First journey: Polygon’s $3,299 Colossus N9

Polygon’s new Colossus N9 made its first look at Sea Otter this 12 months in all its city camo painted glory, full with an IFS suspension format first seen on the Mount Bromo eMTB. The bike has 29” wheels entrance and rear (it isn’t compound-wheel suitable), and 170mm of journey. After a season of enduro racing and refining, it is now out there, with an aluminum body and a $3,299 price ticket that contrasts with the costlier carbon machines launched lately.

For the worth, Polygon has put collectively a wonderful elements package deal. Suspension is dealt with by Fox 38 Efficiency forks with grip dampers and 230 x 65mm Float X2 shocks. SRAM Code R brakes with 200mm rotors assist preserve pace beneath management, and Shimano takes care of shifting with an XT derailleur, SLX cassette, and XT cranks. Sadly, these cranks are 175mm lengthy, which will not be perfect for riders on rockier terrain. 2.6” large Schwalbe Magic Mary tires are mounted on Entity rims with a 35mm inner width.

Collosus N9 particulars

All of that provides as much as a paltry 39.25 kilos (17.8 kg) – Colossus looks as if a really applicable title given these numbers.
Body particulars

The body of the Colossus is clearly stiff; Every part from the ahead shock mount to the double-braced swingarm seems prefer it’s constructed to take a beating. All these hyperlinks and shock positioning take up some valuable water bottle actual property, which means solely a ‘common’ sized bottle will match within the entrance triangle. Nonetheless, it is higher than nothing. There’s additionally no in-frame storage or accent mounts for viewing. One other lacking function is a common derailleur hanger, more likely to be fairly a ‘will need to have’ if the rumors about SRAM’s subsequent technology drivetrain are true.

There is a ribbed chainstay protector, though it is a little bit brief – extra protection on the entrance of the chainstay will assist forestall the paint from chipping with the chain. The brake, derailleur, and dropper strains are routed internally, although there’s actually nothing contained in the body to maintain them from shaking round—fortunately, I did not discover a lot noise on my take a look at bike.

It is good to see the Colossus specced with a sequence information and bass guard, as crunching the chainring is an effective technique to preserve the damper on a race run. There’s additionally body safety on the underside of the downtube to maintain it secure from flying rocks or truck tailgates.


A lot of the colossus’ geometry numbers are in keeping with what has change into customary for this class. The pinnacle angle sits at a low, 63.5-degree with a 170mm fork, the attain is 480mm for the bigger dimension, and the seat tube angle is 77-degree. Chainstays are on the brief aspect throughout the board at 435mm – they do not change with every dimension, a apply that an increasing number of corporations are adopting.

Suspension design

Polygon appears to have a penchant for suspension designs which can be a bit totally different from the norm – there was the wild-looking floating dual-link FS3 design in 2014, and the much more aesthetic SquareOne EX9 with its R3ACT suspension. In 2017. The Colossus retains the development alive, although the general look is not more likely to be as polarizing as these different two examples.

It makes use of a model of the IFS (Impartial Floating Suspension) design first seen on Polygon’s Mount Bromo eMTB. The idea is that the 2 decrease counter-rotating brief hyperlinks can be utilized to direct the axle path, whereas the seatstay and rocker hyperlink are used to regulate the leverage curve, or how a lot progress there may be. All these hyperlinks could make it simpler for designers to get the suspension traits they need, however meaning there are 16 cartridge bearings to maintain observe of, and the bottom set of bearings instantly in entrance of the rear wheel, proper the place the mud and. Rubbish will find yourself in a sluggish journey.

Anti-squat percentages are fairly excessive, sitting at round 121% earlier than the bike lets up slowly because it goes by its journey. The scaling of the chart makes the development look fairly excessive, nevertheless it’s truly about 19%, which is fairly regular for a long-travel enduro bike.

Automobile impressions

For anybody who thinks weight does not matter, I encourage you to take the Colossus out for a spin. I’ve spent a whole lot of time — years, actually — pedaling round on a motorbike within the 40-pound vary, and I am removed from chubby, however I am going to admit it is a little bit arduous to muster the motivation to get there. Lengthy pedal out on this heavy bike. Who is aware of, possibly I am going comfortable.

Sure, I do know the Colossus is not some loopy costly, carbon fiber marvel bike, and given its price ticket and stable elements package I am keen to chop it a little bit slack within the weight division, however 39 kilos continues to be fairly cool. I can not assist however marvel how a lot weight and problems would have been saved by going with the tried-and-true Horst Hyperlink format as a substitute of sticking to the hyperlinks required for an IFS suspension format?

Aside from the burden, Colossus does Pedal nicely, particularly for a motorbike with 170mm of journey. The suspension is so quiet that I did not really feel the necessity to flip the Float X2’s climb change, and even on lengthy hearth highway grands I used to be completely content material with it within the open place. The chainstays are on the brief finish of the spectrum, however the steep seat angle and slack head angle work collectively to assist preserve the bike from feeling prefer it desires to loop out on steep climbs. Though it is a pretty substantial, sluggish bike, I did not discover it too tough to maneuver by tight switchbacks or extra technical sections – it is actually the slow-rolling tires and total heft that give it a extra subdued really feel when going uphill.

When it comes right down to it, the Colossus is not the quickest out of the gate, nevertheless it feels very robust and prepared for something when it will get up to the mark. The rear finish could be very stiff, and that function mixed with brief chainstays makes it straightforward to snap the rear wheel out and in of tight turns, although that comes with barely much less traction and stability – at occasions it feels just like the again of a colossus. The wheel was extra more likely to transfer by curves reasonably than drawing a clear arc. It does not have essentially the most flattering, too-fluttery suspension both; Whereas it is going to take the sting off the tough stuff, it will not wipe out these huge hits like different bikes on this journey bracket.

Total, the Colossus N9 presents nice worth in the case of elements area, and the geometry will not maintain it again until you step it down, extra technical trails. Weight is the most important draw back, although this will not be a priority for riders who spend most of their time driving contained in the shuttle automobile or sitting on the chair carry.
