Description:
Argon 18 E117 Shimano 105 Di2 Integrated Cockpit — Race-Ready Aero Performance for Triathlon and TT
The Argon 18 E117 is a dedicated triathlon and time-trial bike built for athletes who want a real aero race position, integrated disc braking, and value-driven performance from Argon 18's triathlon platform. It is designed for serious triathletes, TT competitors, and riders moving from a road bike setup into a purpose-built bike with forward triathlon geometry and adjustable fit.
Choose the E117 Shimano 105 Di2 when you want electronic shifting and the integrated-cockpit E117 experience at a lower MSRP than Ultegra Di2. The 105 Di2 drivetrain gives precise, repeatable electronic shifts, while ATTEN L42 wheels and 51 Speedshop extensions keep the build fast, comfortable, and accessible.
Who should buy this model?
This build is best for riders who want the most cost-effective electronic-shifting E117, long-course triathletes who value consistent shifting in aero position, and customers who want an integrated cockpit without moving up to Ultegra Di2.
Why this E117 over the other builds?
Compared with Shimano 105 mechanical, this model upgrades to Di2 electronic shifting and the Argon 18 Integrated Cockpit. Compared with Ultegra Di2, it trades some drivetrain prestige and wheel performance for a more approachable price.
