Other than thomson – what 400mm seatposts are there – cheaper the better! Lightish please

CRC Brand-X do a 400mm post. Cheap but heavy, very heavy.

Superstar did a 400mm carbon post but I think they've stopped selling them.

On One Twelfty are good

needs to be lighter than the scaffold pole i have

U.S.E. sumo?

I got a cheap 400mm "push" one from JE James, 330g not the greatest clamp but at a quarter of the price for a Thomson I'll live with it.

EA70 for a big geezer here. Been using them for years. Never a problem, and I'm not very 'subtle' (read good/light/skilled) on a bike.

most U.S.E posts come available as 400mm rob…

cool – sommat go go at 🙂

Another vote for On-One twelfty. Machines from billet and lighter than thomson. Just happen to have one for sale after my recent 575 purchase as it needs a 30.9

how much?

There's some on ebay, most appear to be Kalloy ones, I have one, it's not light as such, but at that length I prefer a bit of extra metal.

Funny story, I was actually after one between 500 and 600mm, but no one does them, so an hour ago I chopped the head off one, fitted a QR clamp and inserted another seat post. I now have up yo 800mm of seat post, which should do the job.

Raceface do various 400mms, I've got a Next 400mm post somewhere. Or gravity dropper 😉 On One Twelfty is probably the sensible choice mind.

There's a ritchey comp one on CRC which is pretty light and 400mm I think

That's a joke right? I can never tell on this site.

woop only need 350mm – the oem one is 300mm 🙂

Syncros do a 400mm post, you can find them on the Stif website.

Used Ritchey:bent it.

Wtb TXC a solid post with layback.

Nuke pRoof warhead was nice. No layback.

In fact my txc is up for grabs. 30.8mm for specialized.

Thomson

cheaper the better!

I have one. It's very nice 🙂

Nuke proof do a 400mm I think, it might even be 440mm.

They're a similar design to Thomson, but not quite as good, but cheaper, and still good.

No, no, I have a bike I've built up, put a 400mm seat post in, but it was a couple of inches too short for pedalling up hills. The new 'arrangement' is probably stronger as now I have 8 inches inside the frame and only a little extra length. The seat post is pretty beefy, being a 31.6mm thats 3mm thick and it's only on full height for pedalling up climbs and I'm stood up on the DH bits. Will get you a picture and let you know if it snaps!

Bontrager do them (in 27.2 or 31.6, with 5 or 25mm offsets). I think mmine is called a Race X-lite. Its an ACC (alu. core construction) one
