SQUARE ONE EX9

The Square One EX Series is a departure from the old way of classifying bikes and creates a new paradigm where travel no long determines discipline. The NAILD suspension design works in conjunction with Polygon's frame construction to give a ride unlike anything else. The bike is designed to have a short rear end for tackling technical terrain and to provide quick cornering. Equipped with the elevated chainstay that is unique to the NAILD R3ACT- 2Play Suspension System, Square One EX acts as an extension of rider’s movement. Square One EX helps riders get more speed and extends their riding range. Square One bikes are able to move over obstacles quicker which improves lap times, reduces rider fatigue and increases on trail confidence. All Square One EX frames are built around 27.5 wheels and feature a full ACX carbon frame with 180mm suspension travel.


“The Square One is the best bike I've ever ridden. As I'm spending more and more time on the Square One I'm realizing how incredibly capable it
is. I find myself dreaming of the possibilities that the Square One will open up. The Square One is going to allow me to cover much longer
distances and climb bigger mountains than ever before without sacrificing the enjoyment of riding a bike that can handle any type of terrain on
the way back down” - Mick Hannah


“Before riding the Square One I didn't really know what to expect. As soon as I got my hands on it, I went for a pedal around the block, I didn't
return for 2 hours! I've always wanted a bike that I can take on adventures and bigger missions that can still handle everything I throw at it plus
be confident to push my own limits. I'm excited to challenge more rides and terrains on the Square One” - Kurt Sorge
