Octagon threadless stem riser. New, $50.00/each

Part# 31340

Here's the maker's explanation: Octagon is the first ever handlebar height adjuster that combines a simple, tool-free adjustment system with up to 3.5 inches of adjustable length, all the while assuring handlebar trueness. Octagon offers all the benefits of an angle adjust stem without shortening reach when raised. This unique design allows for handlebar height to be changed while preserving the way the bike handles and rides. The octagonal shape of the post also keeps the steering engaged while raising or lowering the stem.
