Slack Randoms: Tour de France Knives, Omni-Wheels, 272km/h on a Bike & More

by Ed Spratt  
We use Slack as our workplace communication tool at Pinkbike and we have a #randoms channel which we use to share an assortment of videos and stories from all corners of the cycling world and beyond... We thought a couple of the moments from the past week were too good not to share with a wider audience, so here are some of the highlights.

Tour de France Limited Edition Knives


The Tour de France has plenty of merchandise tie-ins but knives definitely wouldn't be at the sharp end of our list for the biggest cycling event of the year.

French brand Opinel has made a big point about celebrating the 2022 Tour de France with the release of some folding knives. Opinel's slice of Tour de France memorabilia comes in two options with the $55 'Les Maillots' design and a cheaper 'Landmarks' knife for $29.


Omni-Wheel Bikes

bigquotesLast time I built a giant omni-wheel. An omni-wheel can move in multiple directions because it has lots of smaller wheels around its circumference, so it can roll like a normal wheel, or slide sideways.

Normally you’d use at least three omni-wheels on a vehicle so that you can move or rotate in any direction. But in this video I’m going to put my giant omni-wheel on the front of a bicycle, and with some clever electronics I’m going to control the wheel so I can ride it.

I’m using the back end of the bike from the Makers Secret Santa Christmas video which Colin Furze left on my driveway. I’ll need to modify the bike so I checked it wasn’t Colin’s bike from his childhood or anything and he said it sounds cool.

As I mentioned last time, the wheel is going to be mounted the wrong way around on the front of the bike so the two wheels make a T-shape. So first of all I need to make some modifications to the front forks of the bike.

 The fact that people throw this much plastic into nature is obscene. Canada also ships its garbage to 3rd world countries for them to toss it into the ocean. ie Trudeau vs Philippines garbage fiasco.

 @hamncheez Fact is there isn't a solution. I read a statistic that 8 million pieces of plastic go into the world's oceans every day. It's been known for years that we're eating and drinking it, we're also now breathing it.
If we stopped new production of all plastic tomorrow (which will obviously never happen), there's still all the plastic that currently exists. It doesn't go away, it just breaks down into smaller and smaller pieces.
We're f*cked.

 In Canada (and the rest of the developed world) we have the luxury of regular trash collection, right from our doorsteps. Many parts of the developing world, especially urban slums do not. The problem of plastics in our oceans and rivers is largely caused by the lack of proper municipal waste collection in developing mega-cities.

 One technical term used is "exporting pollution" and it doesn't just have to be sending your trash away for less environmentally friendly processing, it also includes when domestic regulations restrict a component, process or waste; therefore causing the consumer to purchase it for another country.

As a manufacturer whom chromed steel tubes in California, regulations made the product so expensive and reduced its performance so much that it was 2x as expensive and lasted 20% of the same lifespan. Therefore it was more fiscally responsible to buy the chrome plated finished component form Thailand/Taiwan or china rather than produce it responsibly here.

Furthermore products that are more environmentally friendly are actually less environmentally friendly if they last half as long, for example paint, if it lasts half as long to reduce emissions 40% you will actually create 20% more emissions in the products lifespan when you repaint it.

These are inconvenient truths surrounding the climate change debate, most countries only control their emissions domestically, while outsourcing the products to less controlled countries that poisin the environment more.

This is my TED talk, please downvote me to oblivion.

 Trash barriers on the river is a great idea, but very dangerous to any wildlife that may still live in there. Here in Melbourne Australia this was tested in a few areas. At first it appeared to be a great success, but they do catch everything above a certain size, including wildlife. They ended up cancelling the trials when they were found to be catching and drowning endangered Platypus' as well

 Its France, you need something to cut your cheese with while picnicking at the side of the road waiting for the TDF to come past. How else would you buy a knife if they were not for sale ?

 Surely a good french cheese should have a thick pouring consistency. The knife is for cutting la baguette to serve it in and chunks of saucisson. Damn that's making me hungry.

 Tell that to the corporations that use needless amounts of plastic to keep their profit margins as high as possible, instead of using paper, glass or metals, all of which are far more easily recyclable than plastics. Capitalism will kill us all, if the microplastics don't do it first.
  • 17 6
 More often than not your probably find using plastic has a lower carbon foot print (This isn't generally because companies care about this, it simply costs them less. The more energy it takes to make and get us the product the more money it will cost them/us and as most energy comes from carbon... I'm not saying make everything from plastic but it defiantly has its place (which is not in a river...) consumers over consumption of all things is the real issue. buy less.
  • 3 3
 That would be 2 easy and then how would they make money off selling you water selling you water?
Funny thing is when we were kids in the summer we would leave the house first thing in the morning to go explore the woods and a lot of times didn’t come home tell dinner if we really got thirsty we would drink out of the creek or eat snow no off us got sick and if we were dehydrated we never new it. Different times I guess.

