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.




UCI Legalize Tire Pressure Management System


Ahead of this year's Paris-Roubaix, the UCI has given approval for riders to use a real-time tire pressure management system. The system in question is Scope's Atmoz which allows you to adjust your tire pressure while riding.

The pressure control system lets you press a button on your bars to add or remove tire pressure depending on the terrain. There are not many details on Scope's system but it sounds like it uses a pressurized air tank that releases air with each inflation, this means there is only a limited number of uses before the system needs recharging. The system attaches around the hubs and uses a pneumatic hose and unique control valves to adjust the air pressure in each wheel.

bigquotesAuthorised in line with article 1.3.004 of the UCI Regulations, the tyre pressure management system is controlled by buttons on the handlebar and uses mechanical valves to regulate airflow between the air reservoir and the tubeless tyre. The system does not alter the structural integrity of the wheelset and does not contain any moving parts or compressors… In line with 1.3.006 of the UCI Regulations, the tyre pressure management system is also available commercially for all people practising the sport of cycling.— UCI

Scope has the system available to buy now, but it's not cheap at €3998. You can find out more about it here.




Nino Schurter's 1st and 33rd World Cup Wins


After taking his first Elite World Cup win at Dalby Forest in 2010, Nino Schurter finally matched Julien Absalon's all-time win record of 33 in Brazil last weekend.




Jackson Goldstone vs Amaury Pierron at the Lourdes DH World Cup


With Jackson Goldstone getting a five-second head start, see where Amaury Pierron makes up the time to cross the line at the same time at the Lourdes DH World Cup.

Championship-winning skydiver Maja Kuczyńska shows off her incredible skills at this year's European Championships.




Are Metric or Inch bolts stronger?


bigquotesHow strong are hex nuts, bolts and bolt threads in inch and metric sizes? Are machined billet bolts stronger than store ones? We are going to use our 150 ton hydraulic press and 240 force sensor to find out!— Hydraulic Press Channel




Highlights from the Nines 2022


bigquotesThe grand finale of The Nines 2022 presented by Falken brings together all the vibes and action from a whirlwind week in Crans-Montana, Switzerland with an immensely talented group of riders and an unforgettable setup. It doesn't matter if you are a skier or snowboarder, male or female—in this edit, as at The Nines itself, everyone’s united in one big happy shred family.— The Nines

 UCi and Legalize are two words not often seen side by side

 It's true l. A better representation of their view would be 'the UCI have not ruled out banning tyre pressure management systems at this time under very specific circumstances but all other instances of this or indeed anything else is absolutely banned'

 The bolt test video is garbage lol. Actually quite comical. They don't say what grade any of the bolts are. Are we comparing grade 8 to 10.9? Also bolts are not typically tested by being pressed. Usually a quality or failure test would pull the bolt until it snaps...Tensile Strength... Bolts are essentially a pull spring and when properly torqued create the desired clamp load. Failure happens when they pulled, stretched beyond elasticity. Other failures or tests are for shear strength, Which has a lot more variables. The two most simple applications of shear strength are single shear plane or double. Please someone give me a real world example of bolts being used in an application where they are pressed downward lol.

 Screw type jacks use threaded rods in compression to support their load.

 @natemeyer: Bolts, not thread forms.

The only "Bolts" I can think of are normally under compression are adjustable legs on a table or machinery to level them.
  • 4 0
 The video specifically says it is a test of the thread strength. For this it does not matter which direction the force is. Using a press allows testing the thread strength without having the bolt stretch and break before the threads do.

 @Douglas4130 It's not scientific research, or anything of real value, and not claiming to be. It's just for entertainment. Also as far as the threads are concerned, what would be the difference between pushing or pulling?

 Can't believe UCI approved the real time tire pressure product. Part of the racing strategy is picking tire pressure. It should be pick a tire pressure and accept any consequences good or bad.
  • 10 1
 What used to be cool about racing is what made it difficult. Now it's just full of gadgetry to make it as easy as possible and it's removing the human element.

 Hacking a competitor's system to make their tires suddenly go flat would amuse me. Checks specs... "Communication: ANT+ / Bluetooth". Oh yeah... there we go.

Now all we need is handlebar mounted IR "guns" and detectors on the backs of every rider. Wire it up to flatten the tires when you get hit and re-enflate after a set time, and you've got yourself a whole new sport... dogfighting on bikes.

 Doing that on tandems would be the best thing ever lol
  • 2 0
 @MrShreddypants: Oooo... then you'd have a pilot and a gunner. You have a group of tandems trying to make it from point A to point B, and a group of single rider bikes trying to stop them like fighters attacking bombers. [searches Arduino projects] yep... I figured someone would have thought about combining laser tag and bicycles, and here it is fritzing.org/projects/laser-tag

 in the summer that skuggling guy is a run of the mill ex-Boulder hippie street busker, except he moved from Boulder to a tiny town in Idaho. The ski juggling is impressive, though, especially the moguls and the 360 while juggling. Not something I personally need to see more than once, but impressive none the less.

 Wait, uci banned pinky bar ends but is cool with self inflating/ deflating tires? Am I missing something?
  • 7 0
 UCI felt like the self-inflating tired were expensive enough to allow. They felt it would be good to keep the riff raff out and allow only dentists and their kids to compete.

 I’ve always thought that pressurised frames powering pneumatic motors in hubs or BB’s would be the easiest way to add a motor to a road bike, and pass the UCI “testing” and scrutineering. Now that UCI has legalised a reason to have pressure vessels and plumbing on bikes, I can guarantee that they will make an appearance at some major races/tours this year.
  • 1 0
 Well, the amount of energy one could store in such a pressure vessel is minimal...

 its amazing how different im assuming two different cameras/setups made both those runs look nothing alike jacksons run looks much smoother so gives the impression of it being slower when the difference in time is imperceptible?

 @barp: Grammar refers to the ways we put words together in sentences to form meaning. Punctuation refers to all the symbols that enhance sentences and add clarity.
c*ntiness achieved, whatever you were going for-failed.
  • 1 0
 @sonuvagun: Did you not actually read the definition I copied from the dictionary? The definition that was literally the first one listed for the word in question? Punctuation is an aspect of written language.

I'm not even mad. I feel sorry for you, going through life so needlessly angrily.
  • 1 1
 @barp: Dictionary? Which one?
You know different users have different search engines and that results in different people getting different results as their "first one listed."
I'm not even mad, I just feel sorry for you that you project your feelings and experience on every one else.
Angry? Dude, that's you. Go back to your noodle-arm life, you've got nothing interesting to say.
  • 1 0
 @sonuvagun: Wow. Yeah, you're not angry at all; you're the happiest, chillest aspiring reference librarian I've ever interacted with. And not even a hint of toxic masculinity! What a super cool guy you are!
  • 1 2
 @barp: Well, if you're assuming someone else is angry for the simple fact you and he disagree on what constitutes as grammar and what constitutes as punctuation, then you're either projecting (my bet) or spend too much time with irrational people. Using the term toxic masculinity in this context is proof positive you are total panty waste. Adios Faggagio.
  • 1 0
 @sonuvagun: At least get your toxic masculinity verbiage right, dude: It's "pantywaist". And how silly of me to assume you were angry when you escalated a civilized debate over semantics into calling me the c-word. I'm not surprised in the least that a misogynist like yourself is also a homophobe, by the way. *chef's kiss* top notch bigotry
