Seat Down Vs Seat Up – What’s Actually The Difference For Mountain Biking?

October 6, 2019

♪ [music] ♪ – [Marc] Oh, my God, this is not a good
idea! ♪ [music] ♪ – [Neil] Most people have seen the light
nowadays and either run a dropper post or just manually move their seat
up and down, depending on the trail. A low seat gives you that space to move
around, and it makes it much easier to go faster. – [Simon] To be fair, though, I think
there are still a fair few of us out there that are hanging on to our old fixed seat
positions. I haven’t moved that in years and years, in fact, and I think I still
go all right down hills. – Si, you’re living in the ’90s, mate.
Even the World Cup Cross Country pros are running dropper seat posts.
You got to get with the program. – Right then, lads. Let’s fix this once
and for all. Si, you do a run with your seat down, Marc, let’s do a run with our
seat up. See how it goes. – Sounds dangerous. – All right, has anyone got a tape
measure, so I can make sure it’s back in the right place? – You’re going to be throwing your fixed
seat post away after this. You won’t even need a tape measure. – Right. Here goes nothing. – I’m not sure I like the sound of this. – Oh, my God! It’s really hard to get your weight back
on this particular bit. The seat keeps getting in the way, banging
between my thighs. It’s hard to pump and maneuver the bike. These rollers are horrible. Pedally section is coming into its own. I can stay seated, putting the
power down with the least effort possible. I can’t lean the bike over as I’d like. Jumping with your seat up is so dangerous. It just wants to smack you in the
behind and pitch you over the front. – Run number one. Seat post in the correct
mountain bike position. Now then. I will admit that on mega-steep
stuff, or even slightly steep, that having your post up kind of does get
in the way, but then I just rode all the way up here on a really nice light bike,
and my seat was in the right place, and now my seat’s where I want it to pedal
[inaudible 00:02:47], just like that. Now a bit of fire road,
seat’s in the right place. See, seat in the right place, no stress. – This is more like it, seat down! Straightaway, you can be way more
aggressive on the bike, hanging off of the
back, hammering turns. You can see I can lean the bike
over without the seat getting in my way. Pumping down these holes. This is going to be so much faster. I think even Si will be shocked. I’m sure we’ve smashed our
time with the seat up by at least 10 to 15 seconds. – Second run. Seat, God knows where it is. – Down [inaudible 00:03:57], where it
should be. – I’m not going to lie. It instantly feels
like significantly faster. I reckon if I practiced in this position,
it would get pretty bloody quick. Bloody hell, cornering is ridiculously
fast. [inaudible 00:04:29]. Now, that was a lot
easier. Really want to sit down and pedal,
but I guess it’s not allowed. I tell you what, I’m
out of breath. – Right then. So four runs later, we’ve
got the results. We haven’t seen them yet. Before we look, predictions, guys? – Feels much faster to me. You can move
your weight around on the bike a lot better, and especially cornering.
It feels like you can get your center of gravity much lower if your seat’s
not up. – I’m going to make a bit of a prediction
here. I think that Neil and I will be considerably faster with our
seat down, because it felt so alien riding with the seat up. You, Si, I
think will be…the gap will not be as big, because you’re not used
to riding with your seat down. So it’s going to be interesting. – All right. I think that’s a good shout,
actually. I think putting your seat down for the first time in 15 years,
you probably won’t quite get the same benefits as you would if you did it
more often. But… – Right. So I was six seconds slower
with my seat down. That’s a good shout. Right then, and you guys were…right,
hang on, let’s do some math. Seventeen second quicker with your seat
down. So in fact, now this is an interesting one. I was one second
slower than you guys with my seat up compared to you. – So there we go then. – Pretty close with seats up, yeah. – We could do seat-up downhill racing.
I might be all right at that. Anyway, so, there we go then. I think
you’re right, Marc. I think maybe I do need to get used to having my seat
down, because actually it did feel quicker. It felt significantly
quicker. Like you said, you can get lower
in the turns. And so I was able to get my body
into positions that I can’t normally do. And also, when we actually picked up a few
shots after our runs, I also nearly crashed, and there’s no way
I could have held it up if I’d have had my seat up. But I was able to kind
of… – Do you think that the reason that you
were faster with your seat up was because of how efficient your pedaling was,
and that was your Achilles heel on that run? – Yeah, I think so, actually. The run
was one of two halves, wasn’t it? So we had a steep non-pedally bit,
and then quite a flat pedally bit for what? A minute or so, at the bottom?
And so I reckon being able to sit in the saddle…I certainly didn’t feel
half as pumped when I got to the bottom with my seat up. So yeah, maybe
on a different run it would have been no contest. But yeah. Anyway. I did…
I did think, actually, if I could, I would get a dropper post, possibly. – Converted. – Yeah. You guys make it look good fun. What do you think? Drop a post.
Seat down? seat up? Let us know in the comments. – And don’t forget to subscribe to GMBN. – Yeah, that’s a good point. Subscribe. I reckon they could watch some other
videos, as well. If you click over there
and up there, explaining some good links. Click on them.
