I can't find anything remotely close to my old Shimano rim brake tubular wheelset weighing in at 1030g. Anything close in a disc brake tubular wheelset?

Supposedly Schmolke is claiming sub 1kg for their TLO 30 laced to Extralite hubs build. I don't know if I believe that though since Denavelo's TLO30 (rim brake) to Tune Mig/Mag 145 is 1,000g pretty much in the dot and you'd need 4 more spokes on the front and slightly heavier hubs.

Budget? For $630, I'm building a ~1100 gram tubular disc wheelset using Farsports rims, CX Ray spokes, and Bitex hubs. I believe I'd be under 1000 grams using Extralite hubs (-130 grams vs. Bitex), and could go even lower with AX Lightness rims (-100 grams vs. Farsports). But I'm happy with where I'm at for the money spent.

Which model Bitex hubs are you using?

I recently built a pair of 24/28 disc clincher wheels using DT Swiss 240s rear and Hope RS4 front hubs, Light Bicycle RRU25C02 rims, and CX-Ray spokes with DT Squorx nipples. The completed wheels came in at 1430g. On the manufacturer's claimed rim weights, if I'd substituted the tubular version of the same rim (https://www.lightbicycle.com/25mm-deep- ... rface.html), that would have saved 75g per wheel, for a total wheelset weight of 1280g. All up cost of the wheel components was ~$US725, and substituting the tubular rims would have saved $40 on that.

BX106F, 15mm thru and BX106R, 12mm x 142mm, Campy freehub. Both 24 hole. I have another wheelset built using the same hubs in 24/28 drilling and deeper and wider tubular rims.

Roval CLX 32 disc tubular wheelset is 1230- I think that is pretty light for a disc wheelset- They will be robust too. Not flexy or prone to break spokes.
