Here are two picture links for my new Conti GP3000 tires on my Pinarello, I still need to get a few things done on it#1 I have to redish the wheel and # 2 make it fixed ,Vetern-youth is going to show me how to do that, right now it is 42x18 and I find it really easy and the big ring is 53 so maybe I could use the 53 ring and change up the rear cog ,any idea's on what size of the rear cog I should use ?.... http://photos1.blogger.com/blogger/7...1/1600/a33.jpg http://photos1.blogger.com/blogger/7...1/1600/a11.jpg
