I´m planning to buy one but as I live in Brazil I need to know in how many
boxes
the Actionbent comes and what are the boxes sizes and weight so I can figure
how much it will be to ship to Brazil, I´m planning to delivery in a friend
house in
US an then mail here.
For those who bought it please send me details about their boxes, thanks.

Dear N & Peter,
It's common to assume that recumbents have an aerodynamic advantage
over the traditional diamond frame, but the advantage is actually
limited to fairly extreme recumbents.
You can see some of the surprising details on this speed calculator
page:
http://www.kreuzotter.de/english/espeed.htm
Hovering the mouse over the radio button for the type of recumbent will
pop up a picture that gives an idea of what a particular model looks
like. After selecting a model, clicking on calculate at the bottom will
give a predicted speed for the default values and the drag area used
for the calculation.
mph frontal type
17.1 4.3433 recumbent long wheel base
17.3 4.7889 df hands on tops
18.5 3.3781 recumbent short wheel base
19.4 3.2559 df hands on drops
20.5 2.7111 df triathlon bars
21.2 2.1748 recumbent short wheel base racer
22.3 2.0397 df superman position
23.1 1.5504 recumbent lowracer
Obviously, these are idealized guides to what a particular bike and
rider will do, with different tires and transmission efficiences
affecting things. But for the same rider and power, it takes a
recumbent that stresses speed instead of comfort to improve on the
aerodynamics of an ordinary diamond frame:

"It's not about the bike."
You're correct that the differences are not as large as people
might imagine. People who try a recumbent and think they will
automatically be 10-20% faster *will be* disappointed. It depends
on what you're comparing, but 3-7% without going"extreme"
is quite possible, however.
Note that the default tire choices on the kreuzotter website for
non-race configured recumbents are medium and wide. The df
tire choices are all high pressure, by default. Here's the list
with the high-pressure tire choices for the LWB and SWB
added**.
mph frontal type
17.1 4.3433 recumbent long wheel base (medium slick tires)
17.3 4.7889 df hands on tops
18.0 3.8777 recumbent long wheel base (high-pressure tires)**
18.5 3.3781 recumbent short wheel base (wide slick tires)
19.4 3.2559 df hands on drops
19.5 2.8408 recumbent short wheel base (high pressure tires)**
20.5 2.7111 df triathlon bars
21.2 2.1748 recumbent short wheel base racer
22.3 2.0397 df superman position
23.1 1.5504 recumbent lowracer
It's also worth noting that the two non-race configured recumbents
modeled above are under seat steering. Most recumbent bikes in
the US are above seat steering. The "recumbent short wheel base
racer" may cover many of the so-called "high racer" recumbents
(Bacchetta, Volae, RANS...) and these may not be considered
"extreme" or sacrificing of comfort.

Note for this discussion that a Speedmachine would probably be somewhat
better than the "ShortWheelBase, above seat steering, racing equipped"
but not as good as "Lowracer, above seat steering". That assumes it's
the ASS SpM rather than the new USS option.

But you've got to check the gears, too, afterwards, to make sure
they're shifting right and all. I don't think they did too much of
this, though...he probably checked for half a minute!

Now now, we all know about names and keting...but I didn't know 80%
of effort expended in on behalf of air resistance! Still, my point is
that I should be at least as good as a DF, given my better aerodynamics
on the SMGTe, but that's not been the case so far...even given my
Schwalbe athon Plus tires, the hit seems too big...I can only hope
it's a matter of developing the muscles and riding technique, as well
as those nagging chain issues (chain hop, chain suck, stiff shifting,
no shifting...it's rideable, but not smoothly so, especially for a new
machine with brand new components).

Yes, I knew this going in, but I figured that I'd rather have more
puncture-proof or puncture-resistance than speed, if the penalty isn't
too large and way out of proportion.

This is fair comment, but 30 seconds should be enough in the first
instance, which still leaves us rather a lot of time. Tweaking the
gears is easy enough with the adjuster screw where the gear cable
goes into the rear mech, just needs the odd tweak to tune the shifting.

That is, IIRC, the approximate figure on a DF, though I can't
remember if that's on the hoods, in a heavy tuck or what. But it
does show approximately the degree to which speed is dominated by
aerodynamics any time you get any sort of fast.
> Still, my point is

They're not /that/ much better. I have my seat reclined as far as
possible and it's pretty clear that cycling with pals on DF leaned
over the drops that the frontal area catching the wind isn't all
that different. When they go into a full speed crouch it's quite
obvious they have less frontal area than me.
If you want better aero, that's what the Speedmachine is for (and
to some extent, the Grasshopper).

To put the dangers into perspective, I've had 2 punctures on mine
in 5 years running standard athons. They give very good
puncture resistance. The M+ is only really an issue if you're in
Puncture Hell, otherwise they'd be standard issue rather than the
plain athon.

