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.
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.
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
