So I made one of the classic blunders and bought a large (320mm - for 28") Pletscher double kickstand instead of a small (290mm - for 26"). Should I try to return it (hassle) or install it and cut it down? I'm running 26"x2.15" tires. I'm guessing cutting it down shouldn't be a problem unless the two different models have differing amounts of sideways splay.
