Stan's NoTubes Re-Invents the Clincher Mountain Bike Rim

Stan s Notubes Hugo 52 rim-2015

Meet Hugo 52, you may be seeing a lot of him in the future. And if not, he will have inspired us to look at rim design in a whole different way. - Stan's NoTubes photo

The most important product I saw at Dealer Camp in Park City, Utah, was an aluminum rim. Stan's NoTubes was trying to solve the problem of mounting huge tubeless tires to fat bike wheels and in doing so, invented a totally new rim design. The Hugo 52 rim separates the tire beads between a tubular central structure in the rim which carries all the major bending and torsional loads forces. The tire beads are mounted on tiny low-flange wings that extend from either side of the tubular structure. Hugo 52 rims and wheels are designed for mid-sized "Plus" fat bikes, but the ramifications of the design are certain to cross over to all clincher-type wheels.

Stan s Notubes Hugo 52 rim-2015

A cross-section of the 52-millimeter-wide Hugo rim shows the tubular core, flanked by lowered bead wells for each side of the tire and the bead locks which capture the tire against the rim's flanges. The tire is installed by slipping it over the outside of the entire rim, and then popping each bead into the Hugo rim in the conventional way.

The raised central tube and the rim flanges are designed at the same height, so if the tire is flattened against the rim by an impact, the force of the blow is distributed across a wide area. Theoretically, that will reduce or nearly eliminate pinch flats and carcass bruises. The fact that each tire bead has its own "rim well" allows the beads to sit exactly where they need to be to air up without trouble. Finally, the locking section that is built into the rim flanges retains the tire should it go flat. To further stabilize a flat or low tire, the center of the tread is supported by the raised rectangular spine in the center of the rim. While the Hugo 52 rim is far from a fully developed concept, it could be the most important development for the bicycle wheel for the past 100 years.

Stan's NoTubes designed the Hugo 52 rims radical profile to solve the difficulty of mounting up fat bike tires in tubeless configuration. The width of conventional fat bike rims allows the jumbo-sized tires to flop around the well in the center of the rim and prevents the beads from spreading out towards its raised edges, where the beads can begin to seal. The Hugo rim's central rectangular tube naturally spreads the beads apart and forces them to remain in an optimal position for inflation. Once the tire is inflated, the beads are fixed in place by locking ridges. Spoke holes in the rectangular section can easily be sealed with Stan's standard-width tape, and its shape helps to direct sealing fluid to the tire's sidewalls and tread crown.

Bead-seating ridges, in combination with wider flange spacing and the rim's raised rectangular spine, all work together to keep the tire on the wheel should it go flat or soft. If a bead is forced off of its locking ridge, it will be guided by the central spine to remain in place, which should greatly stabilize the tire and help to keep it on the rim, instead of wadding up in the frame or fork. Finally, the raised center section can be exploited to support the center tread area of the tire when a flat occurs in the same manner that the inner liner of a run-flat automobile tire does.

Niner ROS Plus with Stan s Notubes Hugo 52 rim-2015

Niner's latest steel hardtail, the ROS-Plus, is based upon the 29-Plus rim and tire combination that the Stan's Hugo 52 was designed for. The mid-sized tire rolls faster on hardpack and pavement, while approaching the cross-terrain capabilities of the more massive fat bike.

Because the spoke holes penetrate the raised, tubular section, the Hugo 52 rim can be easily sealed with a single wrap of tape, used for conventional-width rims. On the bike, the Hugo 52 rim looks deceptively thin, because its support structure is internal. There is no missing the fact that the Hugo wheel is a radically different concept when you see it mounted up to a tire. At present, Stan's NoTubes has no immediate plans to scale the Hugo 52 down for conventional-width tires, but the future applications are definitely being discussed. I believe that the first step for the Hugo design would be a downhill racing wheel. Aaron Gwin's manly, but heartbreaking ride down the mountain on a bare wheel was, in my opinion, yet another display of how foolishly inadequate the present clincher tire and rim interface is for DH competition - or for any type of off-road cycling, for that matter. Meanwhile, the mountain bike industry continues to feed and breathe life into a dead body while its children are starving for a real solution. The good news is that Stan's apparently has invented one. - RC

  • 13 1
 I know! I used to hunt for the widest bars I could find back around 2000. I couldn't understand why no one offered very wide bars. While I was running the widest t-rex bars I could find, I had massively wide "Double-Wide" rims on my bike. It blows my mind that some of these technologies have been in our faces for years, and no one realized the potential. Or maybe it just takes SRAM to market a technology to us as "ground breaking" before it is widely accepted. (I realize this rim is by STAN's, but SRAM seems to be the proverbial gorilla-in-the-room)

 Don't you mean what's all around comes around Ricky?
  • 7 2
 @ Marzocchi-USA : I think you're missing the point slightly. The design of this rim is to help facilitate tubeless set-up on fat bikes. As stated in the article, it is due to the nature of fat bike tires and how they don't fit tightly enough for the bead to seat while inflating. This rim is not another conventional wide rim. Look at the cross section and tell me of any other rim that is designed this way. Looking at a cross section of a Double Wide, you'll see it is much more conventional in nature when compared to the Hugo. It would be nice to see Marzocchi develop a radical new fork or shock instead of just slightly improving on the tried an trued designs of what is currently available... oh wait isn't that the way all products evolve, one step at a time? Just sayin'

 A nice design but really not that significant. Pinch flats aren't a problem with tubeless. These aren't proven yet either. Hell, this design isn't even new.

