I found this kind of interesting.
"Graphite, the material used in pencils and tennis rackets, is many layers of graphene combined together. Isolating a single layer of graphite (graphene) was first achieved in 2004 at the University of Manchester by Andre Geim and Kostya Novoselov. The two scientists isolated the one-atom thick layer using 3M Scotch tape on a block of graphite... until Geim and Novoselov, work that subsequently saw the pair be awarded the 2010 Nobel Prize in Physics."
Kind of sully's the prestige of the Nobel prize when you can win it by sticking scotch tape to a pencil lead. Maybe in 2010 physics were just F-cked up and they had to pick these bozos.

Not only that. Andre Geim also happens to be the only person who got both the Nobel AND the Ig Nobel price... the latter for levetating frogs.
if they got rid of the big block of alloy they'd save some weight right there..

The article said this graphene costs 50 Pounds per gram. 50x7.5x1.31 (USD/GBP conversion) = $491.25 worth of graphene in the frame. They are taking orders for 3,995 Pounds per frame. 3995x1.31=$5233.45.
1% graphene. If the same frame has 0%, how would the two frames compare? Guessing it's all just marketing and experimentation at the moment.
Interesting that graphene is transparent though, who knew. Can a high % graphene frame be transparent I wonder, or even somewhat transparent..

Actually, it's not transparent at all. Considering that it's per definition a single layer of atoms(!) the 2% absorbtion it shows in the visible spectrum per layer is quite a lot.

Just saw the new GCN episode on this. Looks like the 350g milestone hasn't been achieved yet, still at 700+g. Wonder what's holding them back?

Why spend all that time, money and effort on getting this material applied to a bike frame, then make something that looks like what you get when you type 'road frame' into Alibaba.
