Fun In Marathons Or On Trails? Colorado 401.

A nicely welded aluminium frame with lots of smart details, the completely new Shimano Deore XT 1x12-speed group including disc brakes, Fox 32 Float suspension fork with lockout remote, thru-axles front and rear - solid ingredients define the Colorado 401. On the trail and in the races you will immediately feel the advantages of STEVENS' trademark agile geometry.

  • Agile and lightweight hardtail made of triple butted aluminium 6061 w/ top-notch specs
  • Classy Fox 32 Float Rhythm suspension fork
  • New Shimano Deore XT 1x12-speed drivetrain w/ extra wide gearing range
  • Powerful Shimano Deore XT disc brakes
  • Fulcrum Red Zone 700 wheels with thru-axles

Technology

Boost-Standard Fork

What is right for the rear wheel is even more important at the front wheel - because steering precision matters. This is why STEVENS uses suspension forks and hubs with extra wide axle spacing for all its fullies, as well as for the trail rocket Sonora and the alloy-hardtails Colorado and Sentiero. These 110mm of axle spacing are called "Boost" or "Plus" and stand for lots of added lateral stiffness plus space for extra wide studded tires.

Boost Rear Axle Spacing

Since model year 2016 the rear stays of all STEVENS fullies adhere to the new "Boost" or "Plus" standard with 148 mm axle spacing. And there are good reasons for that. Rear wheel stiffness increases by 20 % which is especially beneficial in large 29" wheels. And there is more space for voluminous studded tires to give you more control and fun an the trail.

Tapered Seat Tube

The seat tube tapers from top to bottom. At the top it fits a slim 27.2mm seatpost that offers some flex and therefore increases comfort especially when riding over rough ground. At the bottom the large diameter nicley flows into the bottom bracket shell and downtube to provide great stiffness and drivetrain efficiency.

Hydroforming

Using water or oil pressure aluminium tubes are transformed from their original round shape into their ideal shape determined by STEVENS engineers to perfectly withstand any load without any weight penalty. This means better steering precision on the trail and higher longevity.

Versatile cable routing

We keep the cable routing on our bikes as versatile as possible so you can ride your bike like you want to. There are wide and therefore easy to reach cable ports in the frame to insert shift or brake sleeves, Di2 cables or even no sleeves at all - there are the appropriate cover plugs for all of this.

Tapered Steerer / Tapered Headtube

Fork shaft (or steerer tube) and head tube are tapered, meaning their diameter increases from top to bottom resulting in a conical shape. The diameter needs to be bigger at the bottom since this is where higher stress is applied - especially when the bike has a higher total weight due to luggage or an e-drive and battery. Also tapered steerers feature a smoother force transfer (like forces caused by hard braking) to the downtube than forks with a continuous 1 1/8" diameter.

Triple Butted, Double Butted

Meaning a frame tube has three or two different wall thicknesses along its length. Triple butted (TB) is the usual technology with STEVENS high-quality frames.
Tubes with different wall thicknesses are optimally adjusted to certain ways of manufacturing or to withstand specific loads. Where the highest loads occur or where tubes are welded, walls are the thickest. Butted tubes allow frame weight to be lower by several hundred grams.

QR15 Front Thru-Axle

"15" stands for the diameter in millimeters, "QR" for quick release. Combined they are the most useful method to fix the front wheel to the (suspension) fork. With convincing advantages: high stiffness, precise positioning of the brake disc and super-easy handling. So STEVENS specs almost all its mountain bikes and even high-quality trekking bikes, cross bikes and pedelecs with a thru-axle. Additionally, especially with 29" MTBs axle spacing is increased from 100 to 110 mm which makes the design even stiffer.

Smooth Welded

Additional step in welding. The first, rippled weld, typical for aluminium, is covered with a second smoother weld. This not only improves looks but also lowers the risk of notches in this spot, which makes the frames more durable.

Di2-ready

Electronic shifting is already well established in road bikes as well as in mountain bikes next to classic mechanical systems. Impressively fast and reliable gear changes and minimum maintenance pay their dividends not only at the Tour de France, in cyclocross or on the Cross-Country World Cup circuit. That's why STEVENS road bike and MTB frames are "Di2"-ready, meaning they are prepared for an elegant integration of batteries and electric cables (instead of usual wire cables). Even for the classy Alfine gear hub Shimano offers an electronic version.