I'd be more impressed with tubeless that mounts easy, doesn't require rim tape, never burps and airs up with a hand pump.

Most significant wheel development in 100 years? Not even close. But hyperbole does make for a great article!

 @dfilter on a tubeless system if you deny the rim game over your seal is gone. With this rim you would have to dent it more than the convetional rim to brake the seal, because the place it is sealing to is much lower than the dobbel wall center. If you wanted to break the seal you could make it happen but it would be much more difficult.

 " it could be the most important development for the bicycle wheel for the past 100 years." Ehmm a certain Toby Henderson had this idea some years ago: www.cambriabike.com/T-H-E-Eliminator-Mountain-Bike-Rim-Silver-Black-26in-X-32H.asp
  • 6 1
 Toby and I are friends, His run-flat/anti pinch-flat rims were way ahead of their time - provided that you could manage to mount a tire to them. Off road motos use an improvement on the concept today with a smaller, inflated tire inside the rim. The Stan's version solves different issues, like separating the bead wells, making tubeless installation super easy, and securing the tire when it loses air. Add the potential of pinch-flat protection and it starts to look like a good idea.

 Pinch flat protection for tubeless tyres would be nice. A couple of weeks ago I didn't hop a water-bar (fancy Scottish drainage ditch to help slow erosion) properly and smacked my tubeless back wheel so hard I pinch flatted. I'd managed to punch a hole through the side-wall right down by the rim. Well done, me.

 LOL @ T.H.E. Eliminator Rim; Pretty sure I would have to run at least 50 PSI in a tire with that rim if I didn't want to hit rim every 1/2 a second on anything but a perfectly groomed trail. Tire deformation is pretty significant when running pressures in the high 20's and even low 30's on the average offroad trail with rocks and roots.

 Reminds me of how Moto GP has evolved (mainly thanks to Kenny Roberts). Back in the 80's tires wouldn't hold up to 2 wheel drifts, frames would flex...consequently, tires and frames got much better. Now motors are so powerful, back to tires and frames! The evolution (and similarites to mtb) is fascinating.

 So is a reason why someone couldn't use this with a current high volume tire? Or is it fat bike specific? Would a standard 2.3 tire just get too spread out on this rim?

 I was wondering if this is a wide rim for the masses at first and I admit I am curious. Would this hold up top Enduro abuse? Seems unlikely since fat bikes usually get gentler treatment. Still, I'd like to see.

 Alexsin: ^^^ Not in its present form, but the design shows a lot of promise. New concepts are rarely born fully developed. This one is certainly in its infancy, but if modified, the concept is scalable down to 2.35 or 2.4 inch tires - even for road tubeless - but it will take some time and development to sqeeze out World Cup performance, for sure. The point of this piece is to present the possibility that a completely different take on the clincher rim may get us closer to the day when tires don't fall off the rims mid-way down a four-minute DH run. Or in an XC race, can compete with glued-on tubular tires that stay on the wheels so racers can ride at pace to the technical assistance pits. Right now, wheels and tires are the weak link - ask Pro wrenches. We can do better.

 You could try, but it would give your tire an extremely square profile which would make cornering more difficult. I know a shredder who sold his 40mm ID rims which he mounted a 2.5" tire tofor this reason, these are even wider. Ride what you can shred with.

 Lots of interesting innovation in rims and tires right now!
  • 2 1
 I don't think wide rims are going to make it in the dh or enduro race worlds. It has been tried in the past (mavic's 729s come to my mind) yet people quickly went on the thinner 823s. Wider does mean better traction in some cases, but at the extent of massive drag on pedally bits and absolutely overkill rigidity (I'm talking about all those 35+ carbon rims there). People often speak how stiff their bike/wheels are, while it can actually be worse than having some flex. Ask commencal why they added flex on their Supreme v3 frame on 2 occasions ^^

Mavic designed their xmax enduro rims pretty thin, at the request of their riders. Wider front rim, more grip, thinner rear wheel for less rolling resistance (as the tyre is rounder)

I've got a 35mm set of wheels from velocity, and I find them a tad too stiff. And tyres are just way too big when mounted on them.... Had to try them out though :-)
  • 4 0
 I disagree with you Ploutre. The reason racers went back to thinner rims back in the day was weight! That is why the current deemax ultimate are 27mm (XC width) and not 36mm. Now with carbon rims you can run wider rims without the weight penalty. I run a 35mm velocity blunt front (light and wide for an aluminium rim) and my front magic mary doesn't squirm in hard cornering. At the back I run a heavier but stronger Mavic 729. I think that when tires start getting redesigned for these new and better wider rims drag and square profile tires will be a thing of the past.
  • 3 0
 SintraFreeride has it right, narrow rims were used due to weight, not performance. Mavic 729 and larger rims were more popular back in the heyday of freeride hucking. Everyone was bombing natural gnar and hucking to flat from as high their balls would permit. Then flow style DH became popular and people opted for lighter bikes that jump and rail rather than tank and plow. With rim weight coming down, the tradeoff has shifted and wider rims can be used without getting so heavy that weight becomes a major concern.

