IAx Advanced 105

This road-speed measure focuses on efficient pace on asphalt, where drag and rolling resistance matter most. Compared with more speed-first builds, this build is shaped by narrow road tires that keep resistance low, an aero-leaning setup that reduces drag at higher speeds, a solid drivetrain that supports efficient riding, and a relaxed posture that gives up some aero efficiency.

Climb score: 3.3/10. Within Road bikes, it sits below average. For hill work, the easiest gear is moderate. In numbers, the low gear is roughly 27.0 gear inches. In its peer group, it lands around the easier ~58% for low-gear climbing. Think of “gear inches” like a difficulty score for your easiest gear: lower = more spin-friendly on climbs. It can climb, but you’ll likely prefer smoother pacing on longer hills. Specs can vary by size and build, and some manufacturer details aren’t always published, so treat this as a strong guide rather than a guarantee.

As a triathlon bike, with a 10.0/10 aero score, it’s at the sharp end of aero priorities with a clear speed-over-everything bias. Put simply, it’s strongly speed-focused, designed to reduce wind drag when you’re riding fast. The wheels are on the shallower side (around 30mm), so frame shapes and position likely matter more than wheel depth here. This looks like a practical wheel choice rather than a max-aero choice. Tyres around 25mm fit a faster road setup and usually keep drag in check. Details like hidden cables and a cleaner cockpit can add up to small aero gains at speed. On fast flats and windy days, it’s built to feel like it wastes less energy pushing air.

Race / Pro fit - an aggressive tuck meant for hard efforts over pure comfort. That's driven by handlebar height is roughly 150 mm lower than the saddle (very large drop), and how far you'll be stretched forward is about 593 mm (very long). Plan for roughly 46 degrees of lean. Front-end spacers are estimated around 6 mm.

Why this fit flexibility rating: Separate bar and stem components keep fit changes practical, Cable routing is on the simpler side, which helps adjustability. Another point: Seatpost info looks fairly neutral, so most fit change comes from cockpit choices. Overall, it is Moderately Adjustable.

This scores 1.8/10 for comfort, so it feels very firm out on the road. That’s why it’s labeled Race-Stiff. It’s running about 25 mm tires on 700c wheels, and you feel more of the road texture with narrow tires on chipseal and broken pavement. The posture is race-leaning (posture 8/10, torso ~46°), which puts more weight forward, so you notice more feedback through the hands and saddle.

The price feels a touch strong for the parts listed. The value score is 1–10. Higher means better value for money; lower means the price is high for what you get. Uses MSRP as a baseline; real-world prices can be lower (discounts can change the value). On the spec comparison, it sits roughly 30% above what similar builds typically cost. Compared with similar bikes, it trends a little expensive (cheaper than about 35% of listings). To anchor it: price €4.199 versus an estimated €3.234 for a similar build. Some manufacturer details aren’t fully published, so use this as a helpful direction rather than a final verdict. Bottom line: you may be paying extra versus similar options.

This setup is focused on speed and efficiency on paved roads. The tire size is around 25 mm, which is typical for fast road setups. Overall, the setup matches this surface range well.
