Hi all. After several reviews of previous Zonda posts I know these are the ones I want to upgrade my Alexrim 24's for. I know of a few online retailers, Wiggle, CRC and Ribble, does anyone know the best / cheapest place to get them from currently? Also, for the odd sportive and weekend use, what are the best tyres to use? I have some unused gatorskin 23s but not sure if they are a bit too "allround" to make best use of the new wheels - are GP4000 better?
thanks all!
