- Welcome to this week's Ask GMBN,
and it's a special one, I think, this week
because we're joined by Steve Jones
from EMBN.
- Yep.
- Steve, nice of you to be here.
- It's nice to be here.
I'm just thinking it's just like being
back in school. I mean, all this stuff
on the desk here Trisha for Gary.
- It does not say Trisha for Gary right there,
okay?
- Okay. Gary for Trisha.
- Gary for Trisha. Yeah, it is a little bit
like that. The shed is a little bit real
at school.
Right we're looking forward to answering your
questions that you've sent in to ask.
I'm going to get straight into it,
see if I can stump this guy. He knows his stuff.
- I'm already stumped.
- Let's get into the first question
from Domagoj Rajn, and it says,
Can skiing goggles be used for, be good for MTB?
- Are they going to be any good in the dirty
brush woods with a kind of tinted lens?
I'm not so sure.
- Yeah, they can be dark, can't they?
But I reckon, I reckon on a bright, sunny
day, you could get away with skiing googles.
- Can do. One thing I would say,
you need to make, be careful they do fit
in your full-face helmet.
- Yeah
- That's if you're wearing a full-face helmet.
- Yeah, you might be one of those guys
with open face goggles on, smiley, smiley
cheeks.
- Bandana
- Yes, bandana. It could work. It could work.
I remember the first day I went out
riding with riding glasses, riding cross country,
and this was a long time ago,
and I'd resisted. I'd resisted, and I thought
I'd try it and see what all the fuss is about.
All these people, their stylish glasses on,
and it was a revolution. I was like, oh
it makes so much difference. My eyes weren't
streaming with water, and ah, it does make
a difference, covering your eyes.
- I think it actually, it does, looking
after your eyes is a good thing to do,
I think.
- Yeah
- Generally, in life.
- Totally. In real life. Yeah, so we're saying
you could do it. You could do it.
I think Steve thinks it's a bad idea,
but I think he'd get away with it.
Although, you will have someone come up to you
and go, are those skiing goggles?
And I'm not sure that's a good look.
Right, Solden Stoll says,
Will starting mountain biking with a backcountry
and competitive freeride skiing background allow
you to progress faster on a mountain bike?
Well, that's an interesting question, that one.
That's an interesting question.
- Miquel Pasquale, I mean, one of the greatest
World Cup Downhill racers ever,
he's come from a huge ski background,
and he's won two or three World Cup Downhills.
- Yeah, Cedric Gratzia, also around the same time
rider, right?
- Yeah, kind of mid to late 90s.
- Yeah, both ride some.
- Yeah, I think it depends on your mindset
really.
- Yeah
- I mean, it is possibly a transferable skill.
It has been shown.
- Yeah.
- But only you know whether you can do it
or not.
- Yeah, I mean, I'm sure there's evidence
of a backcountry freeride skier who's terrible
on a mountain bike. I'm pretty sure there
must be that guy out there.
- Yeah.
- Um, but I think if you've got a sporting
background of any kind, and you've taken
a sport to a point where it's really tested
you, it's always going to be an advantage.
It's always going to be an advantage
into any sport you go to next.
Um, but, yeah, there is evidence out there
that there's some racers who have definitely
progressed quicker because they've done
a bit of skiing.
- You could do some bowls as well
if you wanted to. You could do anything
you wanted to, anything competitive.
- I feel like you've found the one sport
that maybe wouldn't help you into
go mountain biking. Bowls.
- I don't know.
We move on to the next question.
I feel a bit scared in this ask GMBN room.
- It's the shed. It scares a lot of people.
- It is. It's quite intimidating.
- It's scary. Um, little Dan Lloyd.
Your Dan Lloyd, he's intimidating.
Um, Villageinvader Films says,
Can you use a 27.5 wheels on a 29er bike
or put a 27.5 inch fork and wheel on a bike
that comes standard with 29?
Um, so what's the guy's name?
Or her name again?
- Villageinvader Films
- Well, you can put whatever size wheel
you want into a 29 inch wheel bike, but
you know what? There are a lot of bikes
out there, I mean, the specialised enduro,
there's a wide, they both have 29 inch
wheeled bikes, you can fit 27.5 in as well,
and what it does ultimately the bikes
with the 27.5 inch wheel's got a better
geometry, but you need to be careful.
You don't want to get the bottom bracket
too low to the ground.
- So you said on those bikes, the bikes
where you've got the 29 inch wheels,
it's working out the bottom bracket
is actually too high?
- Well, you want the really the sweet spot.
For example, the bottom bracket might be,
you know, round about 345 or something like that
and then go down to 338 or 327.5. I think
on like a 160 bike, a downhill bike,
338 millimetre bottom bracket is the bottom
line there really.
- Right.
