The Race

The race has an altitude drop of 2400m over around 25km, though that distance is approximate due to the open slather of line choices allowed by the sparse course marking posts. Fabien takes some ‘interesting’ options and despite the fatigue and unimaginable arm pump, manuals across the finish line in 4th place.

That’s a funky rear end. How will it ride?

The Bike

To even make it to the finish alive would require a half decent ‘enduro’ rig, but combining tobogganing with a podium finish is another level. We previewed the polarising Polygon Square One EX series a few months ago, and have just got our hands on one for a full review. Stay tuned over the coming weeks. Now to find a glacier…

Polygon Bikes Reveal The New Square One EX Series

Holy seatstay!
The new Square One EX looks more like NASA research than a bicycle- we’re excited.

Wow. Polygon have come out with something completely new here, a real step away from what everyone else is doing in terms of travel, frame and suspension design.

Everyone loves geometry, so you can check out the Square One’s angles below.

We definitely weren’t expecting Polygon to come out with a 180mm, 27.5″ bike with this sort of design, but we’re seriously excited to get our hands on one. Whilst the aesthetics won’t float everyone’s boats, its how the bike rides that counts, and from a glance at the spec and geometry it looks like an absolute beast of a bike.

Read on to see what Polygon have to say about the Square One EX range.

Polygon Bikes believes that each of our customers want one bike that is easy to be maintained and can be ridden anywhere.

Short chainstays should make the Square One easy to get onto one wheel.

The quest to deliver new and special products to our consumers led to the collaboration between Polygon and NAILD. Both brands shared a goal to bring the best riding experiences possible to our customers. Not only did Polygon and NAILD want to create a “one bike” quiver-killer, we wanted to redefine how people classify mountain bikes with a truly capable machine.

The Square One EX Series is a departure from the old way of classifying bikes and creates a new paradigm where travel no longer determines discipline.

“The NAILD suspension design works in conjunction with Polygon’s frame construction to give a ride unlike anything else. We designed the bike to have a short rear end for tackling technical terrain and to provide quick cornering thanks to the elevated chainstay that is unique to the NAILD R3ACT- 2Play Suspension System”, said Zendy Renan, Product Development Manager for Polygon Bikes.

Square One EX acts as an extension of rider’s movement – body mechanics are one of the critical aspects we focused on during the development process of NAILD’s concept about vertical wheel path and the use of shaft systems.

All Square One EX frames are built around 27.5 wheels and feature a full ACX carbon frame with 180mm suspension travel.
