Carbon C-thru bike frame

Martin wrote in to point us toward this amazing carbon fiber bike frame from Brano Meres –

During construction, all the beams were bonded together in the frame jig, with systematic and precise control of the position and alignment in the structure and the overall geometry of the frame. Once all carbon beams were bonded together with special epoxy resin, I lashed each joint with carbon fibers to ensure their strength. This was almost surgical work, really requiring a lot of patience. The critical parts of this frame were the connections of the “main tubes”, mainly head tube and BB area, so I paid a lot of attention to these areas. Then, each joint was softly sanded to have a smooth shape. On the frame, there are more than 300 joints, this painstaking work took about 300 hours of my life…

    The “C-Thru” was just a play project for Brano, but he also plans to sell a bamboo frame starting this summer.

    For more geeky fun, Brano also is experimenting with a bamboo composite, which is bamboo fibers in a polymer matrix, exactly like carbon fiber except it’s made with bamboo fibers. His bamboo composite frame looks and feels just like a carbon fiber frame, except it’s very very flexible.

    That Looks incredibly sexy… However I wouldn’t trust it on my daily commute. I have a scary vision of a frame crack induced pavement face plant. I’ll stick to solid Carbon Fiber for now!

    wow, that thing would have the woooorrrrssst aerodynamics ever. too bad its the coolest looking thing ever.

  4. sl says:

    all you need to do to make it aerodynamic, while keeping the light weight, is put something like shrink-wrap or a thin mylar film over it.

    Did this or the Arantix ( come first?

  5. bob says:

    surely the whole point of making such a bike is its weight?… which is?

  6. bob says:

    bob you idiot

    The weight of the frame is 1215 g (2.7 lbs).
