stans notubes grail gravel road bike rims and wheels sneak peek

Last year, as GT was developing their new Grade gravel road bike (more on the bike coming soon), they went to Stan’s NoTubes for a high end, tubeless rim to go on the top models.

The result is the new NoTubes Grail gravel road bike rim. Technically, it’s just a wider, disc-specific road rim, but it’s built durable enough to handle off pavement escapades. Rim profile is wider than their current offerings in that category, namely the Iron Cross, and it can handle a heck of a lot more pressure.

Width is a hair over 20mm internal, and just over 24mm external with a nice rounded profile. They’ll offer it in 24, 28 and 32 hole drillings and as complete wheels in Team and Comp specs. The bead can hold up to about 125psi, making it perfectly capable as a wide road bike rim for things like the Hutchinson Fusion and Sector, etc. Look for more tech details this week, and a few more pics are after the break…

Retail will be $105 for the rim, and Team and Comp wheels are $695 and $645 respectively. Main differences are 24/28 lacing and stainless bearings on Team and 32/32 lacing and standard steel bearings on Comp.


  1. I am in the market for disc cross/gravel/road wheels, what is the eta on these and how do they compare to a set of 29er crests that cost $100 less?

  2. $105 – That’s a price too good to be true? Interestingly, the tire in the pictures is a Continental (which is a company that doesn’t offer a road tubeless tire(s)).

  3. So…….Is Stan’s making this rim to work specifically with Hutchinson UST Road Tubeless tires? If so, that is a major departure from their past product history. If they did not use UST dimensions, then I would be surprised if a Hutchinson UST road tubeless would even fit onto this rim. Non-tubeless tires has always been Stan’s focus, so this is a bit confusing.

  4. These rims are exactly what I’ve been looking for! Finally. Now hopefully some more options for larger road-tubeless gravel/adventure tires will appear.

  5. But will they crack at the spoke holes? and who still uses ust?

    Im interested in the rims… just not sure they are better than the hed belgium c2 plus

  6. Interesting times for those like me who don’t care at all with race bikes, but do commute for working and ride for pleasure. With the forthcoming Diverge from Spesh i plan to change my old TriCross. At last, some practical road bikes, with real brakes (i mean when wet), real tyres ( i mean tubeless), some comfort but with efficiency. Just add an eccentric bottom bracket, a Gates belt drive and a Alfine Shimano and Go!

  7. RC – Crests are 1mm wider internally, and are rated to only 55psi in narrower width tires (down to 1.5 in), but I have 38mm commuter tires on them right now pumped up to 70psi with no problem.

  8. “Crests are 1mm wider internally, and are rated to only 55psi in narrower width tires (down to 1.5 in),…”

    This only applies with tubeless. With tubes higher pressures are fine. I also use Crests for commuting with 38mm tires. I’ve set them up tubeless but don’t really see the value. Going forward I’ll return to tubes for that.

    I also don’t get the point of these when Crests/Arches already exist.

  9. @Mark,

    To my knowledge, Stan has never advocated conversion of non-tubeless road tires to tubeless use. This is the opposite of his stance on MTB tires, so you are 100% correct in regard to the mountain arena, but not road.

    As I recall, he has actually sold road tubeless kits using Hutchinson Road Tubeless tires for use on his Alpha road rims.

    The distinction is due to the higher pressures required on road bikes, which can stretch a standard kevlar bead enough to cause a blowout. This is why Hutchinson uses Carbon beads on the Tubeless model tires. The lower pressures used on MTBs generally don’t cause this problem, so kevlar is fine.

    Having said all of that, I am curious about how oversized the bead seat diameter is on these rims. As you point out, getting a UST tire on a Stan’s MTB rim can be difficult as the rims are oversized in order to get a non tubeless tire to seal adequately. I am curious if he does/does not do this on the road rims since they appear to be intended for true Road Tubeless use.

  10. @craigsJ and others comparing these to existing rims. While you can run higher pressures in your existing stans rims it is a bad idea.
    While the bead might hold, the rim is not intended to hold the pressure and will eventually crack. As a race mechanic for cross teams I’ve seen this quite often.

  11. What’s the saying — strong, cheap, light — pick any two? Um, weight?

    @Brad: the C2 Plus is nice rim but only available in 28 & 32 hole. It’s also 150 bucks.

    @muf: apples/oranges here. The Grail is disc specific; the SL23 is rim brake. I also love the SL23 a little less every time I have to mount tires. I shouldn’t have to throw a tire in the clothes dryer for 5 minutes just so I can get it mounted on an SL23 without breaking tire lever or getting a blood blister.

  12. @bikermark – the SL23’s are available in an all-black finish now for disc use. They actually still have the machined brake track, so you could still use them with rim brakes as well, but the finish will wear off of course.

    re: using the Stan’s MTB rims with tubes and high pressure – I don’t recommend it. I’ve blown tires off rims before with tubes and not that much pressure.

    These look good IMO. Will be interesting to see all the final details.

What do you think?
