    Agreed, I would rather have a slightly heavier and hopefully more durable frame. Then really focus on the components for weight savings.

    My '01 Schwinn Homegrown frame is aluminum and weighs 2.9 lbs (~1320 grams). Not SS specific, so no horiz. dropouts and tug bolts/nuts. But sets up very nicely as an SS and weighs in at 19 lbs without breaking the bank on components.

    While the other posts in this thread are somewhat helpful, I thank you for actually answering my question I've been looking for lighter SS frames, and was wondering if I was overlooking something.

    I've got a 2011 carbon s-works stumpumper ss that weighs 1200g. That's the lightest I've ever seen. The one 9 rdos were more like 1500g with their ebbs.

    Got a scale shot of it?

    My answer hinges on the fact that you used the word "significantly." Level of significance varies person to person but I personally don't think chasing weight savings on the frame when you already have one that light is practical.

    I plan to invest a lot in the wheels and other components. Just want to make sure I start with the best foundation possible. I really like my niner, but I'm working to replace it in order to get a little better high speed handling and lighter weight.

    For me, I would consider frame weight savings of 1/2 pound to be significant. I do not want to sacrifice much rideability though. I have around 1,600 miles on my niner so far, and have hit plenty of jumps and rock gardens at speed. So far I've have 0 issues.

    significant on the scale, insignificant on the trail.

    If your looking at the whole package a carbon cannondale with lefty is lighter than a carbon frame and regular fork. Then again, just go with a carbon fork and your lighter with your frame that you got.

    The Open One needs a chain tensioner hanging off the derailleur hanger but the Focus Raven is 885g and then add a Beer Components or Niner or Wheels Mfg PF30 EBB and you're looking at a 975g SS frame. It's what I'm building next. I have built some light bicycles in the past. Search Mattkock on here. I built a 13.91lb. Niner Air 9 Carbon with a 1410g frame so this new build should be Freaking Light.

    Post a pic when it's done. If you want super light get a carbon gravel bike frame and build it up without the drop bars and mtn brakes. That'll be light.
