I have finally been paid for the damage and injuries I suffered in Nov 2013 and so I can finally replace the bike that was damaged.
I have decided to get another fixed and quite fancy disc brakes, the choice seems to be a Cotic Escapade which has front and rear discs or a Pompino with a disc fork and cantilever rear brakes.
I think the Pomp will be the best choice, I live on the edge of the Mendips and so have to brake quite a lot on descents, the front disc can take care of most if this. I also think it will be easier get replacement rear fixed wheels, I can't seem to see any that have disc hubs. I know that disc hubs are available but I am not a wheel builder and so I need to be able to buy complete wheels.
Any alternative suggestions or comments on the above would be welcome.
