    No Compromises Between Weight and Efficiency

    Lighter is better right? Yes and no. Yes, it is better if it can transfer your power efficiently to the road. No, if all that effort you take trying to move the bike forward simply goes up in flexing the frame back and forth. The Helium range is a non-compromising solution for the rider who demands the lightest weight from his bicycle yet still wants the bike to stay stiff and resilient under his feet. At fewer than 750 grams (in size M), the Helium SL is still stiff enough to take all the stomping our sprinting ace, André Greipel, has to offer, yet light enough to float over the highest mountain passes with ease.