- But you do want to be riding your bike
with a 360 mill bottom bracket,
so ultimately it depends on your bike.
It depends on the tyre size as well.
- Yeah.
- It depends on your forks. That's a huge, huge
question. We could spend the next week
talking about that if you wanted to.
- I'm going to have to stop you
from doing that.
- Sorry.
- I'm going to have to stop you
from doing that, and we're going to move on
to the next one, but good answer, Steve.
Like that one. Like that one.
Alright, and it might be Villageinvader Films.
It might be. I'm not sure.
Villageinvader. Anyway, Villageinvader or
Villageinvader Films, I'm not sure.
Good question, mate. Thanks for sending it in.
Um, oh, you're going to like this one, Steve.
BMC H says, Can I use tubeless presta valvles
in my Schrader rims?
- You see, I've got a problem.
I've always had a problem, I don't know,
between the thick ones and the thin ones,
which are which?
- And doesn't that reassure everyone?
Does anyone know? Does anyone know
the difference?
I mean, I'm sure if we go online,
we could find out. I think Schrader's the big
one. Presta's the little one, right?
That's right. Dom is nodding. Dom knows.
Thank goodness.
- Yeah, I've been on these press junkets,
people say, oh, you're a press for Schrader,
I go um, the thick one.
Yeah, that's just me.
- Yes, well, so getting to the question,
so you want to go tubeless. You've got
Presta valves, but on your, you've got
rims with big holes in them.
- Yeah.
- Now, I think you're gonna struggle
because your Presta valves are going to be
too small, but you can get uh, an adaption.
That means you could do it.
My big question.
- I knew it was coming.
- Why don't you just use Schrader valves?
You could, couldn't you?
You could.
Because that would be a lot, that would
make more sense, but you just BMC H, he's like,
no! I will not get different valves.
- What BMC H is saying is, it does actually
make sense.
- Wow. We're seeing thinking happening.
(making sound of wheels turning)
We're seeing thinking happening, right?
- Um, I kind of agree with you as well.
- You can do it. You can do it.
You can buy an adaption that means that
basically you can make that hole smaller,
and it will work, and valves are Presta
valves that will actually sit in a wider hole.
- But, BMC H, I think you should champion
the Schrader valve cause and stick to it.
- Yeah, cuz basically we all like the thick one.
We all like the thick one. It's just easy.
- Yeah, you got a car garage...sheee.
- Yeah
- You know what? You can, it's easier.
- And I think the little, thin one looks stupid.
You know, we were talking about tubes,
so let's take a quick break and take a look
at the mistakes you could make
while going tubeless.
- When you remove your valve core,
there's two extra benefits you get.
One of them is it makes it very easy
to clean, so you can get that solution
out that dries up and causes issues with it.
And the second one is you can actually
put sealant directly into the tyre
through the valve itself using a syringe.
This is far less messy than actually pouring
it into the tyre. It does mean when your tyres
are seated, if you need to top up on sealant,
you can do this easily.
- Okay, let's keep it rolling.
I'm testing Steve with these questions.
Uh, next one from Lolsteringu or
Lolsteringu. I'm getting a bit confused
on these names now. I recently bought a Haanjo
Tero. Which I think is a a diamond.
It is a rigid road/gravel bike with drop bars,
and I've taken it my local mountain bike
parks multiple times recently and enjoyed it.
I was wondering if I should stop this madness
and buy a purpose built mountain bike
or should I stop being a wimp and continue
with my drop bar bike out in the mountain bike
trails?
- Is that a ques, well, do you know what?
I ride a gravel bike. I really enjoy it.
I mean, the only problem with them is
you can take, you push them harder and harder
they buckle wheels and stuff like that.
But you know what? There's some amazing
valley mountain bikes out there.
You'd have to break the bank to get one,
so I have two bikes.
- Have two bikes. You can never have too many
bikes.
- No, no.
- Everyone, everyone in this building thinks
a lot of bikes is a good idea.
- Yeah, I don't think you need to choose.
It doesn't take away the fun on other bikes.
- No, that's true. That's true.
- Buy an ebike.
- Buy an ebike, yes, they are fun.
Yeah.
Um. I, I tell you what. I love a gravel bike.
Um, and I tell you what, you've only got to
look back, search on Google, tomac, 1990,
you are going to see a guy on drop bars
doing stuff you wouldn't believe,
going speeds you wouldn't believe.
Fair enough, he's got mountain bike wheels
on, but it just goes to show how far you can
push it with drop bars on.
- You should see what he does
on a drop bar bike.
- That doesn't count. That's cheating.
That's filming. It's different.
It's all smoke and mirrors.
- Are you telling me you were cheating?
- It's all green screen.
- You were cheating when you went over
that bridge in Bristol?
- Last year, I really did. I've got a stunt man
to do that.
