Building upon the award-winning XQUARONE EX with NAILD’s R3ACT 2Play suspension platform, Polygon have now released their new gravity bike – the XQUARONE DH. This bike has been designed to not only be a 218mm pure racing machine but it also has the versatility to ride like an All Mountain bike given its unique integration with the R3ACT 2Play suspension platform.
The XQUARONE DH’s frame is carbon from tip to tail (excluding the rocker links and the stanchion that the swingarm slides on), part of the reason Polygon were able to keep the weight down to a very reasonable 3.9kg, including the shock. Super Boost 157 spacing has begun to pop up on a handful of trail and enduro bikes, and it also makes an appearance here on the XquarOne DH. That means there’s a 12x157mm rear end matched to BB92 bottom bracket, rather than the BB107 or threaded 83mm bottom bracket shell that you’d typically expect to find on a DH bike.
The NAILD suspension design utilises a swingarm attached to the front triangle by a short aluminium link. The shock is then driven by a yoke that wraps around the seat tube. There’s one more element to this system Ã¢â‚¬â€œ an aluminium stanchion tube that the swingarm slides over. No, it’s not another shock, instead, this layout allows for the bike to have a consistent amount of anti-squat (between 98 Ã¢â‚¬â€œ 110%) throughout the entire gear range. This means the bike will pedal exceptionally well even if you’re at the bottom of the cassette and need to throw in a couple extra pedal strokes to get speed for a jump, or putting down the power for a final sprint to the finish line.
