DEDA M35 Handlebars


Just when the 25.4mm and 26.0mm clamp diameters of yore were fading into obscurity and we were pretty much left with 31.8mm for both mountain and road handlebars, Deda introduces their M35 Handlebar. With its 35mm top section, the M35 is 50% stiffer than a comparable 31.8mm bar.The 35mm diameter extends all the way across the top of the bar to the transitions towards the drops. Those with bigger hands will appreciate the extra surface area. And with the massive increase in stiffness, it comes as no surprise that this would be an ideal handlebar for bigger, more powerful riders. It's also a product of the Deda Rapid Hand Movement (RHM) design initiative. Deda noticed that more and more pro riders have been dropping their bars in relation to their saddle. As a result, it seemed that riders were spending less time in their drops. So, rather than raise the bars, something a rider might be loath to do because he likes the position of the tops for climbing, they shortened both the drop and the reach of the bars. RHM bars are shorter than a traditional shallow drop handlebar. The RHM bend is a wonderful balance between anatomic and traditional round shapes of the past. It uses what Deda calls a Continuous Incremental Radius. This simply means that the length of the radius (or how tight the bend is) changes a number of times through the bend in the drops. What you get is a bend with subtle shaping that offers comfort in multiple positions. The Deda M35 Handlebar is available in Black, Red, and White and in three widths -- 42, 44, and 46cm (measured outside to outside). The drop is 129mm, and the reach is 75mm. Please note that this bar requires the use of a stem with a 35.0mm clamp diameter.

Stiff, stiff and stiff. If you think your front end is a bit flexy these bars with the stem just make the whole front end come under control so well. I felt I had changed forks and gotten a longer heat tube. That good! The recessed holes for internal routing of both shift and brake cables are a nice touch. Not taping the bar much past the hoods works well for me. I like the feel of the unwrapped bar on the tops.


They are probably not the best for riders with small hands and of course stem choice is very limited. Running some thicker types of outer housing through the internal routing is a bit fiddly.
