(energetic music)
- Welcome to the 108th "GCN Tech Show."
- This week, we've got new lightweight clothing,
new tubeless tires, the bike vault, your upgrades,
and potentially carbon-fiber bikes
that are going to be cheaper than aluminum.
- Oh, it's going to be a good one!
- It is, let's do it.
- This week's main talking point is our carbon-fiber bikes
about to become cheaper than aluminium bikes?
- Yes, this was brought to our attention by an article
on cyclists.co.uk.
Greg LeMond has a company, rather imaginatively named,
called LeMond Carbon, and they've apparently developed
a technique for manufacturing carbon fiber
that increases output at a lower cost
than traditional carbon fiber manufacturing techniques.
- And the result is of course being able to offer
a carbon fiber frame at a significantly lower cost
than an aluminum one.
We've got the laptop in because they have a quote,
and according to Composites Today:
LeMond and Deakin University are teamed to commercialize
this innovative technology which enables reductions
of 75 and 70% in capex and energy consumption
per kilo of output respectively.
- Hmm. - Makes sense, doesn't it?
- Yeah.
This doesn't appear to be just marketing hype either.
The manufacturing process has been independently verified
by an audit carried out by Bureau Veritas.
- Yeah, Composites Today again report:
The Bureau Veritas have measured total oxidation times
of sub 15 and sub 20 minutes.
I'm reading this off the paper
because it's quite complicated.
Over two separate production campaigns
of 24k standard modulus carbon fiber
achieving fiber tow properties in excess
of 270 gigapascal tensile modulus
and 3,500 mini pascal tensile strength.
Does that make any sense to you?
- Yeah, obviously, yeah.
- All right, okay.
That's all right, you're a doctor.
- Yeah.
- A look on the LeMond bike site says that the company
is looking to make carbon bikes more affordable
than ever, this after LeMond was the first winner
of the Tour de France aboard a carbon fiber bike.
The site also suggests that a few of these bikes
could possibly be released later in the year.
So stay tuned for some of those.
Yeah, it's exciting,
but it's not the only way
in which carbon could become more affordable.
So keen-eyed viewers of the "GCN Tech Show" may remember
the Taipei bike show last year, I came across
this new form of carbon fiber, a new injection-molded form.
So the idea is that you can injection-mold carbon bikes
using these carbon pellets.
It's also recyclable which is nice,
but injection molding has the potential to be
much more cost effective and much cheaper
than traditional carbon layup techniques.
- [Chris] That's all well and good, Ollie,
but what on earth is that in your hand?
- [Ollie] That's the container that holds the pellets,
the carbon pellets.
- [Chris] You sure about that
'cause it kind of looks a little bit like--
- Don't worry about that.
Anyway, let us know in the comments section down below
what you think about more affordable carbon fiber bikes.
- Time for hot tech right now,
and Mitchell in have expanded their road tire range
with a tubeless-ready and a time-trial-specific tire.
The new tubeless-ready tire,
the power road tire is said to include tubeless tech
which will seal the carcass from bead to bead
which we'd hope it might for a tubeless tire.
- [Ollie] You would, yeah.
- [Chris] Also, it comes in sizes up to 28 millimeters.
- [Ollie] Yeah, the TT one is the one
I'm most excited about. - You look excited.
- The Michelin power time trial, right,
is said to be the lowest rolling resistance
and lightest tire that Michelin has ever made,
and is available in 23 and 25 millimeters.
- Sounds good to me, Ollie.
Time for some clothing tech now,
and Castelli have launched a new
lightweight jersey and short.
- Yeah, the bib shorts are called the Superleggeras,
and they're said to weigh, right,
just a 141 grams in a size large.
That's very light, but to put it in perspective,
that's even less than the
average banana and even less than
Castelli range-topping free aero race
for bib Shores as their claim to a 172
grams in a large well
- And the climb of
3.0 Jersey is 116 grams
although weirdly that is actually 30
grams heavier than its previous
incarnation that's because they have now
got reinforced pockets slightly
different sleeves and a longer tail so
complete rethink about Jersey yeah I
mean these Jersey and shorts are
designed to be worn in extremely hot
environments and that's why
lightweight pretty cool it's just days
away until the start of the Santos Tour
Down Under and I've got to say I'm not
missing being at home one bit because
check out this weather it's absolutely
lovely about 28 degrees right now right
just to the side of me I've got the
teams and where will the mechanics hang
out and the riders and all of their
bikes and kit so it's time to get the
detectives hat on and have a look around
for some new tech see you next week
thanks John more hot tech next week now
last week we asked you to vote which
olympic track bike for the Tokyo games
is the best
- Which one would you have chosen?
