Hi everyone, I have a question, I ride a mountain bike, and I want to change from knobbies to slicks, I currently ride 26 x 1.95. What I was wondering was how low on size can I go, I was thinking 26x 1.4 - 1.7, can I go lower, and also do I have to get new rims to do this or can I do do it on the same rims? Has anyone tried Ritchey Tom Slicks, I saw a review for them on the internet, and they seem to be prety good.
