2017 Alchemy Helios SL

Alchemy has pushed the envelope in carbon fiber production even further with the release of a lighter version of their flagship Helios.

Dubbed the Helios SL, Alchemy uses the same tube profiles and subtle aero shaping as the Helios, but has cut the complete weight of the frame down signicantly. Coming in at a scant 790 grams in a size 54cm, the Helios SL is the perfect bike for climbing while maintaining the stout and snappy feel of the original Helios.

The Helios SL features an aero top tube, rounded seat tube, and a flared shaped down tube to increase torsional rigidity and aid in acceleration. Like the Arion, the Helios SL is designed for superior handling, speed and efficiency

The construction of the Helios is tube to tube, with carbon wrapped junctions. This makes for a strong frame that will last even under the most aggressive riders. The bottom bracket is an oversized PressFit 86 to also increase stiffness in the frame and the cables are routed internally for a neat and tidy look. These are all great features but the main reason people return to Alchemy is their dedication to customization. Their desire for to make each bike their own.

You have the option of having the geometry customized or choosing one of five stock sizes. You also have the option of tuning what Alchemy refers to as the “Ride DNA” of the frame. Each section of the frame is isolated and you can determine how stiff or compliant you want each part of the bike to feel, allowing you total control of the ride frame’s ride quality. This is YOUR bike with no compromises.
