2018 Argon 18 E-117 Tri PLUS Triathlon/TT Frameset

Available to Order


One of the most popular frames at this year's Ironman World Championship in Kona.  With its aerodynamics trickled down from the development of the E-119 and its fork design adopted by the pro peloton ridden Nitrogen, the E-117 Tri PLUS, Argon 18's mid range  triathlon/time trial frameset, is a true bike designed to meet the needs of all triathletes and time trialists.

Whilst geometrically equal to its E-117 sister, the E-117 Tri PLUS offers a higher quality tubing and carbon layup providing for a weight and stiffness advantage. The Tri PLUS also comes fully equipped with aero top tube and rear seat post mounted drinking and storage solutions.

Frameset includes - Frame, fork, Press-fit headset, seat post, seat clamp, front and rear brakes, TRP brake levers, top tube mounted food storage, rear seat post mounted storage system for nutrition/tools.
