Is this actually an issue though? I have 4 carbon wheelsets at home from 4 manufacturers, and this happens on all of them depending on the tire, or even the time. I've never even questioned it. Some will stay seated, some don't. Even the same tire and rim sometimes it will unseat itself when deflated, other times it stays seated. To be honest, I figured this was normal. It's never given me pause.da123 wrote: ↑Sun Mar 03, 2024 6:43 pmPerhaps Joe could pitch in on this? It sounds like it is an 'issue' common to the wheels given at least 3 of us have experienced it.

All of my other wheels require some significant effort to unseat tires when deflated. With my 5060 I can literally deflate and just push on the tire with my thumb and it will pop right to the middle of the wheel.
It hadn't really occurred to me to engage Panda on the topic. I'm curious to see what else you hear from them.
Would certainly be good to get some re-assurance on this in any event.

I suppose the answer to that is 'I don't know'. My concern is whether the fact that the tire doesn't stay seated and slips back into the centre channel easily as the tire deflates means that it is more likely that the tire separates completely from the rim rather than staying attached in the event of rapid deflation. The hooked nature of the rim isn't going to assist if the beads have dropped into the centre channel. I don't think anyone is trying to set hares running, it just seemed unusual to me (and it looks like to others too), that when inflating, the tires didn't exhibit the same 'snap' into place that I was used to, and then on deflation dropped apparently very easily into the centre of the rim. It would just be good to have some re-assurance either way. It appears that using soapy water on installation has made a difference to at least one other person, so I'll try that next and see whether it resolves the issue (if indeed, as you say, it is actually an 'issue').BikeTyson wrote: ↑Fri Mar 08, 2024 1:05 amIs this actually an issue though?

It's highly unusual for tubless tyres not to 'seat' firmly on the rim and fall to the middle when air is pumped out. I recall someone mentioned a Roval rim (CLX55 I think) also did this and was not well received.da123 wrote: ↑Fri Mar 08, 2024 12:25 pmI suppose the answer to that is 'I don't know'.

Is it an issue? Firstly there is the safety aspect, if the tyre falls to the middle it's also more likely to come off before the rider can stop, especially when descending. There's also the aspect of damage to the rim being caused when the tyre peels away from the side. Not good.
Looking forward to CRW addressing this soon.

That might be a good guess, but my guess is that not the complete office goes to Taipei.shorttcuteddy wrote: ↑Fri Mar 08, 2024 7:57 pmMy best guess would be that they are at the Taipei bike show
i own a pair of crw 50/60. great wheelset but the rear hub noise is loud. too loud. what grease would be recommended to quiet it down?

Was told that you need to use the DT Swiss specific ratchet freehub grease like this:

Is there a choice? I would like to know what others think.

You can use any type of bearing grease (my experience), it is just the amount you put in in relation to the "thickness" of the grease. If it is too much the engagement mechanism (spring) doesn't work leaving you pedealling in air. But it also helps if you put in a little more of the DT Swiss grease than advised to bring the noise down.Nickldn wrote: ↑Sat Mar 09, 2024 4:49 pmWas told that you need to use the DT Swiss specific ratchet freehub grease like this:

I've been using Dumonde Tech freehub grease in my DT hubs for a few years and nothing to complain aboutNickldn wrote: ↑Sat Mar 09, 2024 4:49 pmWas told that you need to use the DT Swiss specific ratchet freehub grease like this:

Did you get a reply? Usually we're pretty fast at replying during the week. Usually within 24hrs. If its more than 48hrs, hit us up via instagram DM or live chat on our website (during Chinese working hours.) These days some of the big enail providers (Gmail, etc.) are changing the way they filter SPAM, etc, and it's having some consequences.
As for the tire / rim thing. I will update this thread tomorrow. I just got back from Taipei so will do it in the office tomorrow. Basically the tires do come unseated from the hooks "easier than average" but as some in here have said, there's a full spectrum out there of how easily tires do or do not come unseated. BUT, CRW did some tests on a rolling rig (which I'll send the video of tomorrow) with the tire rolling at 0psi, including taking corners, etc, and the tire at no point comes close to coming off the rim (despite being un-seated.) How easily the tire comes on / off the rim is totally different to how easily it does or doesnt become unseated from the hooks. (The former being related to the depth of the inner groove and the radius of the outer lip, the latter being about hook size / shape and tire bead size / shape.)
Even with tire / rim combos that stay on the hooks when deflated, I would NEVER recommend riding on that. If you wanna be able to ride on flats; use tubulars.
Yes this morning I received a mail explaining what I should expect. I have seen on the tracking that the package has arrived in Germany, so I expect this week a message from the shipping co. when they will deliver.ChinaCycling wrote: ↑Mon Mar 11, 2024 2:37 pmDid you get a reply?

Thanks for explaning the possible delay. First mail was sent March 7th. Reminder on the 8th and 10th (but that one was in the weekend ).
After listening to Ronan Mc Laughlin interviewing JP Ballard (Swiss Side) on the Performance Process Podcast, I concluded that the 5060 front is too wide and hindering aerodynamic performance and decided to go with the 5055, which has 29mm external width front and back

https://www.youtube.com/watch?v=AtYSsKM7c5E <-- As promised, here's the test of the CRW CS wheel running a GP5000s TR at 0psi. 70kg of load, running at 30kph, and then some light cornering thrown in too. Again, don't recommend you try descend the whole of Alp D'Huez with 0 psi, but, you're gonna be able to stop safely.
