Slack Randoms: 3.3kg Bikes, Wireless Only Frames, 'World’s First Alloy Superbike' & More

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.



3.3kg Road Bike Build


We are not sure how fun this bike would be to actually ride, but at 3.3kg it's lighter than some mountain bike frames. Also, after adding a couple of larger battle bottles most of the bike's weight could be water.



Vielo Wireless Only Gravel Bike


The first of two claimed "World Firsts" in this week's slack Randoms is the launch of Vielo's new V+1 Race Edition Gravel Bike that has been purposefully built for wireless drivetrains. Offering a very clean look, the only cables on this bike are for the brakes that are completely internally routed through the bar and stem and into the frame.

The V+1 Race Edition is perhaps the first wireless-only gravel bike and it features a very light 880-gram frame and has been designed to work with SRAM's eTap AXS drivetrains. Vielo founder Ian Hughes said “The V+1 Race Edition follows the same design ethos as the R+1 Alto road bike. If you’re going to build it with a wireless group set, then why not make the frame exclusively wireless?“

Specialized Launches the "World's First Alloy Superbike"


Specialized has launched a new Allez Sprint road bike that they claim through 41 years of development is the "fastest alloy bike ever created".

As part of the development of the new bike, Specialized has built what it calls the most complex headtube it has ever made and is cut from a single piece of alloy before being mechanically formed to create a more aero shape.

Specialized says that moving the weld points back from the head tube removes "redundant material from the head tube, promoted a uniform result across all the bikes we built, and minimised strain on high-stress areas of the bike.” The one-piece bottom bracket and downtube are hydroformed from a single piece of alloy on the new frame and remove two weld points from the previous bike. This is said to improve power transfer and structural integrity.




Thief's Stash of Bikes so Large it Can be Seen on Google Maps


Police in Oxford have arrested a 54-year-old man who had been stealing bikes for five years and storing them in his garden. The suspects' collection of stolen bikes had become so large that it was visible on Google Maps, a fact that actually helped the police find him.



Vorsprung Suspension Attempts to Measure Climbing Efficiency and Rolling Resistance


bigquotesOver the past few years there have been some interesting efforts throughout the bike industry to investigate and understand climbing efficiency. This is understandably important to people, because if you're getting to the top of the hill under your own power, you're going to be spending much more of your time climbing than descending. There's a fair bit to consider, particularly when it comes to measuring efficiency - which turns out to be very difficult to do with bikes.

We dig into some of the attempts to measure climbing efficiency, as well as rolling resistance.

How Strong Are Bolt Threads?

 And leaving them outside, presumably to grow in the garden (of Eden?).

 This is the "World's first Pinkbike comment"... I think I figured out the secret, just put it in quotes and it doesn't have to be true. Anyway, Pinkbike please contact me about where to send my award, thanks.

 First wireless only gravel frame? A shitload of custom framebuilders probably disagree, including myself....
  • 6 0
 It’s also splitting hairs as specialized Aether was wireless only when it launched. Road, but still in the ballpark of a gravel bike.

 It's not truly wireless without wireless brakes Wink
I think the first company to offer wireless brakes will earn a shitload of money, cause we all know that the look is the most important aspect of any $5k+ bike.

 @lkubica: bike has hoses not wires for the brakes.

 @lkubica: They exist:

But probably not if you ride hard.

 Why Cycles' R+ was wireless-only for a couple years, full production model too.
  • 7 1
 @daugherd: Shifters have cables, not technically "wires". All bikes are wireless!

 dose it come with wireless brakes too

 @vRidge: I feel like this is one of those all cables are wires but not all wires are cables.

 Back in the 90s when Easton and Columbus made aluminium tube sets there were plenty of ally super bikes I suppose we butt welded a frame doesn’t work for marketing at specialized

 The higher end Kleins had AL sandwiching boron-carbon fabric, that was then baked in during heat treat. The magic was in forming the tube(s) while drawing and introducing the fabric. Dafuq kinda black magic was that?!?!?

 Pretty sure Cannondale has done many alloy super bikes.

 3,3 kgs bike without pedals!!!!!!! Cheaters!!!!!

 No bar tape either...

 Can it still be called a bike if you can't ride it?

 Vorsprung Suspension's video isn't an attempt to measure anything. It's an explanation of how difficult it is to do so.
  • 5 0
 To put a finer point on it, I think it was an explanation of why the efficiency tests don't have any value whatsoever, but I could certainly be wrong.
  • 2 0
 @dancingwithmyself: Exactly, percieved efficiency is probably more correct than measuring watts at the pedals on mountainbikes!

 Fok, you’re being too kind there !
It was incredibly dull and useless.
Keep your chain clean, blow your tyres up and flick ya lockout if you’re bothered about spending 5mins extra pedalling.

 Come on pinkbike, do you're homework. The lightest bike was in 2012 at 2.7kg antranik.org/worlds-lightest-road-bike-at-2-7kg

 3,3kg bike... it's just a bit more than both my tyres and a bit less than Danny Hart's balls.

 Most interesting part of this is the nut and bolt testing.
  • 7 0
 Was it the hard bolt and soft nuts that you found interesting?
  • 2 0
 @stage-a: hard bolt
  • 1 0
 Loved how the soft bolts/nuts all deformed plastically (except that last one), while the hard bolt/nut failed in a brittle nature - as expected from what I learned in materials science so many years ago but still in a surprising 'oh yeah, forgot about that' way.

 That steerer assembly of the light road bike is a recipe for disaster. All the jumps in stiffness in one place (stem end with no spacers, cone of upper bearing) and a totally useless expander. Combined with superlight fork steerer. What could possibly go wrong?

 "the only cables on this bike are for the brakes that are completely internally routed through the bar and stem and into the frame." The Vielo has cables? Mechanical disc brakes? I could only find is spec'd with SRAM Force.

 Now I need a hydraulic press...
  • 1 0
 BigKahuna: Do some recon, and see what a press that size with all the readouts, etc will cost, and you'll get over your "want".

 I don't want any wireless electronics on my mountain bike in the least, but for some odd reason, wireless electronics makes perfect sense on road bikes. Lol.
  • 2 0
 Because road bike cable routing on new bikes makes tight bends that add lots of friction
  • 3 0
 But I’m with you on mechanical. I don’t want to charge any more batteries, there are already too many in my life

 @cdst: It just looks super clean on a road bike.

 Can someone fact check these worlds firsts please

 No because that would be a world first

 A real pro bike builder doesn't pull the tape to tare it, they cut it!

 would anyone still buy a road bike with v-brakes? Thought that was a thing of the past? Also, got a feeling if I sat on that, that would be the end of 12grand...

 Wow I just spent 10 minutes watching a guy smash bolts. Could be some of the best content on YouTube

 Moots has been building wireless only gravel bikes for years Im sure they aren't the only ones.

 No talk on slack about an XC fantasy league by any chance?

 That’s a big wave

 How is that "wireless" bike noteworthy?

 It’s not
