Hi, I have a Birdy monocoque Graphite which was bought around 2006? I one time I changed a few things, including carbon Joseph Kuosac wheels and made the bike 10 speed. However, I was thinking of going back to some steel rims as I find that the carbon wheels dont stop me as well now that I have put on more weight. Where could I buy some wheels? Hubsmith? I am in Australia. Also I wanted to change my brakes but the good rim brakes are harder to find - has anyone used the Paul V Brakes? They are expensive but I do need to be able to stop. (the other option would be to sell this birdy and buy one with discs).