He still knows more than me! And when I say "cool," I mean that I can
ask why he's doing something, and suggest some other way of doing
things, and he ain't offended...very easy-going personality. I can ask
questions, learn, and he didn't seem to mind. Of course, I keep it

just get the sense I'm not dealing with a frustrated amateur racer,

No, I guess not...I didn't know how long it was supposed to take. But
surely you exaggerate with your claim of 20 seconds! Fixing a flat is
like five minutes, and surely cutting a chain (and then making sure
it's working right thereafter) is at least five minutes, too?
> No idea, I don't have a speedo and I'm not really that interested.
I just hope I'm not more than 3 mph behind my DF on the flats -- bad as
that is (a mile is like 20 NYC blocks...3 mph less would make me a
whole neigbhorhood or two behind after an hour!).
> If you want to go faster, that's what the Speedmachine is for...
I seriously doubt the SpeedMachine is that much faster...it's certainly
the same damned weight! Yes it's even more reclined, but no big deal.
I can't wait for HP Velotechnik's new machines...I'm guessing it'll be
another year or two....

I wasn't timing him, but I think that's a fair guesstimate. What you
have to do is wind in a lever 3 times (once for each end of the break,
once to reconnect the two ends.
> Fixing a flat is

Fixing a flat generally means removing the wheel, unseating the tyre,
removing the inner tube, putting in a new one, reseating the tyre,
replacing the wheel, reinflating the tyre. That's a much bigger to-do
list than doing up lever to remove one pin, removing another, popping
one pin back in.

No, very big deal indeed. At 18 mph about 80% of your power is
overcoming air resistance, and there's significantly less frontal area
to catch the wind on a Speedmachine. There's a clue in the name!
> Oddly enough, the tires say that maximum psi is 70-lbs.!!!
I'd assumed, incorrectly as it turned out, that the M+ would be the same
dimensions as the plain athon, but looking at the specs they are
fatter and run at lower pressures. So they will probably be slowing you
down :-(
For a still reasonably puncture proof and capable touring tyre a swicth
from the 1.75" M+ to the 1.5" athon running at higher pressure will
probably help you with rolling resistance and hence speed you up.

I do (regard the mechanic hesitantly), because he seemed to be the kind
of backyard mechanic my friends are -- "good enough for government"
quality work: I told him there was a gold-colored link in the chain,
but he just undid it somewhere arbitrarily, and while joining the chain
again he didn't use the chain tool at first, but a regular
whachamacallit, that hand-held "vice" with the scissor-like
construction...while shortening the boom he used a rubber mallet but
still no cloth over the bike until at my suggestion...little things
like this.
But, to be fair, a good quarter of the time he was struggling to get
the chain back through the teflon tubing since the whole line slipped
off. =) And he hadn't worked on recumbents before, so perhaps the
novelty of it all, even though a chain is a chain is a chain, had him a
bit distracted.

What's a "stiff" link?
I'd never had a chain follow the chain ring back up, ever!
> But again I gasp in horror... 20 minutes to shorten a chain!? :-0
Yeah, and I'm really not exaggerating. But I am referring to the whole
process involved, from undoing to redoing, and at least 25% of the time
was spent trying to "thread" the chain back through the teflon tubes
and underneath the idler (that big flywheel, right?).
Nothing compared to 20 seconds, for sure, but certainly far better than
I would've been able to do, not having heard of chain tools until just
yesterday! And now, having seen it once, I at least have the framework
against which to gauge my own attempts.
Yep, I always knew a 'bent was gonna mean hands-on...just didn't expect
it quite so soon!
What's the fastest you can run yours on the flats?
At the middle gears (front and back), I seem able only to acheive 16-17
mph! This is what I do leisurely cruising along on my DF!!!
I do have on them Schwalbe athon Plus tires, though....

Just what it says: links should move completely freely, but a stiff

So we're still at 15 minutes to break a chain in a couple of places and
pop it back together, which is still not very good.

Shouldn't be /that/ much slower than the plain athons I use. Make

Nice!
But again, I lack the basic context necessary for such information to

So in the interests of expediency, I chickened out. =)

Well, I kept the cut chain links and will be practicing, all right!
But my chain "sticks" on the "aftermath" -- once it's made the round of
the biggest front gear, it tends to "stick" onto that gear and follow
it back around again! This only happens on the biggest front gear and
the smallest rear gear for some reason...will need to visit them again
soon! But I'm glad I went, as those guys were cool (actually, 99% of
bike mechanics have been cool, if not 99% proficient 99% of the time)
and I expect to see them for other needs in the future.

