Ordered two wheelsets (road & gravel) from Peter yesterday, lead time estimate was 10-12 days. Communication was superb! Cant wait to ride them.

As if I already don't have a backlog of gravel wheels to feature, Peter goes and drops these LoL

For my TanTan GR201 gravel frame folks...these will be the meta wheel.

I don't like these super wide gravel rims. All you do is expose the rim to damage from rocks and such. It doesn't even do anything for aero because the edge of the rim is where airflow coming off an off-road tyre is absolutely demolished. If you're gonna make a wide rim, it's better to do it like DT Swiss (Swiss side) and Parcours, where the rim edge is relatively narrow, and then the rim bulges out closer to the middle. Safer and more aero.

Depending on price and weight these will certainly be my next set of gravel wheels. Have been eyeballing the Nextie SGV, but have been not ordered since i emailed Peter about these a while ago, so i did know they were on track for this season. Hopefully they will match Nextie weight wise, and as usually have great price like xmcarbonspeed usually does.
I would say there is no problem at all with damaged sidewalls if you go >45mm width, and these are also hooked compared to 303 XPLR. I think smaller width will also work fine - but tire manufacturers have to design the tires for these kind of rims for that. (Smaller tire casing width lay flat, but wider contact patch - if 40mm should measure 40mm that is) I would even think it may introduce lighter tires for same width because of that.

If you want to protect the rim edge with the tire, then the tire needs to be wider than the rim at the rim edge. Now your tire+rim has an hourglass shape. So air flow can  separate at the tire. And the space between the widest point of the tire and widest point of the rim becomes a void air must fill and will increase drag

Reason those new Goodyear XPLR tires have been a failure in tandem with Zipp's XPLR gravel wheels is simply because the tires aren't wide enough. Way too many side cuts since the side walls are exposed. This is according to conversations I've had with Sram/Zipp employees, and I'm certain Sram won't admit this publicly.

40/45c tires on a (HOOKLESS) 40mm external, 32mm internal wheel for gravel is asking for trouble. It doesn't even follow the ETRTO standards. Although I don't ever follow this myself LoL

A 32mm internal wheel "should" be using a 58 - 65c tire. But yeah no is gonna do that. For Peter's new gravel wheels I would not run anything smaller than a 2.0 MTB. Better hope ya gravel frame can clear that.

I urged Peter to design a new Gravel frameset next with at least 700x57 tyre clearance with at least 46T chainring.

Does anyone know if XMC is already offering an integrated handlebar? Last time I heard about it it was on their plans

[Pistonbroke]

Out of interest, what is the lightest set of wheels xmcs can do?
I watched pandapodium the other day on YouTube at the bike show saying they would be selling a 900g ish wheelset soon.

ETA been using the d40/33 t1100 as gravel bike wheels for the last five months and they've been brilliant, thanks Peter!
