2013 Deda Elementi Intertial road bike wheels with offset brake track

Deda Elementi’s 2013 range has some interesting parts, none more so than the new Inertial wheels.

The design is called a “Reverse Inertia” system and basically takes the laws of rotational mass and makes them work in favor of the cyclist. Some of the tricks are fairly common, like putting the spoke nipples at the hub rather than the rim. What’s new is the dropped brake track, as seen above. It’s only a few millimeters down from the rim’s edge, but the combination reportedly moves 36.1g of mass away from the outermost part of the rim. Every bit helps, I suppose.

For those worried about carbon brake tracks heating up and delaminating or exploding under the pressure of a clincher tire, Deda’s got you covered there, too. First, the brake track is pretty much completely below the bead hook wall, and that wall is quite thick. Second, their resin and fiber mix has been tested to almost 200ºC (392ºF) with 30 minutes of continuous braking without failure.

More details, plus an expanding range of 35mm bore handlebars and stems for road and mountain bikes and aero, pista and fixie stuff after the break…

The hub shells get a decent amount of machining and hold all nipples. At the rim, the spokes’ rounded head sits inside a curved shape to let it angle directly toward the hub with no bending stresses.

Two wheels will be offered with these rims, the WD45CCL and WD30CCL, both clinchers. The 45 has 45mm deep rims and the 30 has 30mm deep rims and comes with offset brake shoe holders to help get the pads low enough. Both have two slightly thinner, lighter spokes adjacent to the valve stem to balance the added weight. Claimed weights are 1460g and 1380g respectively (without skewers).

Across the range, the carbon tubulars and alloy clinchers all get the new hubs with spoke nipples at the center, but only the top two clinchers use the offset brake track.

2013 Deda Elementi 35mm handlebars and stems for road and mountain bikes

Deda’s Trentacinque (35) series of handlebars adds mountain bike riser bar and stem options. The Condor (center) is a UD carbon riser that’s an impressive 750mm wide, has minimal rise and comes in at just 170g.

On the bottom row is the XDR, and alloy riser for more aggressive riding. Also 750mm wide and also 170g claimed weight.

2013 Deda Elementi Reverso 35mm alloy mountain bike stem

The Reverso 35mm stem has an 18º angle and comes in 60 or 80mm lengths. Claimed weight is 142g. Not shown is the Box 35, a stubby, machined zero-degree rise 45mm long stem for freeride bikes

2013 Deda Elementi Superleggera 35mm handlebars and stems

At the top of the range, the new Superleggera handlebars and stems set a pretty good target for weight weenies. Available in standard OS 31.8 and 35mm bore, they get a new 40T UD carbon build to come in at just 180g (42cm – 44 and 46 also available). The 35 bars carry the oversized clamping section all the way to the bend.

The Superleggera stem is a 3D forged 7050 alloy that claims to be the lightest production stem at just 99g for a 110mm. It’s only available with an 18º angle but comes in a huge range of lengths: 80-90-100-110-120-130-140.

2013 Deda Elementi Carbon Blast aero bar extensions

If last year’s Bandito wasn’t eyecatching enough, there’s the new Carbon Blast aero extensions. We all know how nervous roadies get when someone shows up at the group ride with full on aerobars. And, truthfully, they’re not all the comfortable for base miles and winter training. These let you clip on a little free speed when circumstances warrant without freaking everyone else out or forcing yourself into a tuck on every ride. They’re 135mm long with a 34mm rise from bar center to front center when mounted level. Width is fixed at 90mm with the ITU-required front bridge installed. Weight is 226g.

2013 Deda Elementi pista and oversized fixie bike and urban handlebars

The new Pista (black) and Velocita (chrome) bars have a traditional track bar shape. The Pista is the more performance oriented model being made of double butted 6061 T6 alloy and coming in at 279g (42cm only). The Velocita is for style. It’s full chromoly steel and fully chrome plated. Weight is 676g, available in 42 and 44 widths (outside to outside).

On the right, the Street Issimo bars are aimed squarely at the fixie riding hipsters. They’re just 460mm wide and come in at 190g. There’s a tiny flat bar, too, called the Dritto 26 that’s 500mm wide. The stem is the Cortissimo and has zero rise and just 45mm length. Weight is 148g.

Note the wide variety of handle bar tape colors in the background, too.

2013 Deda Elementi seatposts

The new RSX seatposts (left and right, colors) use a two-bolt clamp. The RSX02 has a slightly lighter (285g), one-piece 3D deep forged post from 2014 alloy. Only available in 31.6 diameter and 350mm length.

The RSX01 is made of 6061 alloy and has a bonded head. Weight is 295g, available in 31.6mm and 27.2mm diameters and 350 and 400mm lengths.

The RS01 is the chromed 6061 alloy model you see at far right. It’s 3D deep forged, available in 31.6mm and 27.2mm diameters and 350 and 400mm lengths. Weight is 333g. All three posts have a 21mm setback.


