Hey people, I aint posted on here in ages. Anyway im in need of a new stem because I have a onza one that will only fit onza bar (due to the middle size onza have made 28mm). What stem would be best??? 1. Try-all 31.8mm Clamp http://www.tartybikes.co.uk/product.php?id=328 2. Echo Hifi http://www.tartybikes.co.uk/product.php?id=327 P.s. the stem is for the echo tough bars. ~Matty
