Argon 18 E-119 Tri+ Disc FAQs
Everything you need to know before ordering a Argon 18 E-119 Tri+ Disc through Tri Harder.
What makes the E119 different from other triathlon bikes?
The E119 integrates the brake calipers directly into the frame and is designed around full-system aerodynamics — the bike, rider position, and on-bike storage are all optimised together rather than treated separately.
What's the weight/performance advantage over the previous E119?
Argon 18 states up to a 10W advantage over the previous generation, from frame optimisation, system integration, and compatibility with advanced aero wheelsets.
What groupset options are available?
Six: a £6,000 frameset-only option, Shimano Ultegra Di2, SRAM Force AXS E1, SRAM Force AXS Classified Powershift, Shimano Dura-Ace Di2, and SRAM Red AXS — up to £13,550.
Does the E119 come with disc brakes?
Yes — fully integrated disc brakes, concealed within the frame for both aerodynamic and aesthetic reasons.
What We Think Of The Argon 18 E-119 Tri+ Disc
The E119 is our flagship tri bike, and it's built for one thing — going as fast as possible for as long as possible. Full brake integration, a hidden toolkit, and genuine full-system aero thinking rather than just a fast-looking frame. If you're chasing Ironman-distance speed and already know your position, this is the bike.
What we like
- Full-system aero approach — the bike is designed around nutrition/hydration storage too, not just tube shapes
- Concealed disc brake integration is a genuine first-of-its-kind detail, not marketing fluff
- Six build options from a £6,000 frameset up to £13,550 — real flexibility at the top end
- Proven race pedigree — this is the bike behind several long-course record rides
Worth knowing
- This is a race bike, not a training bike — the aggressive position rewards riders who've already dialled in their fit
Best For
Experienced triathletes and long-course racers who know their position and want the fastest, most integrated bike Argon 18 makes.