  1. This is the first time I’ve heard of a 35mm handlebar standard. I know it’s futile, but I am begging the rest of the bike industry to please not jump on this bandwagon. Pretty please? Oh to heck with it… let’s just make every part of every bike incompatible with all the other bikes out there. I expect to see a 33mm handlebar diameter next week…

  2. @James S Deda has been pushing this 35 “standard” for about 2 years now, and I have yet to see it spec’d on any bike, nor have I seen one in the wild.

    HOWEVER, I would imagine there are two types of aftermarket buyers: bargain shoppers and performance shoppers. The bargain crowd isn’t going to go buy a $100 stem, but if a performance shopper is convinced by the argument, they are probably willing to buy it (and no self respecting roadie would have a bar and not the matching stem).

  3. I saw a chick with it on her Cross bike (35mm bars and stem)

    She said the durability of a wider diameter makes her feel more confident beating the hell out of her bike, and throwing her weight on the handlebars when remounting.

    Whatever works, no?

  4. Tthe standard is somewhat new, but it’s been at shows for quite a while, and on the market for something like a year. Deda and Easton are the only ones thus far I think. I don’t think it’s as much of a “bandwagon” as it is a market offering for those who want the benefits of a Ø35mm interface – higher stiffness at lower weights. For a sprinter or a DH racer, it makes total sense. Perhaps the day will come when more bikes than not have 35mm bars and stems, but it’ll be a while from now. I’d say the variety of rear wheel axle widths, types of headtube, and front derailleur mounting standards are far more alarming than the incursion of a new HB/stem clamp standard.

  5. I’m curious to know if the “cyclocross chick” has ever broken her handlebars or seen anyone else break theirs. And by the way, in order for a 35mm diameter bar to be stiffer at lower weight, it also has to be thinner walled. Which means that the bar will be easier to dent and more susceptible to damage from point loads. It just doesn’t seem like the marginal benefit would be worth introducing yet another standard.

  6. “Easier to dent and more susceptible to damage” is relative, while stiffer because of increased diameter is objective. This sizing is a differentiator, and may be useful in DH and Track applications. Remember Oval outfitting teams with 26.8mm bars and stems well after everyone had been riding 31.8mm for several years- they claimed it was for aerodynamics- more realistically it was just a way for them to differentiate.

    I’m all for options, and lighter and stiffer are options I like. I doubt Deda would introduce a new bar/stem and not reinforce areas that see point load stress- FEA was no doubt in use or we’d see weight gains (which I believe were aparrant in the fist generation of M35 components) vs. 31.8mm models.

    Last years design looked like they just increase size but increase weight and frontal area with it- which didnt really catch on. This year they’ve come back and finessed the design with a lighter carbon cloth/resin and possibly removed some uneeded material, resulting in lighter and stiffer bars and interfaces. If they’d make a pista version i’d try it out next track season…

  7. i have a mountain bike i want to put easton 35’s on. This is a good new option for those that put air under tires at every chance. 31’s flex some in carbon and aluminum has no dampening. i cant believe all the haters on this site.

  8. “There is no advantage to the 35mm bar until you get to 780mm widths and at that point only the fatigue life is better, but the stiffness claims are overblown. 31.8 bars can be built very stiff. Stiffness has to be tempered with flex or you will just knock your fillings out!” – Sited from: http://bikethomson.com/overdrive-stems

  9. I spied Andre Greipel running Deda 35mm bars and stem at the Tour of Flanders and Schelderprijs earlier this year. They went nicely with the gorilla paint scheme on his Ridley Noah. He’s one big unit that can churn out some serious power in a sprint, so probably justified on his rig.

  10. Why does everyone need stiffer bars? I have bikes with 26.4mm (in titanium and aluminium) and 31.8mm (in carbon and aluminium) and there’s no way I could tell the difference unless I really looked for it. Does it affect my riding in any way? Not in the slightest. Have I seen anyone break bars? Only after they’ve been damaged previously, check you bike, it’s common sense.
    What’s this rubbish about rotational mass too? Again, the difference would be minuscule, so small you wouldn’t even notice. Even if you race how many types of racing involve starting and stopping so much that it would make even a seconds difference? Cross maybe buy there’s so many other bigger factors.
    I’d hoped the internet would lead to more informed consumers which would stop the bike industry pushing all this bull on us but it still keeps getting rolled out and people are still buying the snake oil.

  11. @brandon, I like how you referance Thomson as if they are an expert in handel bar having just got into the market a few months ago with hohum product.

  12. it may, in fact, be easier to dent. it’s also likely more susceptible to buckling. but i dont know these bars’ actual wall thicknesses.
    the general engineering rule for tubing to resist buckling, denting, etc., is the wall thickness should be greater than 1/50th its diameter. so if these bars have a wall thickness at or less than 0.7mm (probably getting close in certain areas), then they have something to worry about. if not, theyre likely fine.

  13. Personally, I’d like to give the 35s a try just to see how they feel underhand. If they are keeping the diameter at 35 all the way until where the shifter clamp area is, it should feel a little better under my wide hands.

  14. i was wondering if all those who commented on how bad the 35’s has tried the handlebars ? 😀 or is it just some people who is uncomfortable on trying out new things ? *whoever heard bicycle needs Di2 & EPS years ago ?*

What do you think?
