2017 Alchemy Arktos



If you scroll through the list of bike names that come out of Alchemy, you’ll quickly get the idea that they must really like their Greek Mythology over there in Denver, Colorado. But don’t get the impression there is anything airy-fairy about how they build their bikes; far from it. When you order an Alchemy Arktos stock mountain bike frame, you’ll be getting a level of craftsmanship and attention to detail that will not only guarantee a plush, robust ride, but will convince you the gods did have something to do with it.

As a full suspension carbon trail bike, the Arktos will be a great all-rounder where you can smash some XC courses or slam some technical downhill passages Since the frame is built around a 27.5 inch wheelset with 150mm of rear travel, you get the best combo of responsive pop-ability while knowing that you won’t get bobble-head syndrome on rough downhills. And if you stick some 2.4 inch tires on, you’ll have traction till next Tuesday. The suspension uses a dual-link platform called Sine Suspension, which is the brainchild of David Earle. Earle has a long history of creating suspension systems for all sorts of clients, many of whom he isn’t allowed to talk about. But the Sine System is exclusive to Alchemy. It takes its name because when the shock wave is graphed, it resembles a sine wave. If you can’t remember what a sine wave actually looks like, it means that the travel is regressive through the first part in order to absorb small bumps, and allowing you to climb without losing energy or grip. The midpoint of the stroke then is progressive to keep you nimble in corners without bottoming out on hard hits. Finally in the last 15% of the stroke, it turns regressive again so you can get the benefit of all six inches of travel. And since the design minimizes chainstay growth, you can still count on pedaling efficiently through rough patches, and if you have to feather or even slam the brakes, your suspension won’t lock up as a result.

The frame has been designed to be compatible with 150mm to 160mm forks, and has rear spacing to accommodate the Boost 148, making this a bike that can hang with the snappiest hardtails on the fire roads, but leave them in the dust once the trail tilts downward. The 73mm threaded bottom bracket guarantees an ease of maintenance as well as durability through all sorts of weather and trail conditions. It also gives you endless choice for cranks. It is an X1 compatible frame, keeping the weight down and the setup simple. Internal routing for the brakes, shifters and dropper post also make sure that the look is clean. After all, one of the big selling points of Alchemy bikes is just how much their paint jobs pop in the sunlight. We’d be less than sincere is we didn’t admit that the hard-candy smoothness and shine is at least part of their appeal. But it is also a sign of just how much care Alchemy takes to make sure every step of the frame building process is pristine.

Any Alchemy Arktos mountain bike frame is going to turn some heads on the trail, so you better be prepared to make sure your technique is up to snuff. The stock version of this frame comes in S, M, L, and XL, so there shouldn’t be any trouble in finding your ideal size.
