I need a setback seatpost 27.2 mm, 27 cm or so. I've seen two main choices lately: the V-O two-bolt Gran Cru with Long Setback for $55, and the Nitto S-84 seatpost for about $160 right now at Rivendell. The Nitto setback is claimed 40 mm and the V-O is claimed 30 mm. From both companies "normal" setback posts are 15 mm to 20 mm, so these both give me more setback, which I need for Brooks or my Rivet.

The Nitto obviously costs nearly 3x the price of the V-O. How big is the quality difference between them, if here is one? i have a few of the Nitto and they have been good parts, but is anything lost if I buy the Velo-Orange instead?

Nitto S84 - $99

I've ordered from Alex's many times. They are legitimate with five day shipping to Atlanta from Osaka.

Track Supermarket has it for $100.

Thompson setback

I have used the S-83
https://www.universalcycles.com/shopping/product_details.php?id=18232&category=167

S-84 is steel.

I owned the VO, hated the bolt system and its slippage, ended up dumping it on eBay,

+1. The two-bolt adjustments allows to fine tune the tilt like nothing else I have ridden.

With 20-25mm of setback, a Brooks saddle pushed all the way back, is usually adequate. Why the need for this extra setback. Frame too small?

Two bolts, but side by side instead of front and rear. Unless your torqued the crap out of it one big pot hole would cause the saddle to tilt. Additionally, I found minor adjustments to be frustrating. I figured it would not be a keeper for the long run so I sold it before it got chewed up.

Strangely, I found a thudbuster was the perfect solution of rme. Lots of setback, micro adjustment, and suspension to boot. Big and heavy, of course. On another bike, the bent Thomson.

These problems had to do with using a Brooks B17. As I use Ergon pro carbon saddles on my fast rider bikes the set backs available are fine as is.

That S-84 is a nifty piece. I hadn't seen one before finding this thread. Can't help but wonder though why the need for that much setback? If you truly need that much setback to achieve a good knee over pedal position the seat tube angle on your frame is too steep.

# 1 V O is an importing seller not a manufacturer ..

Q: what do you understand about the strengths of different alloys of aluminum. .. ?

generally, How about this one.. ?


A Nitto chromoly seat post has significant setback

It's not a topic I want to address in this thread.

Fiets, which question are you directing to whom? what is your point regarding materials science, and regarding V-O? I'm pretty good at materials.

I made this one...

But alas when looking for a lot of set back that is usually a good sign of a poor fitting bike. Bikes that fit are great, bikes that need a lot of parts to try to make it sort of fit aren't so great. I get it though sometimes there is a cool old frame you see and it is fairly unique or sufficiently vintage that finding another in your size is hard but you might just let it go and find the bike that fits.

Getting that out of the way, Nitto makes some top quality parts, a lot of time cold forged for extra strength and durability and they really take a lot of time and pride in their work. The only thing one could say about Nitto is there stuff can be weighty but their goal is not weight but quality and durability.

Basically to BF level generalizations; aluminum various alloys can be like steel ; ..high strength use less , low cost use more. to be equivalent .. in practical, use,..

Maybe the guy has a physical issue where he needs setback.

Maybe he is experimenting and wants to learn for himself.

Maybe he doesn't feel like getting lectured by a bunch of people who never met him but knows exactly what he needs.

Maybe he wants what he wants and that's all there is to it.


My pleasure. I hope it works for you.

Is this an enquiry about non CF seatposts? Fwiw, FSA offers a K-force seatpost with 32mm of setback..

But ... Thompson clamp parts can be purchased from Thompson so a framebuilder with skills could make you a custom post of any setback using Thompson hardware. I have two TiCycles posts with aluminum heads and titanium posts, each with roughly 60 mm setback. Wonderful posts. (My preferred bike, no holds barred, has a tight rear end, 74 or steeper seattube (to accommodate the close rear wheel with decent size tires and fender. I want a setup that puts the clamp midway on my favorite seats so lots of options are available in the future. So I could go either curved seattube or big setback post. Maybe one day I'll spring for that curved tube.)

So, you have the option of ordering a TiCycles post of any setback you want with that first-class hardware. And being completely custom, everything, post length, material and diameter, finish, etc, are on the table. 2011 prices were ~$160 for mine. Their prices have gone up but not radically.

Edit: I hadn't read veganbike's post above yet when I wrote this, but I submit it now as an example that his generality isn't always true.