- Well it doesn't matter because we asked
the viewers the choice between the Hope
Lotus the GB by the French Federation's
look the new look track bike yeah the
WRX super-mega 60,000 pound by to town
the Pinarello mass Oh which one will you
go for
- Pinarello looks amazing
- Well you're not alone the Pinarello won the
vote with 37% in the app so
- what do they win?
- well it's just official that's the
best one that's Italy that's the best
the best olympic track bike
- we'll find out in the summer wont we actually it
- doesn't matter it is
time for scream riding upgrades buy
upgrades where you submit evidence of
the upgrades that you've made to your
bikes or equipment in order to win the
ultimate prize the GCM cap it can be
anything it can be animations like 3d
renderings cave paintings we haven't had
a cave painting yet but there's still
time
- please don't submit us cave paintings
- first off though we have to
announce last week's winner it was come
on are you bringing results in so last
week we had
- we had Paul's renovated
commuter and he was up against mr. seven
four six nine seven seven mystery bridge
stone
- yes and with a whopping 74% Paul's
renovated commuter has won meaning that
mr. seven four six 977 remains anonymous
despite our best efforts to
- love his name who that was yeah Oh
this week's entrance come from AJ
Wallace AJ Wallace bought a cheap bike
from ebay to use as a winter bike
over Christmas he decided or they
decided it'd be good idea to remove the
paint from the frame give it a broth
finish a trines a paint stripper which
sounds like a lot and 12 to 15 hours of
sanding later and the frame was ready to
be clear lacquered
- that's a lot of elbow grease
Aw no paint strip only
actually says and there although greases
will set a new CONUS decals off ebay
1:05 flight day on the Wi-Fi 5 700
series 53:38 at the front or 38 nice
lies ring 32:11 at the rear get all
those it comes back in here probe Pete
LT Batson stem EC 90 carbon stem from
Easton
oh sorry calm subtle look at this that's
what it was blue yeah nice shape like
cool Kona yeah
- those wheels are quite nice
But I think this is one of my favorite one so
far more time look at that
how cool is
- that eyes black I made it
all by modern modern Kona logo isn't it
over the old one electrical yeah it's
cool is nice back to pedals on there as
well for power meter
- those served raw
eights rims they are Sayle 20 2004 or
something like that similar areas to the
reflector pros that used to have a
similar spoke pattern
- I like that
a like that a lot
- I like the fact that
it's also not cost him an absolute
fortune because it's just a reasonably
priced group set I'm all done with an
original frame
- uh it's not going to be easy
for AJ that's not a music you know why
because he's up against Alex tibay 2005
the 2005 Alex Teddy hi my name's Alex
and he says he lives in Tipton in the US
- you also said he's 14 and perhaps
that 2005 is Berthier
- it could be or there's 2005
Alex debate
I would give it up yeah
- anyway
he lives in Tipton in the US of A and
he's built this cross bike out of a
hybrid pipe that his grandpa had with
parts he got and just from bits he had
laying around he's got some new Shimano
surahs shifters good choice new vitória
33-millimeter tires new Tetro brakes new
bar tape check it out you also have a
new put a different saddle on it in a
seat post and just great when you've got
bits lying around you need up cycles
- a metal cage I wonder if you watch my
video about thing cages
- he must have done my stuff mother
- in the house today otherwise
yeah neither would I just could job he did that
yes there is the original hybrid bike
that's and look at that that's
transferred in or transformed into a
cross machine
- with an era C post yeah
that's cool isn't it
- that's really cool
it looks like a big bike see you must be
a tool boy
- yeah like he's chain ring these got on
there as well
- I think that's make a job
- price but it's wicked isn't it
- no it's worse to me Rosa no but for a 14-4 like
- for 14 years old weld I couldnt of sone that when
I was 14
- completely repurposed the bike
yeah right come on we want to know what
are your choices vote in the top right
hand corner your screen right now
it's now time for the bike vault where
you submit pictures of your bikes and we
judge them to be either nice or super
nice and if they're super nice we ring
the bell they may go in the vault
- have you got the Bell she's just over there I
mean normally I ring the bell but
Johnson so happy
- I'll ring the bell
So happy
- so first up this week trying to get into
the vault uploaded from the gcn app is
this from cycling scenes don't think
that's his real name but he's in
Scotland I cook apparently he or she we
don't know so it could be his real name
is that what you're saying no actually
it's nice like if I've got it on his top
tube let's zoom in how do you see a
minute how do you see just like a pinch
and zoom surely do that
pinch and zoom just just look you do it
here they go
- he's only a few years older
but technology clearly
- what's that say
- too many pixels or not enough mix of
Masterman his name is madwoman Aaron
summoner Owen Owen do you know his
- name's Masterman cut
- no we leave an item is brilliant
- that's good detective work isn't it well
- darling may be your pastime as a doctor
has been wasted after all
- anyway what
are you thinking about that Chris
- I like
it how about the way the wheels are the
colours geared a nice position on the
bike
- make gold chain
- gold chain is yeah
- he's lined everything up correctly got
biggie smalls going on there
- how do you know what music is Linden
- that's the chain ring combo biggie
smalls
- right that makes more sense because I
never really understood what that was
all about
- yeah I think that's it I think
it's really nice
I almost a super nice
(bell ringing)
- Do you think that's enough?
