I’m pretty sure I know who this stem is for, but I won’t speculate or let it slip up prematurely. Horse Cycles is in the process of developing an old-school stayer stem for a bike company and here’s the first prototype. I’m digging this project so far and anxiously awaiting the final production models.
One thing I’ll say is I liked the option of being able to slide the clamp off the extension on the older stems. It allowed you to run the bars above the extension if you wanted to. Adding a “lawyer’s tab” to the stem prohibits this doesn’t it? Maybe it’ll change? Who knows. We’ll just have to wait won’t we?
