Yes, we do have light weight MTB wheelset. And that combo wheelset would be $850/pair without promotion.

The weights are so light - I do worry that we're suffering Keith bontragers proclamation about light cheap and strong.

Loads of exploding farsports rims hitting normal potholes and bumpy road riding or gravel riding - xmc confident their rims are stronger? T1100.is very stiff and light but not very flexible / resilient


Or do they think that was because of overtensioned carbon spokes?

Like I say to most guys who order gravel wheels, we suggest them taking T800 rims, even T700 version for gravel use if they are heavy. T1100 version is more suitable for road use. It's obvious you can't keep lightweight, strong, cheap on same rim for all kinds of use. Just like you can't do lightweight wide XC MTB rims for AM or Enduro use.

Since the spoke tension on carbon spokes is much higher than regular stainless spokes, to make sure stable quality, we don't make these hubs extremely light like someone else do, our new 20/20H straight through version hubs weigh around 290g

Is it possible to get the hubs anodised in a custom colour?

Still in the middle of running cfd to decide which rims I go for. XMCS 65 with carbon spokes is a candidate for the rear. Sadly all off the shelf carbon spoke hubs are minimum 20 spokes at the front, so will have to go with steel for that.

Sorry, negative for just single hub to do anodised custom color. Unless we happen to do the exact color anodising as you want, but mostly it won't happen, ours hubs are anodised in black or titanium color.

Got my D50CU-28 T1100 in the Mail. Wheels look great, packaging is very good and overall quality seems to match expectations.

One caveat are the actual rim measurments. Actual measurments are 22mm internal and 29mm external instead of 21.4mm internal, 29,2mm external.
With the wider internal and narrower external width a 28mm gp5000 s tr measures 29mm and sits flush with the rim profile, so no rule of 105% to achieve here, if your don't want to have a 25mm tyre, which most of us certainly will not want. So in some way the rim profile is neither here nor there, neither fit for narrow nor really fit for wide tyres. I will get on with it, but this difference to the advertised measurments is the worst difference you can have in a rim profile. Both rims measure the same btw, so i don't think this is a unit variation problem.

Measurements done with a digital caliper and at multiple locations.

I find complaining about 0.7% difference in measurements quite remarkable.

Also, how confident are you that 0.6 mm narrower rim would give you actual tire width that conforms to the 105% rule?

29mm is the fastest tyre size on rhat rim at low yaw

I received my pair of D50CU-33 T1100 just before Christmas. With CX sapim spokes and inhouse hubs - weight of 1320 g. A bit higher weight because opted for rims without holes and as I learned, it means no carbon spokes available. I also opted for brass nipples. Built with GP5000 TR 30mm, real width 33 mm, and a total weight with ultegra cassette, 2x160mm disc rotors and aliexpress valves - 2440g. Excellent quality, beautiful hubs. Only done about 120 km so far, due to shitty weather and snow here in Switzerland, but really happy with it so far.

Excellent service and support from Peter!

Yeah, those are rounding errors... And why would you complain about wider rims these days :)

But hey, if you can't keep up with the next group ride, you know what the problem is...  ::) It's that 0,001% deviation...