- Yeah lucky that made it into the
vault with that definitely next up we
- have user Collier seven four seven four
which I don't think is your real name
either uk-based cyclist with his ribble
endurance SLR no elaborate pitches and
beauitful places just a picture up
against a fence but it's pretty cool
- you can clearly see all the details you can
- and black-on-black actually works on
this one
- that's a nice-looking bike but
and he's he's been watching the video of
how to get in the bike vault we've got
biggie smalls he's removed accessories
and appendages we've got no air hang on
- hang on
- that saddle looks like an
appendage on its own look at it we have
the funny shape Southwell saddle is it
does this in the description I'm not
sure but but he's lined up his wheels
he's very clean
there's a nice one
- super nice okay yeah
go on feel generous
(bell ringing)
Sally Italia saddle by the way
- yes
- oh this one I like look at that
- Yes
Niklas grow one the first Nkilas grow on the app
he has uploaded his Bianchi look at that this
is a little Monroy cut the color-coding
yeah uses it in the Tuscan hills to ride
you know the Strada Bianchi road engine
- our qualities
- yes or 209 that's what do
you what do you think of that I think
- I think its stunning it looks lovely is
tasteful nice shape it's quite a big bike
- I'm a big fan of the red saddle and Volta
- yes
- stickers
- Yes
- it's white and red is it's
nice isn't
- its very classy
yeah and those straps yeah I really like
that
- and how neat is that little frame
bagged another bar bracket there
- yeah
- well that's easily first on their
- sandwiches definitely marmalade
sandwiches
- yeah like the challenge tires
as well and and Biggie Smalls just about
- come on come on go on there three in a
(bell ringing)
three in a row
- bloody hell anyway right next up we've
got Ivan Farnsworth
- John is going to be
gutted that he's not here because he
loves a derosa
- he does Ivan Farnsworth well done cement it
through the gcn app bonus points for
that he's just purchased the this SK
vision met Ron handlebar like you've got
that on your or bear same but
- I do have
exactly that buy it so it's a good I'll
take a group set and hunt wheels they
look like Victoria's hires why I'm
actually good don't yeah they are fitori
cross ties and then the second guess
yourself yeah that looks stunning
- it's very up gold chain yes I'm not sure
- I'm not sure about the exhaling but that's really
nice tell you what though so it's
annoying me those bottle cages different
colour yeah but look that matches the red
in the DeRosa logo and on the Danube and
so maybe it's put more thought into it than you think
yeah maybe yeah
a lot of fun it's got disks as well feel like
that's really cool
biggie smalls as well yeah, no access
- come on let me ring the bell Olli
- go on then
(bell ringing)
I'm so happy right now
- right
- oh just gets better and better this week
- oh look at that look
- I'm not sure which bikes been
submitted here but I'm guessing it's not
the triumph in the background which is
actually a modern take on a retro classic
as far as I can tell
- is that a Bonneville in the background
- cool though the fact they're both
British racing green effectively as
close too
- that's pretty cool isn't it
do you reckon you could escape escape
- jump over a fence
- propagate the Nazis
into Switzerland on that barn
- no not me
- I don't think
- I might be I have to either
- You know the only issue I've got here
problem if we don't know which part
we're looking at
- I think
show on E but it's hardly guess that it
is the wrap
- but its hard to see the
rally because it's the background so
putted and one of the things we say nice
clean background essential
- okay well I happen to know
happen to know there's more than one of
these pictures and one of them was with
that across the background but I kind of
liked this one and since I chose this at
one this week hence all the supervisors
um you know what I really like about
this bike Holly a lot of the putti is
the fact that it's 50 or so at the rack
on it
- yeah its got the rack on it
- Yeah its quite a good rack
the fact that its 50 years old ad still
functioning
- Yeah.
- oh you know what you've just
picked really nice ones this week
- I just
found a generous loving giving mood come
on come on go on there that's it I'm
- Yay!
(bell ringing)
thats it im going to put the bell away
- Okay
unfortunately that's it for this week's
show I hope you've enjoyed it if you
have them please give it a thumbs up and
if you'd like to support the channel
well that's easy all you need to do is
subscribe if you haven't already and
click the bell icon
- you could also head over to the shop and
check out some of our GCN clothing as I
can you
- Oh yeah you could and if you'd
like to watch another video or fitting
bottle cages and click on Chris
- Its worth
worth and hes worth the watch
- And his majestic beard
