KS (Kind Shock) Supernatural Seatpost w/ remote 31.6

Initial Impression

First thing you notice right out of the box is the high production value; easily on par with other industrial design stars of the cycling world.  The anodized red details are a nice contrast to the black and tan of the main tubes—making for a sleek, attractive package.  The Supernatural post has 150mm of infinitely adjustable travel around 1” more than its competitors.  The remote is nicely machined with no rough edges and the cable and braided housing appear to be of high quality. Even though the cable is disconnected for packaging, the ferrule and stop are pre-adjusted and simply require the tightening of a 1.5mm set screw for installation.  KS has included an in-line barrel adjuster for fine tuning and I assume it will have adequate adjustment to tune out any initial cable stretch.  I wish they had included a longer cable though; I didn’t have any routing options because the stock cable is too short to reach around the headtube to the cable tabs on a large Intense Tracer. One well thought out detail: the remote assembly replaces a lock on clamp on an ODI lock-on compatible grip. The two bolt head is well made and provides a secure connection with the seat rails.


On the trail

I installed the lever on the left grip just above the front shifter.  The assembly can be adjusted to the desired angle by simply loosening the lock-on clamps and rotating the grip.  The lever is convenient and easy to activate, although it is easy to accidentally grab for the seatpost control when upshifting (and vice versa)—I assume this will become a non-issue with practice.  Lever action is smooth and requires just enough force for a positive feel. The seat immediately responds, sliding upward quickly (but not with testicle damaging speed) and smoothly downward to the desired height.

Versus Gravity Dropper Classic

My previous seatpost was a Gravity Dropper Classic. The visual contrast between the units shows that Gravity Dropper has fallen behind the times with their design.  The Kind Shock unit seems much beefier thanks to the 31.6 lower diameter (the GD required shims from 27.2 to other diameters) and larger slider.  Despite the larger diameter, claimed weight is comparable, (GD 510gm, KS 525gm) and when you take into account the required shim, the KS is lighter.  The KS post has little or no slop in the post/slider interface while the Dropper moved slightly with every seated pedal stroke.  The GD has a front/rear two-bolt adjuster (think Thomson) however, which I prefer to the Kind Shock’s left and right attachment.  My Dropper was limited to three positions, for a total of a 4”adjustment range, which I always assumed was enough—until now.  Being able to fine tune seat height throughout an almost 6” range has proven itself to be indispensible on the rolling, technical terrain found in the Reno/Tahoe area.  – Sean
