Honorable mention goes to the Specialized Future Shock, a suspension steerer. This cropped up first in 2018 Roubaix models and has since appeared on the Diverge gravel bike, Sirrus hybrid, and Turbo Vado SL and Turbo Creo e-bikes, all models that have a pretty high odds of getting used for commuting. I can't tell if it will last in the market but it seems pretty successful right now. Their launch marketing had a lot of head scratching assertions why they did it this way, while it seems pretty obvious - they wanted it to be small. But the thing surely works. Funny enough, the first generation didn't have damping and came with a few sentences of ad copy how it didn't need it... and the second generation got damping. It's only on Specialized, only a few years old, and I don't know where it will go from here. It could proliferate or die. But for today, it's an option. It only has 20mm of travel in its current form, but that's about doubling what you get from the tires on those bikes. Tuning is very limited. Past suspension products have always gotten longer but the stack limits the size. It's sort of reminiscent of the Cannondale HeadShok, though that was on the fork side and not the stem side. Like that, it's in the steerer and it's proprietary.




There is also a suspension stem available right now, Redshift Shock Stop, using... elastomers! Remember those from the first post? It has a single hinge instead of a parallel linkage like the old Girvin Flex Stem, so the bar rotates away from you when it moves.
