First trip: Polygon’s $3,299 Collosus N9

Polygon’s new Collosus N9 made its first look in all its city camo glory at Sea Otter this 12 months, full with the IFS suspension structure first seen at Mt. Bromo eMTB. The bike has 29 inch entrance and rear wheels (not suitable with mixture wheels) and 170mm of journey. After a season of enduro racing and refinement, it is now obtainable, with an aluminum body and $3,299 price ticket that stands out in stark distinction to the ultra-expensive carbon machines which were launched recently.

For the worth, Polygon has put collectively a wonderful bundle of components. The suspension is managed by Fox 38 Efficiency fork with Grip shock absorber and 230 x 65 mm Float X2 shock absorber. SRAM Code R brakes with 200mm rotors assist hold velocity in examine, and Shimano takes care of shifting through a KST derailleur, SLX cassette and KST Kurban. Sadly, these levers are 175mm lengthy, which might not be ideally suited for riders on rockier terrain. Schwalbe Magic Mari 2.6-inch tires are mounted on Entity rims which have an inner width of 35 mm.

Body particulars

The colossus’ body is visibly massive; every thing from the entrance shock to the dual-bracket flywheel makes it appear like it is constructed to take a beating. All these hyperlinks and the place of the shock take up some valuable water bottle area, that means that solely a ‘common’ sized bottle will match within the entrance triangle. Nonetheless, it is higher than nothing. There may be additionally no in-frame storage or any equipment to be seen. One other lacking characteristic is a common derailleur hanger, one thing that can seemingly turn into extra of a “will need to have” if the rumors about SRAM’s next-generation drivetrain are true.

There’s a ribbed chainguard, though it’s kind of brief – extra protection in direction of the entrance of the chainring would assist hold the paint from chipping off the chain. The brake, derailleur and dropper strains are routed internally, though there’s nothing within the body to cease them rattling round – fortunately I did not discover an excessive amount of noise on my take a look at bike.

It is good to see the Collosus outfitted with a sequence information and kick guard, because the crunch of a chainring is an effective method to dampen a racing run. There may be additionally a body guard on the underside of the down tube to maintain it secure from flying rocks or the boot of a truck.

Geometry

Many of the geometric numbers of the Colossus are in step with what has turn into the norm for the class. The pinnacle angle is a relaxed 63.5 levels with a 170mm fork, attain is 480mm for the big, and the seat tube angle is 77 levels. Chainrings are on the shorter facet at 435mm throughout the board – they do not change with every dimension, a apply an increasing number of firms are adopting.

Suspension design

Polygon appears to have an affinity for suspension designs which can be slightly totally different from the norm – there was the wild floating dual-link FS3 design again in 2014, and much more the aesthetic of the SquareOne EKS9 with its R3ACT suspension in 2017. The Collosus retains the development alive, although the general look most likely will not 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 Mt. Bromo to eMTB. The idea is that the 2 decrease counter-rotating brief hyperlinks can be utilized to dictate the trail of the axle, whereas the seatstays and rocker arms are used to regulate the camber curve, or how a lot development there’s. All these hyperlinks could make it simpler for designers to realize their desired suspension traits, nevertheless it additionally means there are 16 cartridge bearings to maintain monitor of, and the bottom set of bearings is positioned straight in entrance of the rear wheel, proper the place mud and grime will find yourself on a messy trip.

Anti-squat percentages are fairly excessive, hovering round 121% in sag earlier than progressively dropping because the bike goes by its journey. Scaling the graph makes the development look fairly excessive, however in actuality it is round 19%, which is fairly typical for an extended journey enduro bike.

Driving impressions

To anybody who says weight does not matter, I encourage you to take the Collosus for a spin. I’ve spent a number of time—years, actually—pedaling round bikes within the 40-pound vary, and I am removed from small, however I will admit that it is slightly tougher to muster the motivation to pedal lengthy on a motorbike this heavy. Who is aware of, possibly I’ve simply softened.

Sure, I understand the Collosus is not some insanely costly carbon fiber surprise bike, and I am prepared to chop it a bit weight-wise given its worth and stable components package, however £39 continues to be fairly hefty. I am unable to assist however surprise how a lot weight and complication could be saved if the tried and true Horst Hyperlink structure was used as an alternative of sticking with the hyperlinks required for the IFS suspension structure?

Weight apart, Colossus working pedals effectively, particularly for a motorbike with 170mm of journey. The suspension is calm sufficient that I did not really feel the necessity to flip the climb swap on the Float X2, and even on the longer tumults of the hearth highway I used to be completely content material to maintain it within the open place. The chainstays are on the shorter facet of the spectrum, however the steep seat angle and relaxed head angle work collectively to maintain the bike from feeling prefer it desires to drag out on steep climbs. Though it is a pretty substantial, relaxed bike, I did not discover it too troublesome to maneuver by tighter corners or extra technical sections – the slow-rolling tires and general load give it a extra subdued really feel when going uphill.

When it is time to get down, the Collosus is not the quickest out of the gate, nevertheless it feels very stable and up for something when it is on top of things. The rear finish is kind of stiff, and that characteristic, mixed with the shorter chainstays, makes it simpler to snap the rear wheel out and in of tight corners, though this comes with barely lowered traction and stability – at instances it felt just like the rear wheel of the Collosus was extra more likely to wheel slide by a twist reasonably than carving a clear arc. It additionally does not have the plushest, fluffiest suspension really feel; it’ll take the sting off the tough stuff, it simply does not erase these greater hits the best way another bikes on this journey bracket do.

General, the Collosus N9 supplies nice worth in the case of components specs, and the geometry will not maintain it again so long as you retain it pointed at steeper, technical trails. Weight is the most important disadvantage, though it might not be an enormous concern for riders who spend most of their time climbing in a shuttle or sitting on a cable automobile.
