My new mountain bike handle bars were to far to stretch changing this stem raised the bars and moved them closer for a very comfortable ride

If you are looking for a more comfortable bike ride the Fifty Fifty extension is how to get it. The difference in riding comfort is AMAZING !!Next to converting from Mechanical Disc brakes to Hydraulic Disc brakes, and changing to a Zaccro Wide Seat, this is the BEST thing I have ever done to make my eBike my favorite exercise.The quality, fit & finish of the Fifty Fitty fork extension is EXCELLENT

Very tall and awkward to shift around. Worst part is I missed the short return window and am stuck with it. That alone is enough to pass on it.
