I made a video a couple of days ago about riding double disc wheels which is what I'm riding now
I'm heading back to the studio to um take this front one off because I need some of the parts
for a future video but the first thing I wanted to address in today's episode is that I was wrong
this wheel is a hundred percent UCI legal all disc wheels are apparently these are only banned in CTT
events which is cycling time trials we have an organization in the UK called CTT that govern
all of the time trials in the UK and uh you're not allowed to ride disc wheels in their TTS
or Discworld covers like this but the UCI despite what I said last episode allow them evidently not
many people know about this rule because nobody pointed it out in the comments that I was wrong
but I did get a message from some Aero experts Xavier from errorcoach sent me a message saying
double disc vid you know they're fully UCI legal they're actually fine to ride better the faster
you go as the effective your angle decreases CTT state that you have the have 45 percent
of the wheel still exposed or open as they put it the UCI have no wheel regulations for timed
Road events they have an approved wheel list but that's for Mass start Road events and cycle across
Etc there are no try spokes track 5 spokes disc wheels Etc on there which is something
people continually get wrong if that's not enough proof for you here's uh some pictures
of Shara gillow actually using double disc wheels at the 2012 London Olympic
TT shouldn't win but it looks pretty cool and she didn't crash maybe I'll have to put this
back on after taking it off and test it again at higher speeds maybe even in an event if we
can find an event where it's actually legal just to see how much more stable it is at high speed
if what Xavier is saying is true and the your angle reduces at high speed and maybe they're
ridable and you'll start seeing more people use them in UCI events a little birdie tells me that
a few World Tour teams might have some disc wheels some front ones but I can't tell you who
another person who messaged me was Alex dauset who uh aside from pushing Lawrence Carpenter off
his bike oh God he's also quite well known for doing well in bike races and is an aero expert
or nerd which word would you use here's his take on the front disc wheel hello welcome to
francis's channel now I've been here before I've been here more famously known on this
channel for pushing over Lawrence think of a disc wheel like a sail now a little bit of
your now you're really confuses people that don't speak English is their mother tongue
because you've got your as in it's yours you got you are you're and now we've got your as
in your angle uh zero your angle almost doesn't exist it's when it's Arrow straight normally on
a velodrome banking you're looking at one or two degrees of your out on the road you can
experience every anything up to well anything really depending on the strength now a front
disc the big problem with them is handling as Francis said but there is speed to be gained
and it's it's very tough to put a this is X percent or X Watts or X time faster because
it really does depend on the conditions there is going to be a game the more your you swing around
to but there's going to be a stall angle stall angle is where everything just goes to
swear everything goes wrong stall angle with the front disc that's the point that you fall
off if it's too strong or Too Much from the side that's the point where you're seeing
no aerodynamic gain and a significant loss in time through being stopped and on the floor but
up until that point what you effectively have is an extra sale on your bike and so you can
develop thrust but it's doable and I think at some point someone's going to have the
cojones to actually try it again I think the trade-off to it as we saw from France's video
is number one stability like are you actually just simply riding further trying to handle
the bike and TT bike you're on Tri bars like Francis was it's a bit of a cop out really
riding on his road bike I've found if something is difficult to handle my bike then my position
fails my shoulders come out my body comes up because I'm trying to wrestle the bike and
then any benefits that you might get from the front disc are outweighed by the just general
panic because panic and being closer to certain death has never conducive to fast time traveling
in conclusion it's probably another 30 seconds over 25 miles lots of you may have seen that
he's actually taken a step back and retiring from Professional Road cycling which means well I hope
he's going to be uploading on his YouTube channel a lot more so if you would like to uh follow him
or subscribe to him he he produces very good videos all about cycling then do it'll be in
the description down below part two of today's video inside of here there are some sunglasses
foreign
on this channel is what sunglasses are you wearing
consider this section of the video sponsored by Sun God
Sun God have been a supporter of this channel for the last two years and I actually went to
visit them a lot of you will have seen those videos where we went mountain biking in verbia
and it was very very lovely We are continuing our partnership and I wanted to take this quick
opportunity to explain what they make what they do and a rundown of some of their products these
are the errors so the big thing with Sun God is that every single pair is custom if you go on
the website there are a few set options to start with and then if you hit customize you can change
the colors of pretty much everything change the lens change the little icons on the side change
the ear socks and you can make a completely personal pair of glasses I tend to go with
the errors which is my favorite model there's four different models in the pace series which
are the ones for sports the errors have no piece on the top so when you've got your head down and
you're doing an effort you can still all look forwards and you've got full range of vision
you can then choose whether you have a small nose piece or the full jaw loads of different
color options but the lens that I like at the moment is the iris HV blue HV high visibility
those are the ones I was wearing this morning when I was riding in uh but they're the iris
versions so they change brightness based on the conditions so if it's really sunny they
go a bit darker if you're indoors they go lighter they do that in a smoky one as well if you don't
want the sort of Larry yellow look but you know there's cycling glasses so they should be Larry
delivery is Mega fast in the UK they've always delivered mine next day after hitting submit
two or three days if you're in Mainland Europe and three to four days worldwide if you can't
choose between having a normal nose piece or the bottom jaw then you can um add them on as extras
when you buy one pair of glasses which is nice they have lenses made out of fancy stuff these
are called 8ko 8K Optics which are made out of two millimeter thick nylon triple layer scratch
resistant with 100 UV and impact protection and to finish Sun God had now officially reached B
Corp status which means they look after their staff they do good stuff for sustainability and
charitable causes so if you're in the market for sunglasses please consider sun god they've been
supporting my channel and my work for a long time now and they're lovely people they also look cool
and for a future episode right now I won't reveal too much but I'm letting my watch
decide my workout I'm seeing if I can follow today's plan which is base 155 Watts average
study the whole way uh I'm gonna see if I can execute this on my route home might be
quite tricky because my route home is very Wiggly lots of barriers and very uphill my
watch is beeping at me already it's probably not going to be a very good training session this
