Installation was straight forward and even seemed easier than I remembered it? I saved the current seat angle, so I wouldn’t have to spend any time doing tuning, which can be a lot of work with that type of yoke system. You have to loosen one bolt and tighten on the other, back and forth until angle and saddle are snug. You might have to be careful when using this type of system with some carbon or more fragile rails as they could be damaged, and some irregular rails might have fit issues with the tight fit into the rail support. The amount of surface area with the yoke system that contacts the rail is very small, so this could exacerbate the interface problems.
I didn’t bother cutting the seatpost this time, since I wanted to see how it worked as a full unit. I am not sure if the extra length helps or if the seatpost has been slightly redesigned internally, but it felt stiffer while riding than my older one. I also think that the slightly larger bolts help just a tad with any flex issues (a seat of the pants feel). The larger bolts have also meant that I have had no squeaking bolt issues (until the other day) after nearly 5 months of use. The smaller bolts required more tender loving care and maintenance.
“I wish I had someone I could really respect. Hey, look at the cans on that bimbo!”
The weight saving on my current bike by cutting the seatpost would not be very much anyway (or is the anyweigh). I have been making my 5.5 inch full suspension weight weenie bike a bit more All Mountain these days, and depending on my current fluctuating build my Ibis Mojo can vary anywhere from 23-26 lbs! The 31.6mm x 400mm weighed in at 166.9 grams, which makes it one of the lightest seatposts on the market.
Length: 390mm or 15.5 inch

Rail Support: 11.2 grams
Yokes: 2 @ 5.8grams
Bolt: M6x45 5.4 grams
Bolt: M6x35 4.4 grams
Connecting Rod: 9.1 grams
Total weight: 166.9 grams
So far, the seatpost height markings have not been worn as much as my older Ti Pro Lite, and I am not sure if it is better marking method, or that they are on the back of the seatpost?
