Welcome to Ask GMBN th... (lips smack)
Welcome to Ask GMBN this week
where we have got the whole crew.
- Everyone's in. - Oh yeah.
- We're splendid. And we're multicoloured.
We've got everything.
All the information GMBN has got to offer
for you in answering your questions.
Doddy, how have we found those questions?
- We get them if you send them in
to ask@gmbn.com or if you comment below.
- And of course you can use the hashtag #askgmbn.
We have got lots of great questions this week.
Let's get straight into it.
I'm gonna test you guys.
First one, I'm a bit, I'm not sure about this question.
Leo Graham, "Can you manually unicycle?"
I'm not really sure.
- But you're peddling so you're not manually...
- I think we'll getting trolled here.
People are talking about fixies.
- Right. - They're pulling our leg.
- Wrong channel. - We're being hadded, but,
I think Leo, this question has backfired on you
if you are trolling us on what you can and can't manual,
cause Doddy right here can do it.
It can be done.
- Technically yeah, cause you're on one wheel,
and if you're not peddling, you can.
If you fit a free wheel on one, which you can do.
- Yeah, but can you actually not peddle
and make a unicycle go along?
- Well once you're going along, you can, yeah.
- How can you use a unicycle with a free wheel,
how do you know which side to get on it?
Which ways forward and which ways back?
- Oh yeah, does it saddle? - Check the saddle?
(laughter)
I've got to see Chris Holme put his feet up on the crown,
and the pedal's like, (vocalised spinning).
- Imagine catching them, no, anyway, wrong channel.
- So potentially you can manually unicycle, we think.
And we would love to see some video of you trying.
That's what we'd like.
Red Panda says "Why don't you see
any plus sized downhill bikes?"
Now this is an interesting question.
He thinks it's got extra grip, extra momentum.
He can't see a reason why not.
- Extra weight.
- Extra punches.
- Oh.
- Both of those.
- Okay, but--
- Why extra punctures, yeah?
- Well they're not thick enough.
The side walls on a plus tyre are relatively thin
to keep the weight down, and if you made them thick enough,
it'd be a big heavy tyre and
there's an argument for something in the middle.
I think we might see a two point six
or a proper two point five where it is not quite plus.
- And where would we consider a plus tyre?
What size is that?
Two point eight? - Two point eight upwards.
- Two point eight upwards,
so probably not that big, but somewhere--
- It was three inch to start with but industry kinda settled
on two point eight cause it handled a bit better.
- What is it called?
It's called a midfat so they have to be super bit fat.
- I think we've ended up at a maybe there.
That's what I think we got to is that
maybe we're gonna get bigger tyres in downhill.
Bodhi Byronboy says, "I am 143 cm tall
and I am looking for a new bike.
What tyre size should I get and is Norco a good brand?"
Now I think by "what tyre size?", we think he's asking what
- Wheel size. - Yeah.
- I think so.
One, that's relatively short now, I suppose.
Although, people says 29s are for taller riders,
I'm not totally convinced.
I'm average height, I'm what?
About five ten.
- Did you say average? Slightly below.
- Exactly average.
29 is fine for me but...
- Yeah, the only limitation is how small the frame can be.
- I mean I've seen some of the XE women races, a World Cup,
riding 29s and some of those girls are really really small.
- Quite tiny, yeah. - Yeah, really small.
- Yeah it looks like they sit
in the bike rather than up on it.
- Yeah.
You could go for a 29, but what would you recommend?
I would say 27.5 to most people at the moment.
Is that about right?
- I would say 29 to most people
- Would ya? - But look at the size of ya.
- I'm loving 29 at the moment.
- Oh, there's a conflict.
- There's no right or wrong though.
Both wheel sizes work really well
for whatever you're gonna do.
- There's no right or wrong, but I was right.
Okay next question, Odhran Ryan says,
"Air keeps coming out my rear suspension. How can I fix it?
