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

@Xenophon2 I agree. I tried a different route from Garstang to Leeds on Saturday to avoid the Death Highways from Barnoldswick to Skipton. I had to turn off Hazard warnings on the 1040 because people have ruined the hazard facility by warning about every pothole, instead of only the bad ones. UK roads are full of them, and the red Hazard was turning up constantly. Similarly, radar is useless in the UK because nutter drivers are everywhere and the alarm will be going off all the time. I'm convinced this is a good radar and it's what I'd get if I had any use for it. I'm pretty sure it would have warned me about this Stagecoach bus on The Lancashire Terminator Express, and lots of the other vehicles as well- then what? ttps://upride.cc/incident/px12dnv_stagecoach41_closepass/
It's just the same on cucumber growers websites. Only last week, a Tuesday I think it was, there was an article on growing courgettes. I don't grow courgettes. I was livid and thought I was going to spontaneously combust. Luckily my wife knows the signs - steam rising from my boots, speaking in tongues- and was on hand to throw a bucket of water over me. She always seems to have a bucket of water handy. And as for red tomato growers websites? Don't get me started.
What size of golf balls though?
Given that humour, as defined by no less than Charlie Chaplin, is someone else's misfortune. it is clear that anyone who makes a joke should be fired. Which reminds me of the terrible joke about what the ring master said when the human cannonball died "It'll be difficult to find another man of his calibre." Fire me now to save time.
@Mr Blackbird Yes, I've been on the rugby field when a sudden storm of about 3mm stones erupted, like being shot by a thousand air rifles at once and as you say, the temperature plummet was incredible. Memorable also for the sight of props who hadn't broken above a jog in two decades and who thought you were a wuss if you went off for a mere broken arm suddenly doing creditable Linford Christie impressions in the rush for shelter!
@Rendel Harris I just finished watching a recording of today's stage and the hailstones appeared to be somewhere around blueberry sized. Possibly large enough to cause somebody to crash if they rode over one at the wrong angle. A few years ago I was riding a time trial on the A428 in Cambs. It was around 18 - 20 deg C. At around the half way point the heavens opened. The temperature must have dropped by about 10 degC almost immediately. Within about a minute, I was completely soaked and riding through about 10mm deep water on the carriageway, with my visor fogging up. The worst thing though was the feeling of shock. Had I been near the HQ I would have abandoned. The Vuelta riders must have experienced something much much worse than me, especially as they will have been acclimatised to 30+ degC in recent weeks. Hopefully none of them will get ill as a result of today - it was only stage 3, so pressed their immune systems aren't yet too stressed.
Sounds like this bike should have 5 stars 🤩…why only 4?
Poor you! 😂 Humans have been cycling gravel roads since bikes were invented. Tarmac is not the definition of road.
Hailstones the size of golf balls Ryan? It was bad but I've seen a "golf ball sized" hailstorm (in Spain, as it happens, from a safe shelter) and they smash glass and can knock people unconscious, often with skull fractures - no way would the riders have been able to carry on until they found shelter in that type of storm, it would have been every man for himself under the nearest tree or rock.
Oh, get over yourself. For many of us, the shit state of UK roads means that a gravel bike IS a road bike now.
