When they're more expensive than the walkable cleats, there's not much point. :(

Looks like they have gotten more expensive.. There are, however, a number of use cases for V2 style over Walkable-- the later, can be made "Walkable" by Kool Kovers or their inexpensive Chinese knock-offs and can be "protected" for short walks by any of a number of covers from Speedplay and 3rd parties. For recreational cyclists the Walkable is perhaps a big plus-- the tiny bit of extra time to clip in does not matter-- but also with a downside: the rubber bits can fall offf (just like the Kool Kovers and copies but lacking a 3rd party replacement they are also much more expensive at almost 1/2 the price of a new pair of cleats).

Got a link for Pave V2?

(looks like the supply of V2 Red cleats is also drying up in Europe)

Amongst the Walkable.. What is interesting is that

https://r2-bike.com/SPEEDPLAY-Pedalplatten-fuer-Zero-Pave-Walkable

only sell the Pave and sell it for the Pave, Zero and Zero Aero..

I couldn't find any info about stronger springs

Getting information from Speedplay is difficult. The Light Action, for example, seems to use a softer spring Interestingly the difference in the Track variant is in the pedals themselves-- which effects (slightly) the way the release works-- and not the cleat.

I'm not seeing many v2 cleat options. Seems most are walkable versions.

In Europe the standard Zero V2 seemed to have vanished from the distribution chain. All I see now for the Zero are the (more expensive) walkable versions, the (even more expensive) Nanogram cleat and the Pave (which I see in both V2 and Walkable variants)..

I asked explicitly what the differences are-- I also use the Speedplay pre-Pave cobblestone pedals so was curious about the new cleats. In a message I recieved in 2014 from Speedplay:

Hi Edward,


Thank you for contacting Speedplay.

There is a difference in cleats.

You can use a Pave cleat with Zero Pedals, but not Zero cleats with Pave pedals.

Any further questions please feel free to contact us again.

This reckons they're the same, just red. Although it's the old cleat.

I thought you were looking for the V2 cleats. (Pave still seems widely available in Europe in both standard and walkable variants)

Pave vs. Zero?
The dimensions are the same but Speedplay do claim they are different. I was told (by Speedplay) that while the Zero can use either the Zero or Pave cleats, the Pave demands the Pave cleat and should not use the Zero's cleat. I can only speculate from this that the C-clips are slightly different-- probably a bit stronger.

So, any more opionions, is there a stack height difference in the walkables or not?

Have you also considered using the Pave cleats? The difference is in the C-clip and it might be perhaps better for you...

Perhaps the issue i have encountered a few times is the difference between V1 and V2 adaptor plates

V1 vs V2 was just the curvature of the adapter plates. They switched to offer the V2 adapter to better fit with its contemporary generation of shoes. On a Time shoe-- 4 hole bore-- there is no difference between V1 and V2 since one does not use the plates. With look bored shoes.. If your shoes had a good fit with the V1 adatpers they would continue to be the better fit.

Is there any difference in stack height between the v2 cleats and the walkable Zero cleats?

Why sure there be? Basically they just slightly modified the metal top bit and added a plastic walkable top. The retention mechanism is unchanged-- like adding a Keep on Kover to a V2 (which differed from the v1 only, I think, in the adapter plate for 3 hole shoes).

Anyone got one spare Coffee Cover I could buy/have? I lost one of mine!

Sure. Light Action but don't see a difference... have enough spare.. brand-new in their orignal Speedplay packaging.. just postage (probably 3.20 or 3.70 EUROs worldwide for a pair)..

The "safety operator" of a self-driving Uber car was watching TV just before the vehicle was involved in a fatal collision, a police report reveals.

This is part and parcel of what I seee as the biggest technical hurdle to self driving cars: getting systems good enough for Level 4 without crashing and burning. As ADAS improves the cognitive demands for the control driver increases as the task become more and more boring-- perhaps something for a specific profile within the autistic spectrum.

Rims.. old school Mavic Pista or Reflex, Ambrosio F20, Araya 16B Gold, etc.. and same from Fiamme, Super Champion, Nisi.. there is still a lot of NOS about.. or just used track wheels since so many have gone over to the dark side with boutique wheels..

Why? Soyo Gold Star tyres are not really good. Their point is just to level the playing field. You can get them "use only one race" from a number of Japan exporters... cost is roughly $70 each (half the price of brandnew from Japan).. Within the EU.. Velodrome.net has them for 150 Quid each..

We are talking about a NJS build for the road and not to compete in the Keirin circuit, right? If it is for the track.. I'd grab some Vittoria Pista or maybe if they are for outdoors.. some Continental Sonderklasse.. If for the road AND you really want Soyo.. they do have a number of road tyres.. including the Upstream which is a very nice "training tyre".. cost is around 80 EUROs each plus shipping from Japan..

I think 'custom' as in if you want colours of the canvas and leather they already do for a certain bag model but in a different combination.

Still. Carradice these days has so many colours.. Not that I'd want anything other than black.. Does the custom cost extra? I'd be curious about the black leather. The white leather belts on my Camper looked new like a kind of buff leather with a waxed front surface. They have worn extremely well despite rain, sleet, snow and burning sun. Don't know if they are still using the same leather process. The black leather I assume is blue split (chromed)..

two custom Camper Longflaps (black with black leather) for me and the Mrs.

They do custom?? Would not mind another Camper.. mine is some 25 years old and still my favourite given its capacity. I bought an 11l Zimbale but use it instead as a front bag with a Nitto M18 rack.

"consumer tubulars" have butyl tubes.

Team issue race tubulars, Competition, tempo, Sonderclass have latex tubes.

