Review on LERWAY Bicycle Bike Stem Riser by Brent Dietrich

I wanted to lift the MTB handlebars because my palms hurt. This allowed me to raise them about 3 inches, which put me in a more upright position. Everything looks very solid. I like that the necessary Allen keys are included in the kit. Installation was easy (after watching a video on youtube). Be sure to check the length of the cables to ensure they are long enough to raise the handlebars. I bought a set of cables knowing some of them would be too short. I ended up replacing both derailleur cables to compensate for the extra height.
