Float up that hill with a bike lighter than air.
Well, it’s not quite lighter than air, but Ridley knows how to improve upon perfection as is evidenced with the Helium SL Road Frameset. This frame is an even lighter version of the venerable Helium — with the same ride quality, sans extra weight.
The SL weighs in at roughly 750 grams, without the fork. This was accomplished through the use of three different carbon fibers. The SL uses 30, 40, and 60-ton high-modulus carbon fiber. The numeric designation is the amount of tons of pressure per square millimeter that the carbon is able to withstand. By increasing the modulus of the carbon, Ridley is able to use less material. Less material equals less weight.
In addition to using higher modulus carbon fiber, Ridley fashioned the front triangle from a monocoque mold. By laying fibers in a mold and then using resin to secure them, one piece is created as opposed to several that need to be joined together. By eliminating joints, less carbon and resin are needed. And while the seatstays, chainstays, and dropouts are still bonded to the frame, the weight savings is significant. A smaller head tube also adds in weight savings.
Not content with a lighter frame design, Ridley also gave the SL a new tube shape. Unlike the Helium, the SL no longer is designed with oversized tubing. Instead, it goes back to a more traditional round tubing that in turn transitions to a more box-shaped tubing as it approaches the head tube and bottom bracket junctures. Additionally the rear triangle also mixes the two shapes. This is a winning combination of stiffness and comfort. The flattened chainstays equate to a stiff platform to optimize power transfer, while the seatstays ensure vertical compliance so you won’t bounce all over the road. Finally, although so many companies are opting for an integrated seatmast, Ridley uses a standard 27.2 seatpost to shave weight and make it easier to pack your frame in virtually any case.

The kit calculator may not show all available options for a custom build and can be a bit tricky in configuring but if we have it on the site we can build it. Often times we have items not listed on the site as well. If you need help in configuring this bike feel free to contact me direct. I'm always happy to oblige!

Hey, Lift my Bike
- Familiarity: I've used it several times
Helium SL: lighter than air, stiff and light.
Yep, that about describes it perfectly.
This is the frame your friends ask over and over again to lift. They know it's light, you know it's light, but everyone gathers around again and again to give it a lift and act surprised yet again. This steed is featherlight at 1050g. Our copy goes into great technical detail on how Ridley has made this frame so light and stiff, but with personal experience with it, I'll just stick to how it actually rides.
This rides like a race frame. Responsive, stiff when heavy power's applied, fast when any acceleration is needed, and nimble but stable when cornering at speed. Even with these characteristics, it it is still incredibly comfortable. Found it very easy on the body on rough roads or long treks in the saddle, and it has a geometry that is not overly aggressive nor perfectly matched for an endurance frame only. It's a frame you could take to your local crit races during the week, and ride for hours on end on the weekends. I felt it was best suited for climbing with ease and descending with finesse, but also found it more than capable at speed on the flats. A very capable all-arounder in my book, a great bike to do it all.

Is there any changes for 2015 other than a coat of paint?
No changes other than cosmetic, same light, stiff, awesome ride.
