It seems bigger is better in the Deda camp these days, as the Italian component makers have introduced a 35mm-diameter handlebar and stem system that’s claimed to offer a 50 percent increase in bending stiffness over their standard 31.7mm offerings.

But isn’t 35mm too big, you say? Perhaps, but not when you consider the finished diameter of a 31.7mm bar when handlebar tape is taken into account and the fact that the new M35 is intended to be unwrapped up top.
Even so, some riders will prefer the additional grip and cushioning of bar tape, and the extra stiffness could prove too punishing for slighter riders or on rough roads. However, this is just the sort of thing that should appeal to sprinters.
In addition, Deda have managed to increase the clamp diameter without adding much of a weight penalty. The Trentacinque stem is only 26g heavier (claimed weight of 136g for a 110mm extension) than a comparable 31.7mm-diameter Presa and Zero100 bar and stem, and the M35 is actually 4g lighter (210g for a 42cm).

Whether or not the new size will gain wide acceptance is another question entirely but if nothing else, it presents another option. Besides, Deda aren’t introducing it as a wholesale replacement for the current oversized standard.
Deda’s Vincente stem concept is even more radical, with a unique internal-external steerer clamp that’s claimed to be gentler on carbon tubes while also being more secure than traditional setups. Separate aluminium clamps and titanium hardware keeps the Vincente pretty light, too, at a claimed weight of just 137g.

Other new component offerings occupy more value-oriented segments of the market and include the RHM01 (round cross-section) and RHM02 (aero cross-section) aluminium road handlebars, the Quattro2 and Zero1 forged aluminium oversized stems, and RS01 and RS02 two-bolt aluminium seatposts.
Frames, too
Sister company Dedacciai’s ever-expanding collection of frames will total nearly a dozen models for 2011. Sitting at the top of the heap is the intriguing Temerario, said to be Dedacciai’s stiffest option with simply massive squared-off carbon fibre tube sections, a tapered 1-1/8 to 1-1/2in front end with similarly enormous fork blades, and unique bonded-in titanium seatstays.
Dedacciai are also among the shrinking minority that continue to favour integrated seatmasts, with the Temerario sporting a deep oval cross-section throughout its length – and naturally, it’s topped with a Deda alloy head. Despite the liberal helpings of surface, claimed weight is still rather impressive at just 1,050g for a medium frame, plus another 330g for the matching fork.

Dedacciai’s second-tier Super Scuro is also a new design, though more an evolution of the existing Scuro RS than a wholesale clean slate like the Temerario. Changes from the RS include a more heavily bolstered tapered front end and bottom bracket area, larger squared-off chainstays, smaller seatstays, and internal cable routing – and again, still with an integrated seatmast. Claimed weight is lighter than the Temerario at just 990g for a medium frame, though the fork is heavier at 420g.
