Answer of John

Yes, the 25mm offset post will definitely deflect vertically moreso compared to the 0mm offset one, which will results in a slightly more comfortable ride. "The straight post is loaded primarily axially, or directly in line with the post in compression. The setback post has a combination of loading both axial and bending. Since most every structural material will be stronger in compression than bending. The straight post will have virtually no deflection when loaded, the setback post on the other hand will likely have a subtle deflection (change of shape) that can lead to a bit of shock absorption." That said, I have the 0mm offset one, and while it doesn't deflect much vertically, the little bit of horizontal deflection actually dampens the ride a bit because the seat tube angle isn't perfectly vertical (it's 70-something degrees instead of straight-up 90 degrees).

Answer of Harrison

there is no room inside the seat post for holding anything because it is separated into two parts instead of one internal space

Answer of Craig

The material making up the post is fairly thick, leaving little if any space between the two halves below the point of insertion. So, no, I don´t think you´re going to be able to fit anything inside it.

Answer of Davide

Good morning, since the seat tube is made up of two crescent-shaped elements to guarantee damping, it is not possible to insert any pump inside as the tube is not round.

Buongiorno, essendo composto il tubo sella da due elementi a semiluna per garantire lo smorzamento, non è possibile inserire nessuna pompa all´interno non essendo il tubo tondo.

255 mm of seatpost at minimum insertion for the 350mm seatpost.

255 mm of seatpost at minimum insertion for the 350mm seatpost.

Answer of Colin

I did just that but glued the 31.6mm spacer in as mine was creaking. Make sure this seatpost sticks out no less than minimium markings so it not impede the flexing function of the seatpost.

You have to buy an adapter to fit oval rails.

Maximum insertion depth leaves you with 152 mm (15.2 cm). 255 mm of seat post at MINIMUM insertion.

Answer of Colin

There is a printed scale on the seatpost for min/max insertion of the seatpost in the frame. I have the zero offset model but the offset version is the same, they require a minimium of aprominately 140mm or 14cm sticking out from tube in frame to centre line of pivot bolts to operate. So in your case being 110mm or 11cm, it will not have enough.

Answer of chris

There is no specific weight adjustment. The only adjustment is the lean angle.

Il n y a pas d ajustement spécifique au poids .Le seul réglage est l angle d inclinaison .

Answer of Colin

The seat post is not adjustable for weight. The adjustability is for the seat angle only. You set up seat angle & seat height as you would set up a normal seatpost. Note, The two leaf springs flex & provide good comfort, more than a normal seat post. The maximum load when fully extended is 100 kg or 220 lbs.

Answer of Colin

Yes, the one advertised here is a zero offset/ zero setback. But they sell both zero & offset. If it's straight in the picture of the product it's zero offset, if it's curved at the top, it's the offset type.

Answer of Colin

No, the seatpost does not have a hole in the centre, it is actually made of 2 solid pieces of carbon that can slide against each other for adjustment & flex purposes.

Answer of Edward

It’s round and fits standard seat rails.

Answer of Colin

The flip head comes for round rails only but you can purchase an oval head seat clamp version separately, is easy to replace.
