I have a '06 Novara Randonee with Mavic 319 rims and Vittoria Randonneur 700x32 tires. These rims will accept up to 47mm tires (per http://www.speedgoat.com/product.asp...260&brand=155), but my Planet Bike fenders will only hold up to a 35mm.
My touring partner (BF) is riding a mtn bike with knobbies. I want to be able to keep up on the roads that he may be able to travel (within reason) and need advice on tires. I want tires that will handle fire roads and pavement. Is there such a beast? http://www.bicycletouring101.com recommends the Schwalbe Marathon Plus tires. Would these work for me? What width do you recommend?