 Why are so few people talking about rotational weight and moment of inertia when it comes to these heavy ultra wide rims? The alu hooped versions are especially HEFTY - lots in the 450g+ range (carbon have their own set of issues). Some of these rims are easily into the 550g range yet are being touted as trailbike rims? WTF?

Add a set of lunker rims to your big wheel bike and about the only thing it does well is go in a straight line - forget about ripping tight and nimble single track. Are people that into going just going straight these days?
  • 10 0
 You should read RC's article on wide rims. The reason the weight penalty is okay is that running a wider rim allows a rider to use a lower-volume tire than they otherwise would while still having the same contact patch, and also having the additional benefit of a better-stabilized tire. In other words, running a rim that's 30% wider and heavier (say from 440g to 570g) will result in a net loss of rotational weight, since the rider can go from a larger, heavier tire to a smaller, lighter one while keeping his contact patch the same. The basic point is that the rim forms a relatively small percentage of the rotational weight of the wheel, so it's worth making it heavier in order to make the tire and tube (which are at a greater radial distance from the axis and hence experience a greater polar moment of inertia) lighter. Obviously this only makes sense within a given class of tire sizes - fat bike wheels are always going to be heavier and spin up slower than conventional wheels. But for a given contact patch size, you can make a wheel lighter by widening the rim and shrinking the tire.
  • 2 1
 I doubt people rolling fat bikes care much about reducing their wheels moment of inertia to rip nimble singletrack lol. In fact I think of fat bikes as tanks that chug along to just mess around on, not too performance oriented

 If someone was looking for more air volume for their tire, likely a big reason why they would look into wider tires and rims in the first place, wouldn't this rim design compromise that? That center channel seems to act as a volume reducer, compared to common fatbike single wall rim designs.

Also, is more air volume actually a good thing for a large % of riders? Wouldn't it work like air shocks, where the "spring rate" become less progressive as there's more air volume in the spring? I guess the riders that like less progressive air spring rates (ex. higher volume air cans, or fewer air spring spacers/bottomless tokens) would be more into this stuff.
  • 2 0
 I was thinking along these lines too, but conversely, I was thinking that reducing the air volume of the tyre will create a 'rising rate' spring, so it would be harder to bottom out. As the tyre compresses, the pressure will increase drastically, maybe supporting the tyre wall and resisting pinch flats... which could be great. But it might be less beneficial for traction as the tyre might not mould to the terrain as well. Who knows, it's all speculation.
  • 1 0
 I like that thought, never really came to me. A more progressive tire "spring" could be another way to drop the pinch flat rate, which I'd absolutely love Smile But I'm not too sure it'll be significant, considering the size of the compressed area on impact vs. the whole air chamber inside a tire.
  • 1 0
 Agreed, you're probably not increasing the pressure enough. I certainly don't notice a difference between a 2.5 and a 2.1.
  • 2 0
 didn't there used to be a product that was basically a thick rubber strip that sat in the rim well and protruded higher than the sidewalls to reduce snakebites, back in the nineties?

Don't know what happened to it seemed like a reasonable idea, probably a bit heavy though. Much like the moto & schwalbe tube in a tube idea, not inflateable but could be retrofitted to any rim?
  • 3 0
 With such a short vertical profile I see flat spots and bent bead lips with more extreme riding. Probably cool for Fat bikes tho.
  • 5 0
 I think you are correct Skid, that it may not be impact resistant enough at present, but the tubular profile is what gives the rim stiffness and it has plenty of room to grow.
  • 1 0
 They should flip the inner wall from concave to convex. They would get a wider cross section (more rigid) and slightly improved impact area (further reducing pinch flats and rim dings) without adding a single gram of material.
  • 3 2
 Stans of all companies seriously need to invest in a non-drilled internal rim bed, like mavic and easton have, this is truly the only way to go with tubeless, no hodge-bodge rim tape sealant crapola... and surely if that internal section was flat it would do better against pinch flats?

 Yes it can be a pain retaping Stans rims.But.......it keeps costs down.Proprietary spoke/nipple systems can add cost.Also some use large strong spokes.

 If I have a fat bike and am pedaling around in the backcountry of Montana in the dead of winter (operative term being dead) the last thing I'd be concerned about would be going tubeless.

 good to see designs for offroad rather than trying to adapt an inadequate system from a road bike but i bet they drill th rim for presta valves. one step forward and one step back

 Wasn't Hugo the name of a Category 4 hurricane that made landfall on South Carolina in the 80's? Hope these make a real impact on the fat bike and wheel market.