This is, at best, a half-truth. Most of the team issue Continental tubular tyres ("Pro Limited" and friends) habe butyl tubes. These tyres are finely tuned to special applications. Continental's researchers believe that (their) properly formulated butyl tubes are superior to latex. The standard competitions (and ProLtd) get a very thin buytl inner-tube ( 0.4 mm).

In order to, however, meet the wishes of some riders (and their mechanics) Continental also make some of these tyres with latex.

There is a difference in the ride and also unsurprisingly in the air retention time .

Have you really compared ProLtd latex with ProLtd (non-latex) designed for the same event?

Seriously tho someone try these

The Syzr?
I have them on my belt-drive bicycle (matched with Quoc Pham Hardcourt shoes) .. Feels nearly en par with road pedals and shoes. Not quite sure that they'd be suitable for extreme off-road MTB use-- a discipline I know little about and whose gear I neither own nor have practiced with-- but as a "urban" automatic pedal they seem a good choice-- whell.. I selected them :-)
I think one need view them as an alternative to ATACs.

Add: I think the main drawback of the Syzr are their retail price. With street prices still floating above £135 / 150 EURO they are a bit (like everything Speedplay) expensive..

Mud and speedplays are not friends. Put your foot down once in mud and that’s it, you’re not clipping back in until you’ve cleaned out your cleats.

That is the point of the Pavé variant.

Makes sense. It still seems very bad that they'd allow a blind spot that big though, no? In terms of lower speed incidents? Then admit that.

Cars don't need LIDAR. One can do SLAM without it-- see. for example, https://vision.in.tum.de/research/vslam/lsdslam.
You don't need LIDAR to "see". LIDAR is not magic. 850-950 nm is not really ideal-- except that one can get emitters out of silicon. Radar, ultrasonic, optical cameras and other sensors should-- and I think we'll increasingly see this-- be sufficient. Radar works better than 950nm LIDAR in snow, rain and fog. Optical cameras can "see" color and constrast. Ultrasonic has very short distances but works pretty well in all weather conditions.
Including a LIDAR on the roof is, I think, a good solution this week. Even if they get down to under $250 (and the Velodyne units start at around $4k and some are as much as $80k) and reduced in size there is still no need to have them by the 6 pack.. Don't underestimate the power and potential of optical image capture.
There are also a number of interesting optical camera capture techniques on the horizon. See: http://web.media.mit.edu/~guysatat/fog/

that they don't have enough sensors and have significant blind spots:

Cow droppings.. I would argue that one does not need LIDAR.. and there us a lot of work on new approaches to LIDAR...the article clearly has no idea of the current state of R&D .. there might have been some serious problems with the Uber car but having only one LIDAR on the roof is probably not one of them...

gree with this; I'd say dealing with automation is nowadays the biggest single human factors problem in aviation,

My take is given right now what we need is a lot more data I'd leave off the "comfort" and give the impression that drivers and pilots alike are in full control. If a driver does not really know when they are in control they must assume that they are always in control and must be alert, use all their senses (including tracking all the vehicles on the road, making a number of predictions on the characters driving those vehicles and what their potential next moves might possibily be to put one in harm's way etc.) all all times. The question, of course, arises: "how does one know when in robotic mode to suspend autonomy and handover control to the driver-- who at the instant might have thought they had control but did not?" Since we can easily track the drivers pose and head position as well as their affective state, heart and respiratory rate, I conjuecture that we could probably find some appropriate conditions where autonomy is distrupted and control is passed fully to the driver.
The control driver in this model has nothing to get bored of. In fact, I might even suggest that they are kept under higher cognitive demand than a driver in a normal sedan. As some pilot, resp. cruise, modus proves itself "better than humans" one can then enable them to be deployed without the "guessing game".. so over time more and more features could be "enabled"-- resp. the control game disabled.

I have come to the conclusion that the current model of driver as control backup is only appropriate when the robotic vehicles perform poorly. As the vehicles get better and better at their task it is increasinly infeasible to expect the human driver to take control when needed. Last week's fatal Tesla crash just as the Uber accident are. as I'm increasingly convinced, sympton not of problems with the AI or sensor but of UI/HCI. The human interface is fundamentally flawed as it demands that the driver be alert and cognitively able to take command. We need, I think, to rethink our current approach and develop a new set of rewards for the driver as long as the state of the robotic control is insufficient (up to level 5) to work without one.
Until this is solved or adaquately addressed I argue it is negligent to put out cars with increasingly adavanced ADAS (as the case of the Tesla) or continue to conduct self-driving car tests. As this becomes more and more widespead, without the needed paradigm change, we'll see more and more nasty problems. Will the rate be higher than without AI? I don't know. Even if it is not.. it would be clearly significantly higher than need be...

And when will the Sword of Damocles fall? I think within the next 5 years.

How so, through automation? I'm assuming you mean that initially most of these vehicles will need to be 'supervised' by a present driver as such. You see an oncoming wave or a gradual progression?

I see the occupation of lorry driver as the first to go into fast decline. The industry employs alone in the UK 2.2 million people - the UK's fifth largest employer. That is a significant labour pool about to slam into a wall. How many of these people have skills or abilities that will allow them to transfer to other forms of similarly renumerated employment? Demand for people to handle the "last mile" will continue for awhile but those jobs are increasingly as sub-contracted "self-employed" with debt as entry ticket (and declining earnings)..

Right now the industry is lacking in drivers. Demand is high but as soon as automation-- and the shortage is just more fuel to the adoption-- takes hold these jobs will go the way of the dodo. If this is not the stuff for a mental health crisis in the making...