 @Bungalow-bikes: While consumers are not blameless they are very much not the root cause of the problem. Consumers are adaptable, they take what they are given. If everyone's drinks and packaging suddenly went to glass and paper, do you honestly think people would consume less? Even at a slight increase in price? I think not. Many towns in my region banned plastic bags, sure they complained about paper bags for about a month, then they got over it, brought reuse-able bags or shut up and got on with life. This is very much a corporation/capitalism problem, and it is very much the only way it can be fixed, along with regulation. Needless to say I love that people are trying to find solutions to problems such as plastics in the ocean. But the real solutions are and always have been with corporations not individuals.

 @ashlemon: it’s much worse than you can imagine. There are island nations that don’t have infrastructure for dealing with their garbage so the garbage is dumped on the beach for the tide to carry away.

 @mfoga: I totally agree, that's what I do. It just sucks that some people are forced to choose plastic bottled water when they would just as happily choose boxed or glass bottles water if that's what was available to them. I'm not saying plastic is the devil, it has plenty of great uses, it's just used far to often for small profit gains when other actually recyclable materials could used.

 @MegalodonMatt: if you should be thinking about single-use glass bottles: they are much (!) worse than PET bottles, due to material weight (ca 180g for 0.3l size vs. ca 10-15g of a PET bottle or alu can) and the energy needed for initial production and re-melting.

Reusable glass bottles are better, but only in regional low-distance collect-and-refill solutions. (that need to be set-up in the first place)

1. Avoid bottled water.
2. Don't throw into nature FFS.
3. Recycle it.

 @MegalodonMatt: I'm a hypocrite on the subject. Until countries like China, India, etc start jumping on board and taking it serious its pointless to worry. At the same time I fully support getting rid of useless clamshell packaging thats far to big for the product

 @MegalodonMatt: The problem is the 'obvious solutions' are often the wrong solutions, when you take the time to zoom out and look at the bigger picture. like replacing Light weight easy to recycle plastic bottles with heavy weight glass bottles (that require more energy to recycle, due to there much high melting point) or worse replacing with a heavy weight non recyclable plastic "reusable bottle" that will unfortunately inevitable thrown away due to fashion breakage or hygiene. there a lots of articles that have detailed the unfortunate environmental impact of "bags for life" (carbon foot print, consumption of water, actual life span etc...) & paper bags have a huge requirement for water in production/recycling of them. Capitalisms search for profit naturally forces company's to try to use less energy and less material because that reduce costs wins them business. consumers need to consume less - switching to "Greener" materials is often just green washing to make consumers feel better about buying something they probably shouldn't be buying, in my opinion.

 @Bungalow-bikes: it's been my understanding that almost no plastic actually gets recycled in the US. For years it was sold to China (being shipped back across the world) but over the past few years it's value dropped so much as a recycleable commodity that they no longer buy it and instead it piles up in warehouses all around the country, I guess, waiting for the value to increase? There's really no end game when it comes to plastics, we were sold a lie by the oil companies, go figure. Then when you factor in the ever increasing argument of micro-plastics finding their way into our food, water and our bodies, causing cancers and infertility...I guess I'd take a product with a slightly higher carbon foot print (glass, paper, metals, etc) that doesn't end up trying to kill me (and other animals) Like you said, it's a complicated situation, one which I don't fully understand. But what I do understand is that capitalism is happy to kill people as long as doing so fits within the budget, it's just business, and humans are just a number on a computer.

 Re: Erzbergrodeo

What's the appeal of navigating a clumsy 100kg MX bike through a rock garden a crawling speeds? I don't get it. That sport is so weird.

Also why aren't those MX bikes electric? Instant torque and perfect traction control would probably be way superior to a revvy two-stroke engine and a friction clutch.

 Pol Tarres would agree with you,that´s why he did it in a 700cc Yamaha Tenere trail/touring 180 kg bike. Some of the downhills are crazy,many of us would look them twice to do it in a DH/enduro bike,but doing it in a 180 kg bike is something else.
Many of the moto riders would think the same about what we do in the bike.
  • 2 0
 @RadBartTaylor: An electric motor doesn't even require a clutch; output torque can be proportional to throttle position, e.g. EVs that can be driven using only the throttle pedal.
