Review on Emoly Bike Stem Riser by Devin Girard

Does exactly what it's supposed to do, raises the handlebars to a height. Mounted with some lubricant on the threads, always a good idea for steel screws in aluminum threads. Tighten the bottom bolt first, as the design allows for a tighter clamp, and tighten both bolts evenly, a little at a time. Do not overtighten or the aluminum will break. Street tires, padded seat and this stem make my old school mountain bike fun to ride again :)