Or do I have to buy a new one?"
- Sounds like he's blown a seal.
- Oh no, is that it? - Send it off.
- Done? - Nah.
- Service, pretty much. - Get a service.
- Submit to higher level shock.
If it's a cheaper bike, with cheap shock on it,
you might find blowing it is the end of it.
and you might be better off upgrading your shock.
- Right, right.
Okay, well so, might need a tune, possibly need a new one,
but more on the subject of shocks,
let's take a look at our video
where we delved into how to tune a real shock.
- The air shock is the most common form of shock
seen on the average mountain bike these days.
The reason for that is it's lightweight
and it's easily adjustable for a whole wide range of riders.
In addition to that, you tend to have
two damping adjustments, rebound and compression.
So we're gonna demonstrate with a couple of Fox shocks
and a Rock Shock shock that are quite common these days,
and show you how to adjust your air pull-in.
- Welcome back. Next question, Martyn.
- Right, next question is from Kumud Nakarmi and he says,
"WD40, what does it do?
How do I properly use it?
And can I use it to clean chains?"
That's a good question because lots of people are
not necessarily using WD40 for the right thing
because it's actually an amazing product,
but it's very specific.
- Let's start with the name. WD40 is water displacer 40,
so it took 40 goes to get the formula correct.
- Yes. - It's
whole purpose, it was designed solely just
to drive out water and provide basic lubrication
to stop things corroding. - Basic lubrication.
- I use it a lot.
For, after I wash my bike, chains still wet there,
I always spray it down with that.
Then get a rag and clean it off, and then rewrap.
- But...
They do do de-greaser.
- Yeah, they got dedicated bike range now,
so although you can lubricate and clean with WD40,
it's sole purpose isn't to lubricate or to clean.
- Right. - So you can
get more specific products for that.
- Let me get it straight.
If you're gonna clean your chain,
at what point would you use WD40?
You've cleaned your chain off, then you WD40.
- To drive out any water that's set up.
- And then you would grease your chain?
- Well then I would-- - Lube it.
- Dry it then lube it. - Lube your chain.
- It's part of the process.
It's not the final part of the process.
- It's a multi-use product.
- Yeah, multi-use.
John Galvan says, "When you said that the shock will
blow up," this is referring to a question we had last week,
"What do you mean by "blow up"?"
I guess maybe John's thinking,
am I supposed to think it's about to go boom?
- I'm always worried about that, as well.
- Yeah, I mean, do they go--
- Blowing a shock. - But when you say,
"blow up", do they explode?
- There has been a few cases of that.
- Oh. - For real.
- Generally meaning you're blowing your seals out.
- But it wouldn't necessarily be fire and devastation?
- Hot oil. - It'd be a miracle
if you get fire out of one of those.
I mean (laughter).
- Back in 1998, I had a Fox Vanilla?
Was it Fox Vanilla? - Yeah, really?
- On a Kona Manomano and it had blown,
and there's oil coming out of it, so I had it,
I don't know why, in my bedroom,
I was fiddling with it and it exploded
and it filled my room with oil.
There was a shadow of me on the wall.
(laughter)
- That's great.
- Well, John, I hate to say it can happen.
- Well, I've not done in a long time.
- It sounds rare. It sounds rare.
I wouldn't worry too much.
But usually, I guess, just for safety,
most shocks, if they've go--
- All shocks have oil within them.
- Yeah, generally.
It can be quiet a delicate situation.
MyKeyboardIsBroken is, he's asking,
"Guys, how to calculate the speed to jump over a gap?"
For example, if he's got a one to two metre gap,
how does he calculate the perfect landing and speed?
That's a very--
- Simple equation for this, Martyn.
It's mass times velocity divided by gap.
(laughter) I think.
- Is that right? - No.
(laughter)
- He had me there.
I was like, wow, I had no idea.
- That was quite good actually.
- After all this time, I could've
just been working it out on my computer.
