SIMPLON Cirex tested by Bikeboard

A sporty race bike with "down-country" option

One thing is certain for the testers of Bikeboard: The Cirex XX1 Eagle AXS by SIMPLON is a classic race bike, but it can definitely do more than that! With an optional 120 mm travel and “down-country” option, the lightweight MTB makes hitting the trails an incredibly fun experience.

Special features of the MTB

According to Bikeboard, the 2021 version of the Cirex scores with its two-pronged approach: The reduced travel of 100 mm on the MTB is perfect for uncompromising racers. Those who want to hit the trails can select a longer shock in the configurator (Fox Float DPS), which increases the rear suspension travel to 116 mm. 

Other striking features: the no-frills design and reimagined frame. SCS+ technology is used on the Cirex. This means that the main frame tubes have an almond-shaped cross-section, which keeps the frame vertically elastic and comfortable. The lateral edge of the tube increases impact resistance. 

Sophisticated features: On the full-suspension bike, all cables such as the shift and brake cables run inside the frame. The pivoting cable guide on the main bearing gives the bike a clean look and prevents cable rub. 

Geometry & fit 

The update to the predecessor model Cirex 120 boasts a more efficient geometry: flatter steering angle, steeper seat angle, longer reach. This makes even challenging terrain easy to master.

Bikeboard's verdict on the fit: "The pressure between the buttocks and hands is very well-balanced, and you stay pain-free and comfortable even after hours on the saddle.”

SIMPLON Cirex put through the endurance test

The Cirex is all about sportiness, even in the 120 mm version: "While sitting down or while riding out of the saddle – the Cirex only knows one direction and that is forward." Almost any climb – long, short, steep or slippery – can be mastered with this race MTB. The testers were also impressed by the agility of the front: It makes challenging situations easy to manage. 

Downhill, the mountain bike really shows off its strengths: "It’s perfectly balanced, and you always have a good feel for both wheels". Even when it gets slippery, the Cirex can quickly be controlled again.
