Fixie Inc ( Cycles for Heroes )

I saw that in the Bike Show a while ago, it does look impressive, especially with hydraulic brake (they used a 'convertor' to make it work with drop brake, bit of an unnecessary weight IMHO).

Very clever.

I'd rather just go striaght mechanical though. Simplicity FTW.

I keep expecting Hydrolic sti levers to crop up. They wont be cheap though. Niche product, and all that.
