Ive been riding the ice proto for a while now and really like it, everyone who has had a ride on it says its the biz to. As Joe said its really nice on the back wheel and goes up to front wheel really well because its quite long. both frames come with the 350mm rear end which pesonally I prefur. It makes the back end flick through abit quicker, great for gaps and bunny hops!! The limey frame took me by surprise really as its a short frame ( I dont get on with short frames!! ) but this is quite possibly the best bike Ive ridden!! and before you all say it, Im not getting told to say it. Ill always give a honest oppinion of the stuff I ride ( ask Joe lol ) It rides reall well on two wheels, moves easy and feels really responsive. Partly because how ballanced the bike is and the weights good too. Ill add some more when Ive ridden it a little more (without scratching it giggle.gif sorry Joe )lol.probably be on the Notts ride this Sunday If anyone wants to have a sneeky peak. Ryan
