Cirex
Fast, faster, Cirex! The race fully is the most efficient answer to the ever-increasing demands of the racing world. In addition to its light weight, the frame offers a balanced geometry for demanding descents and steep climbs. The efficient 100-mm suspension smoothes out all bumps in the trail without having you waste energy on pedalling. If you are looking for even more downhill vigour, you should pick the "downcountry" option with 120 mm of travel.









Details
When should you get the Cirex? If you appreciate a lightweight bike with swift propulsion. Thanks to the front suspension fork and the rear shocks, you’ll have optimum grip. Whether you opt for the 100-mm suspension or the 120-mm option – the MTB-fully by Simplon offers maximum fun in rough terrain.
Features
With the update to its predecessor, Cirex 120, Simplon knocked one out of the park! The more efficient geometry – with a flatter steering angle, steeper seat angle, longer reach, etc. – makes demanding terrain a piece of cake.
The new generation of the Cirex also impresses with its light weight and extremely high rigidity. Uncompromising propulsion guaranteed!
Chainstay protectors on the inside of the chainstays provide comprehensive frame protection. Damage to the paintwork caused by dirt and rock impact, as they’re kicked up by the tyre, is now a thing of the past!

Technology
Listen up, race fans! The bike’s Flexlink replaces an entire joint, which increases stiffness. At the same time, this reduces wear and maintenance costs.
On the new Cirex, chafing cables are a thing of the past: On the race fully, all cables, such as the shift and brake cables, are routed internally through the frame. The pivoting cable guide on the main wheel bearing not only cleans up the look of the bike, but also raises the bar in terms of advanced cable routing.
