I have a set of PCW's with 180 hubs (disc) and the rear spins very smoothly as one would expect but the front rotates is much tighter. With less than 500 miles on them something seams to be off. With the 180's being pretty simple and no preload, are there any adjustments I can try to make using normal tools (I do not have DT Swiss specific tools) that I can try to loosen things up?
While unlikely, it is possible bearings where improperly installed causing deformation to the bearing races which would induce additional drag on the bearings as evidenced by how rapidly the wheel spins to a stop without load. Might I suggest removing the end caps and manually turning the front bearings with your finger tip to see if there is any notchiness or binding?

Did you ever get this sorted, and if so what was the issue? I am waiting on a set of 6560s with 180 exps, hope it's a one-off.

I had an issue with a brand new wheelset with 350 hubs; the front slowed down and stopped quite abruptly when I spun it. Took it back to the wheel builder who eventually removed the bearings. Turned out there was a small bit of plastic behind the bearing which apparently caused a slight misalignment. Hub shell cleaned, bearing installed, spun perfectly.

I left my second wheelset with 180 exp hubs to my wheel mechanic today. It was not as worse as the first set, but these have only done around 1500km max and the other +11 000.
End caps are anything but smooth if you hold the end caps tightly in your hand and spin the wheel you can feel enormous drag. Once installed on the bike it spins a lot better.
He then showed me a set of ZTTO hubs supposed to be identical to DT Swiss 240 hubs and that was spinning insanely smooth. Never felt anything like it. ZTTO hubs that cost $90 he said.

Yeah but spin under no load is not very indicative of performance of spin under load, otherwise OSPWs would save millions of watts, lol. I feel like with DT Swiss you usually get that for which you pay.eucalyptus wrote: ↑Thu Nov 10, 2022 9:12 pmI left my second wheelset with 180 exp hubs to my wheel mechanic today.

Did you leave them for the freehub issue? My understanding was that only first generation 180s had the freehub issue and that later runs had the new part already installed. Specifically if the batch number has a 1 or higher for the middle digit it has the new part but if it was a 0 it needed to have the part replaced. Or are you having other problems?

DT hubs are a bit different. I have a rear DT350 that feels tight to spin with the fingers, but spins nicely if I tighten the rear through-axle right up to spec. It's been discussed before, the design requires a certain sideload to spin relatively freely.

Thanks, read the same thing the other day. Maybe it was you too haha
Then I can sleep tonight without nightmares. I trust my wheel mechanic but this time maybe he is wrong
I've 3 set of wheelset, 2 set with latest D180 EXP mfgr mid 2022 and 1 set that's 2020 mfgr, All 3 wheelset spin freely underload. I noted the recently latest 2 wheelset that I purchased August/Sept 2022 with recent mfgr date was tight when I try to spin the wheel without load. but after 500-1000km, the wheelset is spinning freely(under load) like any other wheelset, example as good as in comparison to my 2022 Dura Ace C50 wheelset and PCW/CK.....
