Post Moderne Bracer sus post

Another question: I see separate Post Moderne spring/elastomer sets are available. What model are
these for? If Bracer, what version is supplied with the post as standard: hard, medium or soft? (Of
course I would expect medium but I dunno). Or does this model not have any alternative sets because
it's adjustable?

re replies on Post Modernes: Please indicate whether you're referring to MTB or Road version.

What is the minimum amount of exposed seatpost required for the Bracer seatpost? In other words,
how long is the suspension bit at the top?

On mine the absolute minimum distance you could get from the top of the seat tube to the bottom of
the saddle rail is 115mm. Remember though that it compresses when you sit on it so the actual
distance to compare with your current set up will be less than that.

Thanks very much Tony. Is yours the "MTB" version (tinyurl.com3do7pOpen ↗) or "Road"

MTB according to that, although it was not differentiated as such when I bought it. I remember
looking at both and going for the longer seatpost version and rubber gaiter but there did not seem
to be a lot of other difference

Update: I've bought a Post Moderne Bracer Road post. No problem with minimum height: that's about
9cm minus static compression. One on-road ride so far. This is the first suspension seatpost I've
tried so I've got nothing to compare it to. However, I was expecting more for my fifty quid: the
suspension effect is very subtle, and I've got it on the softest setting. I've been told layback
types like this "don't work" and I can now imagine what they mean (although I don't actually know if
suspension effect of inline ones is any different). It is at least better than too much boinginess,
and the /slight/ softening of the ride that is present all the time is better than a kick up the
[censored]! Saddle clamp is a good two bolt type.

Only downsides now I've got it (because preload can always be maximised if suspension not wanted) is
the small amount of extra weight/maintenance and extra attractiveness of post to thieves.

Pete,

A word of caution about the said post.According to the instructions it advises stripping it down
from time to time to clean/lubricate etc.However if you remove the two rubber ' top out rings ' ( I
think that is their name ) to enable you to remove the inner post ,you can't put them back for love
nor money and there is an [censored] jarring thump everytime you go over a bump as it bottoms out.I had to
send mine back to Taiwan to have them replaced by machine ,they admitted there was a problem.I have
had mine for a couple of years so the design may have changed,but be careful.

Thanks Sam. I couldn't live with the suspense so I had a go at rebuilding today. I did eventually
figure out a way of putting the top-out rings back but I'm not sure I've put them in the right
place!!!! Can you describe where you think they should go? The exploded diagram in the instructions
is ambiguous because the rings are able fit over and through other parts so I can't tell where their
resting place is from that.

Pete,

With reference to the diagram in the instructions and on the site ( postmoderne.comfaqOpen ↗
index.htm ) the top out rings go on the inner post just under the hexagonal bit.IIRC there are
places for them to fit.The problem was that with the inner removed from the outer and the rings
fitted the inner wouldn't go back into the outer ( too wide ).If you put the inner back into the
outer without the rings you couldn't fit them as they needed to be fitted at the top end of the
inner which you couldn't get to.It sounds awfully convoluted I know but the rings are supposed to
act as shock absorbers when the post ' bounces ' back up to its normal height. As I said in my OP my
post is a couple of years old so the design may have changed although looking at the diagram on the
site it doesnt look as if it has. If you do take them off and struggle to refit them be careful as
they are a bit fragile,I split both of my rings trying to put them back. The annoying thing is that
on Page 6 of the instructions it tells you to separate the inner and outer !! If you manage to get
the rings back OK let me know how you did it I would be interested to know.

Hope this helps,

Sam Salt

The inner shaft doesn't have any grooves or special places but the rings do happen to fit on it -
both immediately under the hex section and on the small bottom end.

I found the same problem when I tried to fit them there like that.

Wouldn't they effect bottom-out if fitted at the top, though? Maybe I'm getting "bottom-out" and "top-
out" mixed up (maybe even Post Moderne have!) but the boot by itself acts to prevent a clunk when
inner shaft goes down all the way (although I can believe this isn't considered adequate).
Fortunately this won't be an issue for me as I'm unlikely to bottom-out.

Are the two rings supposed to sit together in the same place? Why are there two of them instead of
one thick one, I wonder?

I ended up thinking the rings were supposed to pass through the upper bush or be fitted from
underneath, so, in my confused desperation, I dropped and poked them into the bottom of the outer
tube after inner shaft was in but before fixing bolt was fitted. Some careful prodding with a
screwdriver positioned them on the the lower bush guide (I think). Seemed to make some sense at the
time although I'm not sure if it's done any good* ... or harm! Oh dear, I'm still confused. The
penny might drop later with any luck.

* A clunk can be heard and felt when saddle is pulled up sharply but there's so little compression
and so much friction that the post doesn't pop up forcefully enough in normal use to cause noise
anyway - so I'm not bothered unless anything gets damaged.

Yes it does get confusing I must admit.Both rings sit next to each other

AFAIR,like you say why not one ring.By ' bottom out ' I meant when the inner post comes up as far as
it can.The rings stop it thumping.I think what you meant was when it goes down as far as it can. You
are right there is a lot of friction and it doesn't slide like I think it should do.Another thing as
well.If you have a lot of post showing ( beyond where inner is ) and you tighten the seat bolt tight
it doesn't move at all .Presumably it must sqeeze the outer a little inhibiting movement. I must
admit I don't think I would buy another.