I'm not doing that.
It's crazy.
- Well, even the stunt man, he actually did it.
- Yeah, I didn't do it.
That's dangerous.
Rowan Connolly says, Got a brand new hardtail
for 600 quid. Uh, good for you.
And I really want to upgrade it
as the frame is super good and strong,
but the rest less so. Worth it or not?
Worth upgrading a 600 pound bike?
- I'd say it's always good upgrading an
antique. Sorry.
I think there's some great full suspension bikes
out there.
- Yes.
- For, you know, for less than a 1,000 pounds
if you need to. Why get (beeping) hardtail?
Just, honestly, there's some great stuff
out there now. Just move on.
- I'm disagreeing. I'm disagreeing.
You're getting both, both angles here.
I think, dear, I think a good hartail's
wicked fun, and if you love the frame,
man, give it some love.
- Yeah, if you ride in smooth, single truck
mind, but if you're riding proper off road,
you need some full suspension.
- You can't say you don't get both angles
from GMBN. There you go.
Pick, pick between them.
- Adam Segerlund says, I'm gonna buy a bike
in the three K range, should I go for an
al-aluminum frame with good components
or a carbon fibre frame with cheaper components?
I almost, now, look.
Now, before you say anything, see
- I better go.
- I'm going to say I like, I like
- Well, man, it's been real.
- We want to hear your answer.
- Oh, God.
- I think a good al-aluminum frame, um,
I like them. I like them.
And, um, I would personally go for,
for the reasons that I like an al-aluminum
frame I don't see a problem with them,
and good components is what I'd be turned on
by. Steve's probably going to say
the same, but for different reasons.
- Should I just not answer the question?
- No, I want to hear your answer.
- Okay, look, basically, it does not matter
on the material, whether it be steel, al-aluminum
or carbon fibre or plastic or is there any
difference between carbon fibre and plastic?
Same thing.
It depends on how the frame is made,
so you can get a great steel bike.
You can get super light steel bikes.
You can get great al-aluminum bikes
that are a good stiffness, flex, sorry,
a good flex stiffness balance.
You can get carbon fibre bikes that
are too stiff. I mean, I'd be looking,
I'd actually be looking at the chassis
rather than the components.
- Yes. Yeah.
- Um, so
- There's a lot there to think about,
but generalising, right? Um, I can see that
there's a bit of a point you've got here
on the carbon.
- Plastic.
Martin, it's basically like carbon fiber's
just like putting a cake together.
I mean, some people put as much effort
into putting al-aluminum bikes together
as carbon fibre bikes.
- Easily, for sure, for sure.
- Like I said, there's good carbon fibre bikes,
and bad ones. There's good al-aluminum bikes
and bad ones, so
- Right. While we're talking about carbon fibre,
let's take a look at this video Dougherty
did. He put a lot of hard work into it.
Seven things you didn't know about carbon fibre,
including it might just be plastic.
- The carbon fibre is a long strand of material
made from carbon atoms, and it's the fraction
of a size of a human hair. Thousands of these
are spun together to form a yarn,
and it's these yarns they use in the pre pregs
sheets along with resin. Carbon used
in manufacturing comes in two forms,
prefabricated tubes, or prepregnated sheets,
and it's these sheets that are commonly used
these days. What is the layup?
The layup is simply the manufacturing
process for making a frame.
They lay prepreg sheets into a mould,
often around a bladder.
- This question is from Malik Allard,
and he says, I'm always seeing people
fly around birms.
- No, he's not saying. It's bedrooms.
- Birms.
- B I R M S
- He means birms, and when I do, or when I do it,
I don't pull my brakes, but I slide out
because it doesn't look like when they do it,
they're using their brakes. Should I use
my brakes when cornering or am I doing it wrong?
I still want to keep my speed,
so he's seen some really fast riders.
- Lean it in, Malik. Lean it in.
- They don't seem to use their brakes
in the birms.
They're not.
- They're not.
- They're not unless they're trying to stop.
- They're actually a hundred percent
not using their brakes in the birms,
but, um, the thing is you look at Sam Hill,
he does't even use the birms.
- No, he doesn't use the birms or his brakes.
- No.
- Those fast guys, you only want to take notes
on what they're doing to a certain extent
because they are doing some things that are
next level. Um, you're going to get there
in due course.
- Go and try some corners with no birms,
flat, rooty, horrible corners, teach you
good skills
- Yeah, and it gets back to that point
about those ties, is learn about grip,
find where the grip is and that's where you
find your speed.
Yeah, absolutely.
To help us with that, let's take a look
at how to corner fast, which is a video
we made before.
- So flat corners are probably the hardest
corners to try and ride fast because a slide
can easily turn into a crash.
