Pricing is very good!
Great suspension package.
No-nonsense design.


Seems to be a bit of internal cable rattle going on.
Both wheel sizes not available in all frame sizes.

Polygon have been plugging away solidly over the past few years, building up a tidy contingent of no-nonsense, sharply priced, alloy trail bikes. We’ve reviewed plenty of them over recent times, and we’ve enjoyed watching them get better and better with each iteration, ticking all the boxes that riders demand, but not sending anyone into financial ruin

Watch our first impressions vid below:

This Siskiu series of bikes doesn’t have the glitz of Polygon’s mind-blowing Xqaurone EX uber bike. They’re pitched at the rider looking for excellent value, not cutting-edge innovation, and so you’ll find effective but uncomplicated suspension designs, with practical, user-friendly components. The Siskiu N9, here, is the hardest hitting bike in the Siskiu line, with 160 or 170mm travel, and angles that have strutted right off the Enduro catwalk.

The short head tube suits us, but taller riders will be running a few spacers beneath the stem we’d say. Note the internal cabling.

Wheel sizes? The N9 is available in both 27.5 and 29er, but not in all frame sizes. Large and x-large frames get 29er wheels, small frames get 27.5″ wheels, and if you’re lucky enough to ride a medium, you can choose either wheel size. Want little wheels on a big frame? Sorry, no dice, Captain. We’re riding a medium with 29er wheels – give us the big wagon wheels any day, it’s confidence we crave.

The 500% gear range will come in handy on big days out.

Polygon come to you direct, keeping the costs down, and it’s hard not to be impressed by the excellent component spec for the money. Coming in at $3699, the bike is dressed in Enduro finery from FOX (with a 36 and DPX2 shock), SRAM GX Eagle and Scwhalbe’s Magic Mary tyres. The TRP four-pot brakes scared the hell out of us on our first test ride, as they took a lot longer to bed-in than a Shimano or SRAM brake, but they’re working well now. The majority of the kit is all Entity, which is Polygon’s in-house component label.

It’s awesome that Polyon have invested wisely in high quality suspension.

It’s no featherweight, at 14.75kg, but who’s really fussing, anyhow? You buy a bike like this and clearly you’re not racing the climbs. But we’ll sure as hell be racing the descents, to see how this bike compares to steeds twice the price. Stay tuned!

With many exotic Enduro frames costing $1000 more than this whole bike, it’s easy to see the appeal of this clean, sensible machine.
