Bike Check: Mick Hannah's Mixed Wheel Size Polygon XquarOne DH


on the clock this season. Mick says that it's the only set up he's experimented with, but likes the way it rides so he's sticking with it as is for now.This is the second year that the team has been running this frame. Mick was on a size large last year but has switched over to the XL for at least the time being.

Mike Kazimer did an in-depth first ride on the XquarOne last season and explained the system well. Here's his quick, "how it works" if you don't feel like surfing back to the article: "The swingarm is attached to the front triangle by a short aluminum link, and the shock is driven by a yoke that wraps around the seat tube. That description would work for a number of dual-link designs, but there's one more element to this system – an aluminum stanchion tube that the swingarm slides over. No, it's not another shock, just like the two short rods on Yeti's Switch Infinity design aren't tiny shocks either. Instead, this layout allows for the bike to have a consistent amount of anti-squat (between 98 – 110%) throughout the entire gear range. In theory, that means the bike should still pedal well even if you're at the bottom of the cassette and need to throw in a couple of extra pedal strokes to get speed for a jump, or putting down the power for a final sprint to the finish line. The NAILD design works best with a shock that has a very low amount of compression and rebound damping"
Trickstuff's Maxima brakes on board to deliver copious amounts of stopping power. Galfa pads and rotors, 203mm. Mick's handlebars are at 780mm. He'll occasionally run a narrower bar, especially for urban races.

Tire pressures are 26 in the front and 27 in the back. Tubeless with Kenda Hellcats and no inserts of any sort...simply air. There's a 29" wheel up front and a 27.5" out back. Snug clearance on the SR Suntour fork. E*thirteen wheelsets keep things spinning.

Custom shock set-up from Fast Suspension with a 550lb spring.

75 psi in the fork. Riders are constantly trying out different set-ups and Mick says the track in Rotorua makes the front of the bike want to dive a lot with a lot of the holes in the faster steeper sections. He runs more damping and more volume spacers there to keep the bike from diving.

The eye-catching suspension design on the XquarOne delivers 220mm of travel. The R3ACT system provides a lot of pedaling efficiency and anti-squat even when you're deep into the gear range.

An integrated fender helps to keep the muck off of the suspension.
