Argon 18 E-117 105 Di2 Bike Info
The Argon 18 E-117 105 Di2 Bike is a carbon triathlon frame built around a clear premise: a first dedicated tri bike shouldn't require a round of upgrades before it's race-ready. At $6,699, it arrives as a complete package — the E117 carbon frameset, Shimano 105 Di2 electronic shifting, ATTEN L42 wheels, and 51 Speedshop tri extensions fitted from the factory. The spec doesn't ask you to substitute anything before your first race. The bike handles that for you.
The E117 carbon frame is Argon 18's dedicated triathlon platform, engineered specifically for multisport demands rather than adapted from a road design. Its 78-degree seat tube angle — consistent across all five sizes — positions the rider forward over the bottom bracket, shifting load away from the quads and hamstrings during the bike leg. That preservation matters most at the bike-to-run transition, where poor saddle positioning accumulates as muscle fatigue over distance. Argon 18 extends this thinking into the frame geometry itself through the Argon Fit System: bottom bracket drop, chainstay length, and wheelbase are adapted per frame size, and the fork is custom to each size to prevent toe overlap. A rider on a size XS — designed for a 47-50cm rider — gets geometry proportional to their body, not a compressed version of a larger frame. The 3D System handles front-end fit at the head tube, allowing stack height adjustment without a fork swap and without compromising steerer stiffness — practical for a triathlete still dialing in position between events. Cables are fully integrated throughout the frameset.
Shimano 105 Di2 handles the drivetrain. The R7150 derailleurs run on the same electronic architecture as Dura-Ace and Ultegra — identical shift logic, multi-shift capability, and junction box electronics, with a performance gap that narrows considerably once you're on the road. The 52/36 chainring setup and 11-34 cassette give useful range across sprint-distance flat courses and longer events with elevation. Sprint shifters at the bar ends keep gear access within reach without requiring you to leave the aero position. The cockpit is Argon 18's own integrated system — stem and bar as a single unit — paired with 51 Speedshop Custom Extensions. Those extensions use an airfoil cross-section and sit at a 30-degree grip angle, a neutral wrist orientation that reduces hand fatigue on sustained efforts. Braking runs through Argon 18's Integrated Brake System, with the calipers built directly into the frame structure rather than bolted externally — lower drag, cleaner lines.
The ATTEN L42 wheelset is Argon 18's own wheel brand, built around a 42mm rim profile. That depth balances aerodynamic gain against crosswind handling — more efficient than a shallow rim while staying predictable in mixed conditions. Vittoria Corsa N.EXT tubeless-ready tires in 700x28 run from the factory on the ATTEN rims, and the E117 frame clears up to 30mm, leaving the option to run slightly wider rubber on rougher courses. The ISM PR1.0 saddle is a deliberate tri-specific choice: the relieved-nose design allows forward pelvic rotation into the aero position without the pressure buildup that accumulates over distance on a standard road saddle — a detail that makes longer bike legs noticeably more manageable.
The E-117 105 Di2 fits two riders well: someone transitioning from a road bike into a purpose-built tri platform for the first time, and a more experienced short-course racer who wants electronic shifting without paying into the Ultegra or Dura-Ace tier. The size range runs XS through XL — broader than most in this category — and the Argon Fit System's per-size geometry means the bike performs as intended across the full range rather than concentrating fit quality around medium sizes. Available in Black Stealth and Flaming Red. For athletes ready to race on geometry built specifically for triathlon rather than adapted from it, the E117 is where to start.
