After the development of the well-received Helium, Ridley's engineers began a new task -- to maintain the stiffness and stability of the proven original, while at the same time reducing its overall weight. The result of their efforts is the stunning Helium SL. Weighing in around 1050 grams with the fork, the Ridley Helium SL rests squarely at the front of the market's low-weight frame offerings. And while most sub-800 gram frames are more akin to wet noodles, the Helium SL is responsive and bred for the racing in the mountains. Ridley just made your choice simple. So, if you're like us before our summer test ride of the Helium SL, you're wondering two things: how is it so light, and what does that weight cost me in ride quality We'll address these in order. Starting with the weight, the SL sees a 150 gram decrease from the last iteration of the Helium. This was achieved through the use of a more sophisticated carbon selection, this time utilizing a strategic placement of 60, 40, and 30 ton high-modulus carbon fiber. Before the SL, the Helium featured a predominately 30 ton carbon composition. Why is this important Well, for a refresher, the 'ton' designation in '60 ton' refers to the carbon's ability to withstand 60 tons of pressure per square millimeter. So, basic logic tells us that a stronger carbon fiber requires less carbon to be used; as is the case with the SL. And on top of the carbon, Ridley bonded the carbon with a nano resin this time around. This further reduced weight, however, it also increased the strength of the construction. Not surprisingly, Ridley wasn't done yet. To further reduce weight, Ridley constructed the front triangle of the SL with a monocoque design. This means that the entire front triangle (head tube, down tube, seat tube, and bottom bracket lug) is made in one piece. How does this save weight Well, with the current SL system, the seatstays, chainstays, and dropouts are bonded to the existing triangle by applying resin and then...
