Xtr tub wheels are available cheap (£600).

Can anyone see any reason these wouldnt work as a road wheel? At 1300g they are plenty light, lovely hubs and no wider than new school road wheels. I have a got a gt grade carbon, the stock wheels are nice and wide, so i was going to set them up as off road tyres, then get a nice set of tubs for road work.

I’m looking for a decent set of disc tubular wheels (I like tubs on road) so any other suggestions welcome, but 15mm axle front, 135 rear and discs pretty much throw any value out the window.

Could be talking out my arse but Xtr are presumably for tubeless tyres not tubs & also won’t work with road tyre pressures?

They do a tubular which i assume is for posh xc bikes.

They’re designed for wider tyres, but as you identify road wheels have got wider anyway, albeit often not so much at the rim bed. No reason it shouldn’t work.

Should be ok, but personally wouldn’t run thinner than a 28c tubular on it. Something like a Pave would be good.

isn’t mtb 11 speed different to road 11 speed ?

I’ve just stuck road tubs on my CX rims (19mm internal width), and had initially thought I’d be restricted to big tyres, like 32s. From researching it, though, this is not the case and you have a lot of lattitude with matching sizes between tubs and rims because obv there’s no critical tyre interface at the edge of the rim. So a set of pave 27s fit great and I could have gone smaller.

Those xtr wheels do indeed look like a fantastic price – 26 mm wide sounds a bit on the wide side [are modern road rims really that wide?] but I think would be fine given the choice of tyres available.

I’ve been thinking of going the other way and getting a set of tubs for mountain biking – need the focus to widen a little bit from race-only though [ie light but not ultra-light, tyres a bit more robust].

11 speed road freehubs are wider, you’ll be stuck to using 10 speed cassettes.

So i’d have to use mtb 11 speed casette. My grade is a 105 groupset.

If its a no-go, any recommendations on something suitable?

Just looking for a light disc tubular that i can put 25’s-28’s on for road work.

Yes. But then you’d have issues with mech capacity.

Or you can machine 0.2mm off the back of the cassette and it would fit. Other options would be Chinese rims laced to hubs of your choice.

Best place for chinese rims direct?

FarSports have the best choice. Love my 38mm clinchers.

Ordered some 23mm farsports 38mm cyclocross tubulars – should do the job!