Therefore, the fundamentals are really
important first. I think back to those things
I always talk about in cornerning techniques
videos, so outside foot down, trying to get
your centre of gravity low into the outside
of the bike, angling the bike over,
looking to the exit if you can.
But no corner is the same. Here I've got a
root that runs diagonally across the trail,
probably the worst direction you can
be going in, so I might need to just do
a slight bunny hop over that,
even though I'm still looking around that
corner. So to get fast round this corner,
it's going to take confidence, commitment,
but also very good line choice.
- Right. Quick fire. Steve, are you ready?
- Yeah, I guess so.
- Here we go. Oliver Tew says, I'd rather
do big drops on a BMX so I don't knacker
my nice expensive mountain bike.
It's a statement that Steve,
what's your thoughts?
- Uh, Oliver, it doesn't matter what bike
it is, it comes down to rider skill.
- Yeah, that's absolutely true.
Black Eclipse, could I put downhill forks
on my 160 travel mountain bike?
- You can do whatever you want.
Do it how you want.
- No rules. Like it.
Um, Yash says, why is there a creepy hand
on the shelf?
I don't. There's not, is there?
I don't like creepy hands. There isn't one.
You may have misseen. It's possible.
Someone who doesn't have a name,
Is there such a thing as a bike with rear shock
but no fork travel?
(laughing)
- Can you imagine how that would handle?
I really hope there is, is my answer.
- Oh my God, someone's going to design that now.
Great idea.
- Yes, Matthew Quin.
Are alloy bike frames any good?
- We answered that earlier.
- Yeah, we did that earlier.
- Look, alloy, plastic, carbon fibre, that
same thing, wood, bamboo, same thing, right?
It depends how it's made.
- A question from Archie Hunter,
my question is for Dougherty.
Oh, this question. He's pretty tall, and I'm just
wondering where Dougherty gets his shoes from
because I'm a UK size 12, 13, which is a 456
in US sizes or something like that,
can't find the size anywhere, please help.
So, we wanted Dougherty, please answer him,
where to get big shoes like Dougherty,
but he didn't reply.
- You call him.
- Call him now.
- Call him.
(phone ringing)
- [Dougherty] Hello, mates.
- Dougherty.
How it's going?
What are you doing?
- [Dougherty] Um, I'm going to search
for the bikes, bikes.
- Well, we're trying to answer a question
on Ask, and you're live on Ask GMBN,
um, and we're trying to answer this question.
This guy Archie Hunter has got big feet like you.
Where do you get your shoes from?
- [Dougherty] Well, sure my running,
I'm running mixed two of the shoes,
I'm running north sway, so that's a shoe,
so they call for them in a moment.
So I'm using their centre grass endura
mix.
- Oh, nice.
- [Dougherty] This shoe, it doesn't really let
much water in. It's quite warm. It's quite
robust that michelin dual rubber sole on it.
It's pretty good for walking off the bike
this time of year when it's pretty horrible out.
- This is a thorough answer.
- Well, it's Dougherty. It's always
a thorough answer. Right.
Correct me if I'm wrong.
This is sent in by Daniel Christiansen.
His friend Anders Dall has been taking on
little double gem. They've got a bit
of an argument about what needs
to change about this to make it happen.
Anders is saying that the he's cased
it badly, but his opinion is that
take off and landing ought to be changed.
Daniel thinks he might need more speed.
Steve, let's take a look, um, and see,
what you think he needs in this bit of video.
My God, ooof, he only just made that.
Wow.
That was close.
Oh, it made me shudder a little bit.
Made me shudder, and it's sent Steve
into a nervous breakdown.
- Oh, God.
- What do you think about that?
Do you want to see the second attempt?
- Let's see. Before, before giving an opinion
- Before we give an opinion because second
attempt, surely, Anders would have tried
something different.
- I don't think we're talking with
soil texture or take off or landing.
- There he goes, bit of slo mo.
Oh, it's the same again. It might be worse!
It, just enough, woohooohoooo!
- Simple answer. You need to be caning it
way, way more than you are.
- Yeah, it's not to do with the take off
or landing. Um, the landing is like, whatever,
deal with that, but the take-off, you could hit
that take-off, it's long enough to hit it
at a lot more speed. You could squash it
through there. You would fly.
So, Steve, what could you throw these guys to?
- Yeah, you need to check out the video
on EMBN from 10 time world champion
Michelo Verulios, the top five ebike tips.
- Oh, nice. Greatest downhill rider of all time.
You got to ride with him. That is incredible.
- It is bonkers.
- He does look mad.
I'm going to send you to this one.
It's how to pump a manual.
Good video, that one.
Good skills, be able to use that.
Um, make sure you hit the old, load
and subscribe, and don't forget to give
us some thumbs because we like that.
See you next week.
- I won't be here.