Oh dear. I'd regard him with quite a bit of suspicion, to be

He had it down to about 20 seconds. Now, practice makes perfect,
and /I/ certainly couldn't do it that fast, but 20 minutes to
shorten a chain? There just isn't any excuse.

If the chain itself is running smoothly with no stiff links this is
likely to be derailleur adjustment, I'd guess.

old bit of tat chain (bike shop reject, local dumpster) to practice
on then you can be sure you won't miss when it comes to the Shiny
One! ;-)

Boom adjustment doesn't have me worried -- it's all the issues with
doing the chain...tension, length, and strength...I don't want to not
do something right and have a catastrophic, if not also fatal, failure
some time later....
There's a bike shop nearby but the guy on the phone sounded like a
drone and very bored (another LBS with an attitude problem).
Interestingly, he said cutting a chain is only $5. I would have
thought it'd be a bit more, seeing how it's probably as annoying as
fixing flats.
Still, I'm intrigued...it seems simple enough...find the Powerlink,
undo, remove another few links, redo Powerlink, and voil=E0, =E7'est ca!

Huh???? How's that possible????
X-seam determines how much to telescope the boom, which in turn
determines chain length, etc.

I'll get one, then, for the future.
But in the here and now, I've got the chain tool on the Topeak Alien II
Folding Multi-Tool ("Swiss Army Knife"). Is that adequate?
My real problem is expertise. Haven't ever done this, and don't want
to make a bigger mess of things.
I wanna ride already, damn it!
But sure enough, it's rain and threat of rain this weekend.

Shorten the boom first and see how your gears do. If they're skipping a
bit on the small chainwheel you need more tension, so a shorter chain.
According to how much the boom shortened, take out almost as much chain
and try again. Continue tweaking until the gears work smoothly at top
and bottom ends.
Strength is a non-issue. As long as you use a decent chain tool like
the Park one you can't appreciably weaken anything and the rivets will
be set in at the right place automagically.
So no reason for a failure later, and you'll know how to do it next time
and have the tool for the job if you /do/ have a failure.

It takes, oooh, several whole seconds to break it in the first place
(whether using the Powerlink you have or in any link with a chain tool),
and a few more to knock out the surplus bit, and a few more to connect
the ends back together. No parts needed, just a few seconds doing up
the tool. You can have the foolproof tool for not a huge amount more
than it'll cost to have it done for you.

Yes, it really is that easy. And since the chain's new finding the
Powerlink will be very easy as well... The key to undoing the
Powerlink, btw, is to squeeze the opposite plates together at the same
time you push the ends towards one another.

But you don't need to measure anything, just leave it loose after
pushing it in, sit on it, push it out to where you want it with your
feet on the pedals, make sure the crank is vertical, do up the bolts.
One perfectly set boom, no need to have any idea what your x-seam is.

Yes, but it probably doesn't automatically limit the end-point so
without a bit of practice re-insertions of the pins can be slightly off
and result in a stiff chain. Just a case of fiddling with it back and
forth until it's right, but without the practice a real mechanic gets
it's easier to have one that sets things right like the Park one.
That's why I got the Park one.
Pete.

Thanks for the well wishes -- my bike came in very good condition. You
do realize I bought an HP Velo SMGTe, right? There was a small scratch
the size of two commas or periods in an out of the way place, but
otherwise everything looks shiny and new.
Only problem is, it's too big!
I mean, the chain and boom...my x-seam is indeed 42" but I need to lose
another three inches so that I don't lock my knees and "tiptoe" on the
pedals -- and even then, not really!
@#$*%^&!!!!!
There's a guy at work who volunteers as a Ride shal every year at
the big Five Borough Bike Tour...I'm gonna ask him if he is any good at
cutting a chain.
I'll be starting a new thread on the bike once I've put in some miles
on flats and hills, in parks and on streets, alone and with traffic, by
day and night! Can't wait.
God this is getting a bit anti-climactic here....

The boom is secured by a couple of bolts. Undo them and slide the boom
in until it's the right length for you. You'll probably need to take a
bit of slack out of the chain: undo the Powerlink, take off a few links
from the end and then try again until the gears are running smoothly in
all the extreme ratios.
x-seam isn't very relevant to the Streetmachine unless you're very, very
tall or particularly short.

Get a Park Tools mini chain tool. They're designed to be foolproof and
IME of setting up an SMGT chain (I put a new one on last month, made
from about 2.4 standard chains) they've managed their design goal. And
you'll have a good chain tool for the future.
Pete.

Glad it ain't just me -- my HP Velo SMGTe was somehow "overlooked" by
BAX Global, so it won't arrive until tomorrow afternoon.

I just got my answers from the dealer, no more doubts.
I think I´ll order mine very soon, I hope your bike is ok and
nice to ride after a long trip.
tell us a review about your new bike, is it good?
