Hey all,

I've added a 30 degree stem to put me more upright, but now my feet want to be more forward than the current location of the bottom bracket. So now instead of swapping my handlebars from drop bars to flat, to compete my road-to-commuter conversion...im looking for a carbon commuting frame like the Specialized Sirrus, Cannondale Quick, or Trek FX (i can't find the carbon framesets sold separately). Carbon is excess, but i'm getting old so i'm going to treat myself.

I was going to use a chinese carbon endurance frame but i think i will have the same problem where the bottom bracket is a bit too far back for an upright seating position.

has anyone come across any carbon commuting frames that they can share? thanks!

Ebay has lots of frames . maybe nasbar they sell kestrel bikes , they make a flatty..

What benefit would a carbon fiber frame bring to a commuter bike?

Calfee, Parlee, Holland and lots of others will build you any carbon frame you want. No problem. Treat yourself to something that will pay back with every ride.

Top of the Trek FX line Bikes, have a carbon frame and fork.
buy the whole bike and then change a few components perhaps?

I'm not sure if any of you have ever been "pen addicts," resulting from schooling or a career involving lots of sketching and writing. But I have, and found that each type of pen, from ballpoint to gel to liquid, each with their tip size and ink consistency, not to mention barrel/total unit weight, material feel, and grip feel went from becoming trivial to very important. Such that i would seek out to try new pens because of certain features, materials, or weight balance etc. I would pay $10 to try out a new pen even though I have a sub $1 pen that works fine (Papermate Inkjoy, retractable, blue, 1.0mm), and its sort of the same with bikes.

Wait, you write with your bikes?

That is why he needs a graphite frame....

I'm a bit confused as like the Sirrus does come in an all carbon model.

If you want a different riding position to the point of noteably reduced efficiency, but more upright, those bikes stop caring about efficiency, so they start using fatter tires and don't really go into full carbon.

Haven't seen any carbon bikes as you describe.

If you want something like an Electra Townie but for longer distance, RANS makes their crank-forward bikes.
They work best if you lean forward somewhat--but because of their geometry and seat, you can adjust them to allow sitting upright if you want.
They do significantly improve comfort in several respects over a normal frame (less butt, hand and neck pain) but they suffer from having a limited ability to pedal out of the saddle and limited rack options.
And no carbon... They used to be steel but are all aluminum now I think.
The Zenetic is the premium road model. hXXp://shop.ransbikes.com/product-p/babk0018.htm

No other company makes anything even close to this frame geometry. And all the other ones still use a normal saddle, which is the cause of butt pain.
I've had a Fusion for 12 years. I would only replace it with another similar RANS model.

I'm sorry.

Even some carbon frame models 10 years ago are very light. It would have to be a road bike and converted into a "commuting upright". You may even get it close to 15 pounds or just around 16 pounds. But no fenders, or anything attached, please!
