It works a treat. You get two upper clamps so you can run 7x9mm carbon rails or 7mm round alloy rails. The lower clamp can be reversed depending on your desired saddle angle in relation to your frame’s geometry. Once the saddle rails have been inserted in between these two clamps it's just a case of tightening the titanium bolts with a 4mm allen key. Micro adjustments are possible once the saddle is pretty much in place: tightening the front bolt will lower the saddle, while tightening the rear will raise it.
Aero road bikes come with aero seatposts. These are flatter and designed to channel air more seamlessly, limiting the resistance that slows you down. Rear lights can be a bit of an issue when it comes to an aero post, although many brands now offer adaptors that allow for the shape. But bikes and bike parts are more than just functional items. We’re drawn to bicycles and components that not only appear to fit our performance criteria but also our eye. Enve makes lovely looking parts, including this seatpost, that no doubt provide joy to those who shell out their hard-earned cash for them. And in the end, it’s hard to argue against that. Specs Cane Creek’s eeSilk suspension seatpost offers 20mm of elastomer-based vertical compliance and is made from forged and machined aluminum with titanium fastening hardware. This emphasis on premium materials, along with the post’s minimalistic design, means the eeSilk weighs in at less than 300 grams–a comparable weight to many performance alloy seatposts. The FSA SL-K head is harder to adjust precisely and it's heavy. FSA K-Force is lighter and has a similar 2 bolt design to the Save and exists in 25.4 but may be harder to find.

One thing I really liked about the Kinekt is the saddle rail clamp. It has two simple screws to tighten and adjust the saddle. There’s a spring that keeps tension to separate the lower and upper plate. This self-fixes the nuts into place so you don’t have to hold them while loosening or tightening the plate into place. A nice touch. When it comes to cancelling vibrations, there are several steps brands take to aid this in frame construction: using thin seatstays; placing the seatpost clamp lower down so that more seatpost is exposed (allowing for more flex); and using a narrower seatpost A carbon seatpost is effectively an additional step; a cherry on top.
On my scales it weighs 202 grams. Light but not exceptionally so. At this price point seatpost you might expect it to be lightest in class. But Enve has built its reputation on more than just making objects for those preoccupied with reducing the weight of their bikes. Take this seatpost’s clamp design, for example.Having said that: going a bit too narrow can be fixed with some DIY shims from Coca-Cola cans (that’s one thing that drink is good for 🙂 ), When engaged, the suspension linkage compresses a steel spring inside the post’s column that’s sandwiched in between two plastic spacers. All of these innards are compressed against a hollow plastic pipe that seats against a threaded preload screw at the bottom of the post. Redshift also includes a smaller, secondary internal spring to provide additional firmness, depending on your desired ride feel. The photo sequence above shows me sitting on it set up out of the box—main spring only, with preload somewhere in the middle—with its sag affected by only my weight (about 175lbs). Seatposts by nature are simple beasts. Dropper posts notwithstanding, the clamp is the only mechanism. Most posts have adopted versions of the same system for years, with a variation in the number of bolts often the only difference.
All that said, I personally prefer the two elastomer-based suspension posts I’ve tried. Similar to a well-tuned suspension fork, the elastomer posts seem to settle into their travel instead of being squishy and active all the time. As such, they provide more support off the top, and only become active when pushed (or when bumped). I spent a lot of time on the eeSilk, which is the most minimal, of course, and provides the least amount of cushion. But I also liked the new 4th gen Thudbuster and will be curious to see how the elastomer holds up over time. Seatpost diameters are usually a multiple of 0.2 mm (but not always, as tables 1 and 2 show). If a measured value differs and most closely matches a value that is not a multiple of 0.2, there is a high probability that the closest multiple of 0.2 mm size will fit. For example, a measured 25.5 will most probably fit a 25.4 mm wide (nominal and measured width) seatpost. A rule of thumb is that the widest post that slides in without being forced (other than pushing or twisting by hand) is the right one. If it drops in, with play, before the pinch bolt is tightened, the seatpost is probably too narrow.
Suspension Seatposts Wrap Up
Though some brands like to play exception to the rule, the majority of bikes are designed to fit a seatpost of either 31.6mm or 27.2mm. The first bicycle frames were made mostly from steel, with steel tubes of a standard (outer) diameter. The British and Italian standard diameter for seat tubes was 1 1/8″ (28.6 mm). Older French bicycles used 28 mm tubing. Old US bicycles (mostly BMX and older bikes that used one-piece cranks) was 1″ (25.4 mm).
