DURA-ACE clincher tyre wheel sets WH-7850-C24-CL and WH-7850-C50-CL which have spoke plugs rather than rim tape have, say Shimano, been found to be more likely than usual to puncture. According to the company the problem can be solved by replacing the spoke and valve plugs on the affected wheels with Shimano’s own high pressure rim tape. Shimano is advising anyone with the affected wheelsets to contact their local Shimano dealer or service centre where they will be provided with the correct rim tape free of charge. A guide on how to replace the spoke plugs with the relevant rim tape has been posted on Shimano’s website. However, before you rush off for some rim tape it is worth checking that your wheels are affected – not all of the two wheelsets with these product codes are. It depends on when they were manufactured. So if you’ve never had a puncture (lucky you) how do you tell if you need to get some rim tape? Well, if the product code number, printed on the rim, is on a red background you don’t have a problem, if it’s on a black one you do. If your wheels have a round silver sticker near the valve hold, no, we don’t know why they’d put a circular silver spot there either, but it’s good news: you’re in the clear. It’s also good news if there is a round silver sticker next to the Dura Ace logo on the right hand side of the wheel. If you have either of the WH-7850-C24-CL or WH-7850-C50-CL wheelsets without the good news silver stickers or the red background for the product code contact your Shimano dealer or service centre for some rim tape.
Check your spoke holes if you have Shimano Dura Ace WH-7850-C24-CL or WH-7850-C50-CL clincher wheels

Video of crash mentioned above: https://www.youtube.com/shorts/NfCdbwPdK9M
I do try not to enter into discussion with you on this Bert, because I know you will never change your stance one iota, but I've crashed a motorcycle at around 35 mph and hit my head on the kerb hard enough to compress discs in my spine and tear neck ligaments but above the neck I came away with nothing worse than a mild concussion. If you're going to tell me that I could've done the same thing without a helmet on and walked away with the same injuries I'm going to have to say that's nonsense. Anyone who's ever watched MotoGP will have seen riders coming off at high speed and smashing their heads and getting up to walk away. Just as an example, check out this crash from Marquez this season: up in the air at high speed, down straight on his head, got up and walked away. Screenshot below, I'll post a link to the video as a reply so I don't get stuck in link quarantine. Again, it's clearly nonsense to say the helmet hasn't worked when someone's walked away from coming down headfirst on the tarmac from a height at high speed.
To understand any active travel scheme, you only really need to ask one question: “How does this impact on free/cheap parking?” In this case, it explains the majority of the ‘controversy’ It is not long since someone sat on a bench in RVP was hit by a driver and hospitalised. But do let’s worry about those “speeding cyclists”. https://www.somersetlive.co.uk/news/somerset-news/teenager-hit-car-sat-bench-11070561.amp
@kingleo I've still got a label from a helmet, and it says something like 'this helmet may not protect you in all foreseeable accidents' which just gives them an out when someone claims that it didn't work. Not sure the professionals should wear motorcycle helmets, as they are heavy, very well insulated and only work up to about 16mph: not sure you'd win too many TdF's at that speed, and anyway, your brain would fry.
@EM69 To be clear, my comment relates specifically to the new Sirius that came out a few months ago. As far as I can tell, the new Strada retains H/M/L steady levels in program 1.
@mitsky If I were a police officer involved in implementing the scheme I think I would find it very hard to hear the details given by those self-important/rich/arrogant (in the City these terms may be synonymous) enough to accept the fine, meaning they had to be repeated multiple times. I might also experience frequent pencil lead breakage and a difficulty in finding the right form to fill in, perhaps also frequently breaking off to use my radio ("Excuse me sir, it's an important message from my superintendent. What's that sir? Soya latte, a pain chocolat and a blueberry muffin, right you are sir"), so that by the time the paperwork was completed and they had been sent on their way with a fine those who chose to stop and watch the video had already departed.
@Mr Blackbird always heartwarming! ❤️ Do you remember Nick Clegg declaring his love for David Cameron in a rose garden? No, wait, was it his love of a better seat in parliament and more solicitous lobbyists? Or more recently Nigel Farage declaring his love for strong, manly figures like D. Trump, V. Urban and V. Putin, before declaring his love for money and his lack of snobbishness about its origins? (Would that some of the others were so candid - although eg. Lord Mandleson didn't need to declare his love for wealthy, dodgy businessmen).
@eburtthebike Hmm; Lost my original reply. I think the key point to (likely pro helmet biased research given funding sources etc) for ski helmets is that basically all research says they make no difference to fatals and minimal if any difference to serious injuries (despite claims of massive effectiveness). (Outside of some older research into racers where a reasonable look is the benefit is related to secondary impacts - the helmet doesn't prevent injury, it prevents the distraction after racers get it wrong and clip a gate (fibreglass pole on a spring) head first that leads to subsequent dangerous crashes when they lose control at 80-100mph...)) Showing part of the problem with 'XX% reduction in all injuries' claims (which they now seem to use in ski helmet promotion to imply its a XX% reduction in deaths or hospitalisations rather than because 90+% of injuries are minor cuts from catching a ski edge/pole in a fall where treatment is clean and put a plaster on it...) A 70% reduction in incidents with total harm being cuts and bruises can easily be a 60% reduction in all injuries because theres likely dozens of serious injuries for every fatality and dozens of minor injuries for every serious injury (and dozens of near misses for every injury...)
@MatzeLoCal Indeed. It's notable that the agency's excusing of itself makes much of the fact that the athlete did not raise any concerns; in such circumstances, where the athlete's thoughts and actions are going to be severely disrupted by her grief, it shouldn't be up to her to raise any objections. As soon as the testers were advised of the circumstances they should have immediately offered her the option of postponing the test. If they had and she said no it's okay to carry on that would be some mitigation, but clearly they didn't.
Received my Strada 13 SB on Saturday, just in time for an overnight ride. Worked flawlessly. The Aktiv function worked well. The only issue was the Ant+ connection to my 1050, but i'm placing that squarely at Garmins feet!
