    Need Advice on my next Fixed Gear Rig! Carbon ? Aluminum?...Looking for lightweight!

    Hey Guys,

    This is my first post, so be kind.

    I have been road biking for about 5 years, commuting by fixie for about 2.

    My current fixie is heavy steel, which is okay, except I'm tired of lugging it upstairs and hanging it on the ceiling at it's current ~30lb weight. And of course if I am going to upgrade, I'm going to go over the top. It's who I am.

    So....... I want to start by finding a carbon frame. I'm having a hard time finding a carbon frame with track "dropouts". I know I could just find a road bike with vertical drops and find a magic ratio or use an eccentric ENO hub, but I'm a purist. Although, that option is still open. I just need advice. My current road bike (aluminum) is about 18lbs when race-ready. Since my next fixie won't need nearly as man components, I'd like to get it below that weight; however, anything below 20 is fine.

    Thanks for the help!
    -Nick

    There are guys in this forum with steel bikes less than 18 lbs. Just saying. I'm probably not the best to help you in your search for a carbon frame but they do exist. Be prepared to spend lots.

    Carbon commuter fixed gears don't exist, because there isn't really a market for them. But there is lots of lightweight steel and aluminum around. The All City Thunderdome is lightest bike in my head right now. That is not scientific, but they are damn light.

    18lb steel bike? Whoa. I'd be happy with aluminum. Thanks for the immediate responses guys! I know a carbon fixie commuter with track geometry sounds wacko. But I'm a wacko. So it's okay.

    Sounds like you are looking for a leader though.

    If you insist on carbon, Appleman will build it for you. It won't be cheap, though.

    Planet-x and Dolan both have carbon frames. But there is a reason that track bikes tend to be aluminum and carbon will definitely increase the dooshiness factor. Trust me, aluminum is already tarck enough.

    My all steel Soma Rush weighs under 18 lbs, and it is a great commute bike.

    Pretty much any of the mid level or above aluminum track frame can be built to be under 20 lbs (or well under). Leaders, Unknowns, Superbe Sprints, Cinelli Mash, Bianchi Pistas. Lastly, you might want to put more thought into where and how you will be riding instead of how light it is to carry up stairs.

    I appreciate everyone's input. I never even knew some of these bike brands existed.
    @prooftheory: I don't care about "doochiness factor". If people hate, let 'em hate. I realize that what I'm doing is just about the opposite of practical. I also usually keep my bike inside in my "office" (closet) after the commute so no worry of theft. (Also, I don't know what "tarck" means. I know you typed it purposefully, since I've seen it other places. )

    I just want a bike that is as light as it looks. I have looked into all the bikes you've mentioned, and there are a lot of light alum. and steel track bikes that I'm interested in. I got sidetracked however when I noticed that some TT bikes (or tri bikes; I can never tell the difference) have horizontal dropouts. Am I getting something wrong? Or is possible there is some TT/tri bike with horiz. dropouts that I could set up as a fixed gear?

    I'm continuing to sort through all the bikes you guys have recommended. But I also have noticed that Bike Nashbar has a $600 carbon road frame/fork, which is quite a steal (although I don't know how much it weighs, and, just like steel, not all carbon is the same. I'll check into it.). Has anyone has experience using an eccentric hub on a vertical dropout to tension a fixed gear's chain? Any problems? Or can anyone tell me any future problems I could run into by using a road bike with vert. dropouts as a fixie?

    Thanks again for everyone's input. I really appreciate your time! (Sorry I have so many questions.)

    My janky Scattante SSR was a little under 19 lbs in brakeless tarck mode, could've been lighter if not for deep v's. If you insist on steel, Wabi seems to be the most bang for the buck. One of the mods (@AngryScientist i think?) has one of the nicest Wabi builds on the entire internets:

    There are lots of tri bikes with rear facing dropouts. There are two problems with them as a commuter. The first is somewhat minor. They tend to have short dropouts which mean they aren't as adjustable for different cogs. The second problem is they they have a geometry for people layed out on tt bars. They generally have an extremely upright seat stay and a somewhat lax fork rake. If you are steering from your elbows this might be okay but for anyone else it produces a really wonky ride.

    Tarck just means "track-like for the purpose of street-cred but not really track".

    Oh... Tarck. Hah. Well I don't care much about cred. Unless that cred makes my girlfriend like me more. Although she'd rather me spend the money on her, I'm sure. My primary goal it to have a super light fixed gear bike. For fun/because I can. Not for any other reason. If you can recommend something other than a track frame and light components to aid in my pursuit of a "super light fixed gear bike", please tell me!

    I forgot that TT/tri bikes are ultra aggressive stance, I'll probably stay away from them since I already like to keep my seat pretty high on my roadie.

    I'm seriously wading through all the new options I have now. Wabi is looking very promising, although I must say the idea of a custom Appleman bike sounds tempting.

    Again thanks for the input!

    If you have that kinda dough just sitting around look at Icarus and Geekhouse. They both will have wait list for custom frames though.

    If you really want the lightest bike possible you should be looking at something like a Ti litespeed with an eno hub and really light wheels. For advice on this stuff you should look around the weight weenie forums. At the end of the day though you will have just spent a lot of money on something that isn't really that much of an advantage. You would be better of just losing an extra few pounds of gut. Just get a nice frame and light wheels and you should get under 20 lbs easy. If you want to spend a lot of money "because you can" then just send me a check .

    If you get any newer carbon road bike that uses a bb30 or pf30 bottom bracket it's easy to fit an eccentric bb in there. Just did it myself yesterday. Easy enough to adjust tension although obviously not as easy as horizontal drops.

    My 722 in singlespeed mode is ~17.5lbs with a carbon fork, most of the "lightweightness" is in the wheels though.

    building a SS

    Hi all.

    have been lurking awhile and finally signed up. Found some stuff I carried back from china for a project which never got started.

    Embarking on my first self build project and probably the simplest would be to do a single speed. I have the 2 in my store and wonder if I can use them to build something under 15lbs.

    here is roughly what I got though not the exact same model. can anyone help with the parts list i need? most likely a flatbar.

    Ahhhhh!! You people are giving me sooo many options.

    Again, I realize it's not much advantage and lots o' dough. If I want an "advantage", I'll upgrade my racing bike (the one with gears).

    I'll look into Litespeed and Icarus next.

    Thanks!
