I ride clinchers, but chose the Tubi over the Dual because I use a crank Bros Speed Lever as my tire iron. The extra length helps allows the speed lever to fit inside. I'm kind of a bag-nut and have a milk crate in my garage full of bags I tried and didn't like. The Arundel solved that. The bag is extremely well-made, everything fits that I need for a ride with room to spare. What more does a guy need! Great product! I never go on a road ride without it.
