About this bike
The E117 is Argon 18's entry point into dedicated triathlon racing — and it doesn't feel like an entry-level bike. Built around Argon 18's integrated brake system and finished with a full Shimano 105 groupset, it's a versatile, race-ready platform for a first serious tri or TT build. Superb handling and an adjustable setup make it as comfortable on long training rides as it is on race day.

Built, Checked, Tested

Is the Argon 18 E117 a good first triathlon bike?
Yes — Argon 18 positions the E117 specifically as the entry point into their triathlon range, and it’s built for stable, forgiving handling rather than the twitchier feel of a full race bike, which makes it a genuinely good choice for a first dedicated TT setup.
Will Shimano 105 hold up for regular triathlon training and racing?
Shimano 105 R7100 is a mechanical, reliable groupset — it’s a common choice for age-group triathletes because it’s straightforward to service and performs consistently through long training blocks, not just on race day.
What size is this bike?
This particular bike is a Small, suited to riders roughly 51–53cm frame size. Come in for a bike fit to confirm — reach and stack adjust independently via the Profile Design aerobars regardless of frame size.
Does the E117 come with disc brakes?
Yes — it uses Argon 18’s own Integrated Brake System with TRP rotors (140mm front and rear) for consistent stopping power in wet or dry conditions.
Can I fit wider tyres than the stock Vittoria Rubino Pro IV?
The frame has clearance up to 30C (32mm), so there’s room to size up from the stock 28mm tyres if you want more comfort or grip without changing the frame.
Is a bike fit included?
Yes — every bike from Tri Harder comes with a free bike fit, so you’ll leave with your position properly dialled in, not just a bike off the shelf.
