Argon 18 has been designing triathlon and time trial frames since 1989, and the E-117 carries that experience into a complete race build: carbon frame and fork, full Shimano Ultegra Di2 electronic shifting, an integrated brake system, Scope R5 57mm carbon wheels, and the brand's proprietary 3D fit system. At $7,999, it arrives as a race-ready machine built around solving triathlon's most persistent challenge — fitting the rider correctly without compromising the bike's aerodynamics.\u003c\/p\u003e\n\u003cp\u003eThe 3D System is the headline feature of the E-117, and it's a substantive engineering difference rather than a marketing label. Traditional triathlon cockpits offer roughly 30mm of available stack adjustment, which forces many athletes into positions that don't fully match their fit or toward aftermarket solutions that add drag. Argon 18's 3D System replaces the conventional top bearing arrangement with a custom spacer in which the bearing is integrated, available in three different heights for each frame size. The result is 60mm of available stack adjustment — double the conventional range — without stacking standard spacers. The integrated bearing design also preserves 5–11% more frontal rigidity than standard spacers at equivalent heights, so the additional adjustability doesn't trade away cockpit stiffness. For athletes who revisit their fit seasonally or build toward different race distances over time, this system is genuinely useful across the life of the bike.\u003c\/p\u003e\n\u003cp\u003eThe geometry is engineered specifically for long-course triathlon. A 78° seat tube angle across all five sizes positions the rider aggressively over the pedals — loading the posterior chain for sustained power output while reducing anterior muscle strain during the bike-to-run transition. The 413mm chainstay is consistent across the full size range. Stack and reach adjustability is wide: the medium size accommodates armpad stack from 576 to 700mm and armpad reach from 425 to 523mm, covering a broad range of athlete proportions without custom fabrication. The Argon 18 Integrated Cockpit pairs with 51 Speedshop Custom Extensions — airfoil-profiled to reduce drag at the arm interface — on a 40cm bar width suited to most triathlon athletes.\u003c\/p\u003e\n\u003cp\u003eThe integrated brake system is an aerodynamic decision with a functional payoff. Housing the brake calipers within the frame structure eliminates drag at the fork crown and rear triangle, where externally-mounted calipers create significant turbulence. TRP TR140-25 rotors at 140mm provide the braking performance. The drivetrain is Shimano Ultegra Di2 throughout — R8150 front and rear derailleurs, R8100 crankset with 52\/36 chainrings, Shimano SM-BB72 bottom bracket, and 12-speed 11-30T cassette. Shimano SW-R9150 sprint shifters mounted at the bar ends keep shifting accessible from the aero position without moving the hands.\u003c\/p\u003e\n\u003cp\u003eScope R5 57mm carbon disc wheels run front and rear — tubeless-ready and deep enough for aerodynamic advantage on the flat and rolling courses that define long-course triathlon. Vittoria Corsa N.EXT TLR 700x28 tires pair rolling resistance performance with tubeless puncture resistance for race-day reliability. The ISM PR1.0 saddle is engineered for the forward pelvic rotation that a 78° seat angle creates — it eliminates soft-tissue pressure in the aero position without requiring saddle tilt adjustments that undermine position accuracy. The frameset is available in Flaming Red and Black Stealth.\u003c\/p\u003e\n\n\n\u003ch3\u003eDesign Benefits\u003c\/h3\u003e\n\u003col class=\"design_benefits\"\u003e\n\u003cli\u003e\n\u003cstrong\u003e3D System headset:\u003c\/strong\u003e Integrated-bearing spacers in three heights per size provide 60mm of stack adjustability — double the conventional range — while preserving 5–11% more frontal rigidity than standard spacers at equivalent heights.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame-integrated brake system:\u003c\/strong\u003e Calipers housed within the frame eliminate aerodynamic drag at the fork crown and rear triangle without sacrificing braking performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e78° seat tube angle across all sizes:\u003c\/strong\u003e Positions the rider for tri-specific power output and minimizes hip flexor strain during sustained efforts, supporting faster transitions to the run.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e51 Speedshop airfoil extensions:\u003c\/strong\u003e Arm-hugging profile reduces turbulence at the rider-cockpit interface, where body position creates significant drag in the aero position.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISM PR1.0 saddle:\u003c\/strong\u003e Engineered for the forward pelvic rotation of steep-angle tri geometry — eliminates the soft-tissue pressure that causes athletes to compromise their aero position over long race efforts.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch3\u003eFinal Take\u003c\/h3\u003e\n\u003cp\u003eThe Argon 18 E-117 Ultegra Di2 is for athletes who want a triathlon bike that was designed for triathlon — not a road platform adapted with clip-on bars.

At $7,999, it delivers a complete and race-capable build that works for anything from a first Ironman to a competitive age-group program, without requiring significant component investment after purchase.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Argon 18","offers":[{"title":"Flaming Red \/ XS","offer_id":43978248781868,"sku":"117D.XS.374B.2D.1","price":7999.0,"currency_code":"USD","in_stock":true},{"title":"Flaming Red \/ S","offer_id":43978248716332,"sku":"117D.S.374B.2D.1","price":7999.0,"currency_code":"USD","in_stock":true},{"title":"Flaming Red \/ M","offer_id":43978248683564,"sku":"117D.M.374B.2D.1","price":7999.0,"currency_code":"USD","in_stock":true},{"title":"Flaming Red \/ L","offer_id":43978248650796,"sku":"117D.L.374B.2D.1","price":7999.0,"currency_code":"USD","in_stock":true},{"title":"Flaming Red \/ XL","offer_id":43978248749100,"sku":"117D.XL.374B.2D.1","price":7999.0,"currency_code":"USD","in_stock":true},{"title":"Black Stealth \/ L","offer_id":44045872037932,"sku":"117D.L.374A.2D.1","price":7999.0,"currency_code":"USD","in_stock":true},{"title":"Black Stealth \/ M","offer_id":44045872889900,"sku":"117D.M.374A.2D.1","price":7999.0,"currency_code":"USD","in_stock":true},{"title":"Black Stealth \/ S","offer_id":44045873741868,"sku":"117D.S.374A.2D.1","price":7999.0,"currency_code":"USD","in_stock":true},{"title":"Black Stealth \/ XL","offer_id":44045874200620,"sku":"117D.XL.374A.2D.1","price":7999.0,"currency_code":"USD","in_stock":true},{"title":"Black Stealth \/ XS","offer_id":44045874298924,"sku":"117D.XS.374A.2D.1","price":7999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/argon-18-e-117-ultegra-di2-bike-1986970.jpg?v=1771293971","url":"https:\/\/ricycles.com\/es\/products\/argon-18-e-117-ultegra-di2-bike","provider":"RA Cycles","version":"1.0","type":"link"}
