Sven Nys disc brake bike build Shimano 4
All photos c. Shimano

The debate over discs for cross has long covered the fact that the pros in Europe didn’t want them – well whether he wanted them or not, Sven Nys is making the switch. Shimano recently posted these photos of Nys’ new Colnago Prestige disc being built up for this weekend’s race. Nys will be running Shimano’s new R785 Di2/hydraulic disc brakes with (we’re assuming) a Dura Ace drivetrain.

The wheels that are shown though, we’re not quite sure what they are. Check them out after the break.

The mineral oil based system bleeds in a similar way to their mountain bike brake, while Ice Tech finned radiator pads and the SM RT99 Freeza rotor help keep the heat in check.

Check out that bleed syringe. I want one.

As far as we know Shimano doesn’t have a cyclocross carbon tubular with disc hubs and what appears to be a lack of brake track. Just a one off wheel for Nys or prototype for something in the future?

After this cross season Nys will be saying adieu to Colnago as he heads towards racing for Trek in 2014. We’re not sure what he will be riding when he gets there, but it looks like whatever it is will be disc equipped…


  1. Shimano was smart enough to reuse the XT brakes caliper. I’m amazed he’s mot using the XTR caliper instead to shave a few grams.

  2. Cool…but not sure why the IceTech stuff would be necessary for a pro cross bike. There’s never going to be a heat load consistent to boil the mineral oil. Plus its going to be typically cold weather. But I defer to the engineers…unless its marketing people making the choices.

  3. I suspect the rims are from either ax-lightness’ Full carbon 29er tubular rims for disc brakes or Enve Twenty9 XC disc brake tubulars.

  4. Most importantly…

    What kind of bleed kit/syringe is that?! That is some pro level toolery right there!

    I want that more than the d*mn brakes.

    My vote is those are ENVE tubular XC hoops, the finish looks very similar.

  5. xtr standard hubs on some dura ace wheelsystem carbon rims. except that the freehub looks like it’s steel instead of ti, but it could be a photo illusion.

  6. Agree with Duh – Those are the new Bontrager prototypes. The other rumor is that, since Nys and Shimano are BFF, for 2014, SRAM is out and Shimano is in on Trek. This goes for KfC too, apparently. So anyway, makes sense that Shimano would have some custom stuff with his Bontrager rims to use all the way through Worlds.

  7. “We’re not sure what he will be riding when he gets there…”

    Well, gee, they intro’d the CrossRip (disc) and dropped the Ion for the Crockett (disc); I wonder if there’s another CX bike in their line-up that maybe didn’t get a disc update this year… Oh, wait! The Cronus CX!

    Hire Nys –> intro Cronus CX Disc. No-brainer.

  8. Those are the new 29″/cycloross carbon tubby wheels, intermediate tire base to prevent the need for two different rims, yet still compatible with tufo, Dugast and the likes for both Mtb Tubbies and Cross tubbies.

    I say well done shimano!

  9. Lars Van Der Haar got the disc brake thing moving. After winning the first World Cup race at Valkenburg-Holland (on disc brakes) everyone woke up and wanted to test them too. Unfortunately, there wasn’t much equipment available so as of today (11/11) Sven Nys and Niels Albert each have one bike equiped with discbrakes. This weekend has seen two mudcrosses (Hamme-Zogge and Niel) so discbrakes weren’t a great advantage, also due to their heavier weight.