- It's completely experience.
- Yeah, it's experience.
You gotta just work your way up.
- You're the gap man, Blake.
- Yeah, you gotta work your way up.
Start off small and then you know
exactly how fast you have to go to hit three feet.
Then you know after that, go a little bit faster.
Hit four feet. - Yeah.
- Then you go a little higher.
Just getting comfortable with going.
- And, of course, every take off makes a
huge difference to the gap that you're trying to jump.
- As well as if it's wet, is it dry?
If it's hard pack?
- There's no easy answer, I'm afraid.
You just gotta get out there and ride,
and you start to understand the different speeds required
and techniques, and that's what it's all about.
That's actually riding.
That's the fun bit.
- You might have a few faceplants on the way.
- There'll be some fails, for sure.
- Yes, but Blake's given us some great advice there,
so let's jump to his video on how to build a,
if you're a beginner, a mountain bike dirt jump,
and get started on hitting those takeoffs.
- Whoa, wow.
Man, this location is sick.
The dirt is perfect for digging in.
Today is the day where I show you
how to build a progressive jump, one that you can
progress on, and just get all your skills up together.
But first, you need one of these.
The spade.
- We are flying through this week's show.
So many good questions.
Here's another one from Peter Hartman.
"Great show." Last week, thanks, Peter.
Can you guys discuss what you think about
the bike industry will look like in ten years time.
Will direct to consumer brands change the playing field
of things and will that change the price of bikes,
because lower cost of entry and things like that?
Whatcha think, guys?
What's mountain biking gonna look like in ten years?
- Direct to consumer's been around for a while.
Hasn't it?
I don't know. - Yeah, it's been a while now.
Is it changing the landscape of the industry, though?
Is it making much more--
- In short term I think it is.
But I think it will always return to having
independent bike dealers and stuff
because as bikes get more complicated,
you're gonna need that face-to-face, you know?
If you're getting with e-bikes and stuff, tuning and--
- Just by saying that, e-bikes are the
big question mark of the moment.
And that will definitely change the dealer,
just like you were just saying.
- I think e-bikes for me are the thing that's gonna
really change the landscape of mountain biking, because
when people ride those bikes, they get excited by em.
That's gonna get bigger and bigger.
That is gonna change things.
But you can't underestimate the value
of an independent dealer to talk to.
- Local bikes shops. - Your local bike shop.
- Local bike shops, you can't get rid of them.
Can't get rid of them.
- Big part of riding for me. - Support them.
- Hanging out at shop, chatting about riding and
that sorta feel is what mountain bike means to me.
So I hope we don't lose that.
Lyman says, well, more of a suggestion than a question,
"Global Trials Network?" Anyone?
Anyone?
Another suggestion, a trials week, on GMBN.
I love this guy.
Parker Lyman, everything there sounds right to me.
- There could be some good guests.
- Could be some, yeah. - Yeah.
- I mean, come on, trials has brought
some great legends to the sport.
(clears throat) - I like a bit of trials.
- Hans Rey. - Hans Rey.
- Libor Karas. - Libor Karas.
And? Chris Ackerman.
- Martin Hawes. - Martin Hawes, yeah yeah.
- Danny Mac. - Enough of this.
I'll tell you what, why don't we,
while we're talking about trials,
throw to a moment in Whistler where Blake and Doddy had a
bit of a trials-off and I got to be very entertained.
- Welcome to my Whistler Trials Challenge.
(laughter)
- [Blake] It's heavy.
- [Doddy] I wouldn't go that way, Blake.
- It's close!
Okay, it's the quickfire section.
It is gonna be fast.
We're doing a clockwise direction.
One question, one answerer.
Guys, are you ready?
- Ready. - No.
- Sure, right, here we go.
First question is to Blake.
Tom Scholfield asks, "How long does it take
Doddy to do his hair before the show?"
- One hour. - An hour.
