Rollerski questions I cannot find answers for

Lots of helpful answer already! To msummarize, these question remain
(partially) open :

*1* Race rollerski's.
Why are 2-wheeled race-specific rollerski's "all" 530mm axle-to-axle?
Fast, easier, safer? I can see it being lighter.

*2* rollerki vs. leg length
I have a 995mm/39.17" inseam. Should I look for long rollerski's to learn
technique the best possible way? Could the V2 Aero 150 Combi SC's (27"
axle-to-axle) work for me, skating-only? Their skate-specific version is
24". Aero 125 (I'm too heavy for those) is actually longer than the 150.
Also if I end up making my own, it will be good to know what is going to
work best.

*5* Brakes.
Apart from speed reducers and V2 Aero add-on brakes, are there any other
good speed killers? Documented home built decives? I'm not exactly very
graceful with wheels stuck to my feet and traffic is crazy around here, so I
want to be able to stop when I feel unsafe.

*7* WWW.
Any rollerski forum anywhere in the world I can tap in to? From cycling I'm
used to just read and read till i can answer all questions myself, but it's
so hard to find any rollerski info, like it's all in-crowd. Websites are
very outdated, just thumbnail sized pictures, etc.
I think I've got links to all manufacturers in the world now, don't need
those anymore, thank you.

*9* Heartrate.
I can't get my heartrate close to threshold (~10bpm) yet, doing mostly V2alt
as that's what I can manage. Can't climb good enough yet to use my cardio
system. To get my heartrate up, should I "just" increase effort, to what
seems like a sprint? Or train more and hope to build stronger skate-specific
muscles that suck the air out of me?

1. Wheels are the determining factor for racing. As a novice you should
get the slowest wheels possible. Rollerski chassis come in varied
lengths. With your foot size I would go longer than 530mm. 530mm is
used by elite racers because they are lighter and more maneuverable.
Marwe makes an excellent rollerski with a length of 610mm.

2. Leg length is no factor when choosing rollerskis. I would be more
concerned with weight.

5. Snow Plow! In combination with the speed reducing mechanisms you
have mentioned. Here is a website with video on technique and stopping.

9. You should be able to get your HR to threshold with no problem from
V1 to double pole. I have trouble keeping my HR low when I rollerski.

"maneuverable", how should I see that? More freedom for movement in turns,
or making a rollerblade-like skating motions?
I am looking at 150mm tubeless air tires as my main rollerski wheels to
learn the technique and have to pick the cleanest of road. For days in a
hurry, 125-145mm PU wheels. But only if I can control that speed.

2. Leg length is no factor when choosing rollerskis. I would be more
concerned with weight.

My current Crosskates are 3.7kg per foot, including all. I'm not into
rollerski racing yet, so as long as they're not much heavier than I can
expect from skate ski's, I'm fine.
In ice-skating the blades go up in length a bit with every shoe size I
think, as do ski's. I wonder why that doesn't work with rollerski's, apart
from having to acommodate a boot size?

5. Snow Plow! In combination with the speed reducing mechanisms you

Thanks, I've seen that video yes, and somewhat put it in practice already
beforehand, having seen ice skaters do it on tv. Judging from the time it
takes here to come to a stop, she's travelled about the length of a block.
Not very practical to avoid problems, I fear.
I really hope there's better brakes out there. Powerful stops. Abrupt
decellerations.
A dog jumped in front of me this week, and I really had no-where to go. Next
ride I'll use long baseball bats for poles, so I can clean the road in front
of me :-)

9. You should be able to get your HR to threshold with no problem from
V1 to double pole. I have trouble keeping my HR low when I rollerski.

I stay 30 beats below threshold easily when just going for a ride, trying
not to look slow.
Perhaps I have difficulty because I've got pretty powerful lungs to start
with. Near untrained in the off-season I was tested to have 506W of aerobic
power. I am probably putting out 300W now when trying hard. I'll try even
harder this evening. I guess it just takes strong muscles to get the
heartrate up.

Are crossskates decent on gravel paths?
Do they tend to jar the fillings out of your teeth like rollerblades?

I'm sorry, but I lack comparison. Never bladed, too scared for hitting the
perfect asphalt it requires.
I've got my Crosskates on OVER the recommended 60psi, which I don't
recommend for dirt especially. I tumble more than I roll over it, or perhaps
I should put my weight further back.
What irritates me most on bad pavement and gravel is how the front wheels
will pivot due to sideloads from imperfections. Wobly wobbly.
If you see the video's on the webpage you can tell it's all just my setup
and especially technique. I can get the brakes to do brake better than a
loosely dragging pole. In the video they come to an immediate halt, after
bombing down a rough gravel road. Oh well...

Over worn asphalt with not too large marbles, they roller very much like on
perfect asphalt, no drama. The tours I'm doing now would be very impossible
on blades so the same for currently available PU wheeled rollerski's I
guess.

There are good reviews all over the web for the V2 Aero 150mm rollerski's,
read them, they might be sufficient for your dirt roads. As the wheels are
smaller, the boot may be located more aft on those than my crosskates,
making the front wheels less loaded, and easier to roll over road debris. I
would not have minded if the crosskates had been longer in the front. Just
skating along the front wheels are already too loaded to not try to steer
back in as I skate out. I'm already using quite stiff steering springs,
carving a corner without stepping really takes a lot of road. Nice for
narrow downhill flowing cycle paths, otherwise mostly cumbersome for
rollerskiing any less than alpine-style.

Bob, I thought you didn't use your poles while skiing? ;-) Where did
all this knowledge come from?

Seriously, make sure that the straps are tight enough so that you can
let go of the pole when you follow through. This is one of the the
keys to a long stride (Bob, are you listening)?

What do you mean by this?

I changed my straps yesterday, and comfort was immediately better. Aero tuck
very easy and natural, where before it was quite complicated. Had to get
used to the strap giving me "feedback", but it's fine now. Also the straps
seem to slip much less now they're tensioned under a lower angle, very good,
they slipped through the grips on me all the time, what-ever I did to
prevent that.
With tired limbs from the day before I still bettered my PB over 1000m even
letting go for the last straight, perhaps thanks to the correct straps setup
giving me a more natural skate. Thanks again @ Bob!

I read it in a book. er, actually, I just looked at the pictures. No,
someone else looked at the pictures and told me about it ;-)

Jan: ignore this. It's about striding, not skating.
bt: Another key to a long stride is to get out on the trail early so that
the snow is consistent :-( Last weekend, I had grip on the shady parts, but
not in the sun. Rode Super blue (my new crap-snow wax) doesn't work so well
at +4C. Skating on my classic boards, again.

I agree with bt that it is important to have your straps correctly
adjusted. If you are using the same style of strap as shown in Bob's
pictures, then if you hold the pole normally then push your arm all the
way back, you should be able to hold the pole in the air with your palm
open (see pics below).

Regardless of whether you are doing classic or skating, it is important
to allow your arms to have a complete extension, including a proper
wrist flick at the end.

I've never heard of such a thing! Downhillers put their hand in the
strap the same way XC'ers do
