bike sehr gut

Great sports-machine and excellent climber. Because of its low weight, the Colorado it's right on top in the 29in league. In a nutshell: Light, agile bike with great marathon specs.

MountainBIKE

Stiff, high-value aluminium frame with high agility in tight corners. Top: Strong forward-drive and good climbing properties.

Tapered Seat Tube

Increases riding comfort and provides stiffness and drive-train efficiency.

Hydroforming

A bonus in steering precision and longevity.

Tapered Steerer / Tapered Headtube (MTB)

Riders benefit from noticeably higher steering precision, almost without weight penalty.

continue reading …

Triple Butted, Double Butted

For light and stable frame: Frame tubes with thinner walls in the middle and thicker walls at the ends.

continue reading …

Anodized Frame (anodized finish)

Anodized frames are very impact-resistant, light and long-lasting.

15 QR-thru Axle Front

Most functional method to fix the front wheel to the (suspension)fork.

E-thru Rear Axle

Thru-axle standard from Shimano for mountain bike rear triangles.

Smooth Welded

Smooth welds reduce notching and make aluminium frames more durable.

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.

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.

Anodized Frames (Anodized finish)

In an electrically charged dipping bath high-quality aluminium frames are covered with a hard, smooth, even surface that looks especially classy in STEVENS Anodized Black. Therefore neither a paintjob nor powder coating is necessary - saving about 200 grams of frame weight.

15 QR Thru Front Axle

"15" stands for 15mm axle diameter, "QR" for quick release, combined they stand for the most functional way to fix the front wheel to the (suspension) fork. This offers decisive advantages: high stiffness, precise brake disc alignement and super easy operation. So STEVENS outfits almost all mountain bikes and even their high-quality trekking bikes, cross bikes and pedelecs with thru-axles.

E-thru Rear Axle

This abbreviation stands for Shimano's thru-axle standard for MTB rear stays that integrates a thread into the dropout. On the majority of STEVENS mountain bikes a 12mm thru axle provides outstanding rear triangle stiffness and utmost precision in brake disc alignement to prevent annoying brake rub.

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.
