Hey everyone and welcome back to another Tuesday tip
So recently I uploaded a video where I was riding my bike on a snow-covered skate park and on this video
I received a comment from user BSD 12 that says hey Brant
I was wondering if riding in cold weather like 50 degrees will actually make your bike weaker or
More easy to break because of the cold metal. Hope you reply. I think we're doing a little bit better than just replying here
We're making a video out of it
So I feel like I kind of get the gist of the answer to this question, but I don't know enough
Scientifically to explain it in a articulate way
but I do have a friend named Patrick Kelly who is a BMX rider as well as a science teacher and someone who makes
Educational videos here on YouTube which I'll link his channel in the description below
so I sent him the question and he has an answer for you guys and he put it in the form of the video that
We're about to show right now answering the question of whether or not cold weather makes your bike weaker also
Stay tuned to the end of the video because I have a park tool
Christmas New Year's giveaway that I'm going to be announcing and talking about at the very end of this video
So here's Patrick answering your question
Alright this phenomenon isn't as weird as you might think
Because you've actually seen it all the time when it's been like a hot day and your to blows up
You've seen that kind of same thing happen, but it's a little bit different when it comes to metals. Let me explain so
I'm assuming that you
dear viewer
Probably ride bike so you probably know that most bike companies will heat treat their parts for strength and there are a bunch of different
Types of heat treating different recipes for different metals different things that you're trying to do with it
But they all have the same purpose
Make your bike parts less likely to break and that makes sense when you're throwing iron into a fire
That's like over 1,600 degrees Fahrenheit. But what about for the day-to-day stuff?
Like what if you're someone like Brant who has freezing cold temperatures in the winter?
but over 100 degree temperatures in the summer all metals deal with this thing called thermal expansion this phenomenon where they'll
Expand in hot temperatures but contract a little bit during cold temperatures to understand what?
We have to think really small like molecular level small while our eyeballs see a solid structure
even metals have tiny spaces between their molecules and each of them are vibrating super quickly as
Temperature increases their vibrations speed up and they start to spread apart
Same number of molecules as before but greater volume if you work in construction or plumbing
Then you're already super familiar with this. You got to make sure that components like pipes won't shrink in the winter time
I'm trying really hard not to make an immature joke about that right now. So all of those molecular
rearrangements and movements mean that your frame can actually snap a little bit easier in the winter when engineers design
anything they need to make sure to choose a material that will balance brittleness the ability to snap easily and
ductility
the ability to bend or deform but not break entirely the colder it gets the more brittle your metal the warmer the more ductile your
Metal and yes, this is the nerdy craft that explains all that
well
All of that make a big difference for your summer time versus your winter time riding
Sort of obviously other things like what sort of metal it is
How old the part is how much stress you're placing on it are all gonna factor into the when does this part actually?
break and all this is still just talking about temperature big fast changes in temperature are also gonna lead to things like
Condensation making your bike wet and leading to all kinds of long-term structural problems
Like think about taking your bike off the bike rack and wheeling it into your room
That's a potentially big difference in temperature in just a few seconds. So final message here
Yes, technically cold weather does make your bike parts more brittle
but it would have to be really cold to snap something big and structural like a frame or four at the very coldest temperatures that
Most of us would go out in you're probably just looking at a couple more broken spokes than usual
So there you have it the answer to whether or not cold weather can make your bike weaker
this is something that I've personally wondered about for years now being someone that lives in Ohio and has to ride sometimes in 30 and
40 degree weather and I think Patrick did a fantastic job explaining everything in a very thorough way. So if you guys enjoyed
Patrick's portion of the video or you learned something from him do me a favor and check his channel out in the description below there
Will be a link to his channel
But now let's get into the park tool Christmas New Year's giveaway that I mentioned earlier on in the video
with the help of Park Tool
We will be giving away a BMX
specific tool package and this giveaway is going to start today on Christmas Day and
Span into January first New Year's Day. That's when I'm going to announce the winner
and in this giveaway, the prize will be a
PA
W66 inch adjustable wrench and then a petal wrench similar to this one. Not this exact wrench
We're giving away the PA w5 then we've got the 8 WS 10
Which opened up here it's got everything on it from one point five to six millimeter allen wrenches
then finally we've got the
Mq-1
This is how I take off and put on all of my wheels and on it
we've got a 15 a 17 and a 19 millimeter socket drive as well as a
3/8 socket wrench Drive right here, and we will be also giving away a eight millimeter socket
Allen wrench so with all of these tools you should be able to take apart and put together and fix
most things on a BMX life and with that being said all you have to do to have a chance in this giveaway is
Go to the link in the description below to this Instagram post
Which will be up by the time this video is up
And all you got to do is follow the instructions in the caption of that Instagram post
I'm probably going to have some sort of question that you need to answer
But ultimately it's going to be just leaving a comment and making sure that you follow both myself and park tool over on
Instagram and I suppose I should set some ground rules so that
Everyone has a fair shot in this giveaway, and my rule is going to be very simple
You can leave as many comments as you want
But when I go to pick a winner if there is more than one comment in a row from the winning person
I'm going to pick a new winner
You can leave as many comments as you want
But not more than one in a row or one at a time with that the way that we're going to be selecting a winner
For this is that on January 1st and New Year's Day at 12 p.m. Eastern Standard Time
I'm going to take a look at the post and see how many total
Comments, there are I'm gonna take that number and put it into a random number generator and then whatever number it comes back with
I'm gonna count down from the top and whichever comment I land on with the number that we're given is
the person who wins the park tool BMX specific tool package New Year's Christmas Extravaganza
craziness Brandt more YouTube channel prize
So with that I'm going to try to have that Instagram post up
today before this video goes live and that's going to be the only
Place that you can enter to be considered for this giveaway. So you have from now
Until January 1st New Year's Day at 12:00 p.m
Eastern Standard Time to get over and get your comments in as well as follow both myself and
Park tool on Instagram and I am going to be checking. So if you're not I'm going to pick a new winner
So make sure that you get over there get your comments and and do everything necessary
so you have a chance at winning the BMX Pacific prize package from
Park Tool and with all of that being said I want to give a huge shout out and thank you to Patrick Kelley for once
again
Contributing his time and knowledge to one of my tip Tuesday videos. He does have the YouTube channel
Like I said, it doesn't have anything to do with BMX, but it's all educational and it's all very well done
so like I said about
7,000 other times in this video get on over there and check it out
I want to give another
huge shout out and thank you to Park Tool for always supporting me as well as giving me the