Neil, Sam Luff says, "Why is Martyn
holding a tyre lever the whole time?"
- Cause he's a fidget.
- I'm a fidget. - Haha, he's a fidget.
- Doddy, Tobias Lawson-Dick says,
"Doddy is very clever, isn't he.
First question, so much knowledge."
- Thanks.
- This one's for me.
Wez Lee, "Doddy is a guru on MTB information,
his insight and tips are spot on.
You're a national treasure to the nation of MTB DIYs.
That is all true. - That is true.
- No, you're doing well in quickfire this round.
Next one is to Blake.
Pierre Holt says, "Are Fox suspension
and Fox Protection and Apparel
from the same company or are they separate?"
- Separate.
- But are they from the same company?
- Not the same company. - Doddy knows history.
- Let's go to Doddy for this one.
- There's two brothers, Jeff and Bob basically,
and they started the company and
then they split into Head and Tail.
- Ooh, they split. - Well.
- One for clothing, one for suspension components.
- I didn't know, wow.
- This is quickfire, stop talking.
Right, Neil, Salamander Workshop says,
"I have to disagree with you guys,
I think 26 will come back to Enduro."
- You are kidding me.
- Dimensions of Earth says, a standup wheelie
can also be called a catwalk, Doddy.
- What?
- Oh, can it now?
- He didn't know that. - I didn't know that.
Thank you. - And that
is the end of quickfire until next week.
Correct Me If I'm Wrong this week is gonna start
with correcting us when we were wrong.
This is Correct Me and Doddy from last week's.
- There'll be a lot of these.
- Marlon Profe says, this is about
whether you could manual a fixie or not,
and he's saying, you could just stand on the chainstays,
and therefore, you would be manualing a fixie.
- You could, I guess. - It's a fair point.
Okay, next up in Correct Me If I'm Wrong, these videos.
First one is from Michael Hawke.
It's of his eight year old nephew,
Jasper Martin, in California.
You guys.
- You're gonna love this. - Whoa.
- Is he gonna take over our jobs?
- He's cool already.
What can he do to correct this?
- A little youth. - He's going for it.
It's all in slow mo because you wanna build the tension.
- [Blake] Whoa, he's going for the big side.
- [Martyn] I think if you can see it's going wrong.
- Oh. - Okay.
- [Neil] Ooh, is he gonna stay on?
He stayed on. - Oh, he stayed on.
- Wait. - Oh, hang on.
(room groans and hisses)
- [Martyn] It's gonna be a big crash.
- [Doddy] Oh, a tank slapper.
- [Neil] Aw, his ankle.
Wow, that's a big crash, Jasper.
That is a big crash. - Wow, that's a big crash.
(grunt)
That little guy got around that bike.
- I'll tell you what that was.
Was very entertaining.
- It was. - That's a buckaroo.
- It was an amazing, amazing crash.
- I hope he's alright. - That was a big jump.
I would say on a small bike like that,
maybe back it down a little bit to a smaller jump,
and learn how to get a bit more high.
- Yeah.
But I mean, you were committed.
- Oh yeah. - You went for that.
That's what jumps require.
Hopefully you didn't get any injuries there,
but you came down hard on that ankle.
That was nasty.
If you got away with it, you did quite
a lot of things right because it's not easy.
- Tuck and roll. - That's
not an easy crash to get away with.
- You tucked and rolled. - That was nasty.
Great stuff.
Thanks for watching us this week.
We really love getting your questions, so make sure
you shove them in the comments section down below.
You can send them to us on social media, #askgmbn,
or on our email, which is ask@gmbn.com.
Doddy, can you think of one single video we've done
that would just be great for these guys to do now?
- I can, I'll help here.
Click over here for how to night ride.
I think he wants to put something over there.
- Over here, on five basic tricks to learn
on a dirt jump bike, or any bike out there.
- That's great action to watch there.
And if you want to subscribe, then hit the GMBN logo.
