Technology

Rohloff Speedhub

14 finely-stepped gears cannot be arranged in amore reliable fashion

Belt Drive

Silent-running, huge life-span, maintenance-free and low weight.

QR15-Steckachse vorn

Die funktionellste Methode, das Vorderrad in der (Feder-)Gabel zu verankern.

Integrated Pannier Rack Strut

Invisibly provides more stability and lateral stiffness.

Hydraulic Disc Brakes (Trekking)

Braking power can be perfectly modulated anytime.

Tapered Seat Tube

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

Anodized Frame (anodized finish)

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

Reifenfreiheit bis 47 mm

Mehr Fahrkomfort und Pannenschutz mit bis zu 47 mm breiten Reifen.

Hydroforming

Optimum load-specific shape by oil or water pressure.

Tapered Steerer / Tapered Headtube

Tapered headtube for optimum force transfer and steering precision.

Triple Butted, Double Butted

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

Adjustable Dropouts

Convenient and exact chain or drive belt tensioning.

Smooth Welded

Smooth welds reduce notching and make aluminium frames more durable.

Rohloff Speedhub

There is no more reliable way to arrange 14 finely-stepped gears than with this great idea from Rohloff. There are Speedhubs out there having run more than 100.000km. And there are thousands of everyday and long-distance riders who never ever want to use any other way of shifting again. Maintenance? Maybe one oil change per year - that's it.

Belt Drive

A belt drive, as the name suggests, uses a drive belt instead of a chain to transfer power from the cranks to the rear wheel. Since the belt cannot be split like a chain the special STEVENS frame utilizes a splittable seat stay, but the advantages are convincing: lower weight, silent operation, almost endless longevity without any maintenance.

QR15-Steckachse vorn

Die „15“ steht für den Achsdurchmesser, das „QR“ für „Quick Release“, also Schnellspanner – und zusammen für die funktionellste Methode, das Vorderrad in der (Feder-)Gabel zu verankern. Die Vorteile sind bestechend: hohe Steifigkeit, präzise Bremsscheiben-Positionierung und kinderleichte Bedienung. Also stattet STEVENS fast alle Mountainbikes und sogar die hochwertigsten Trekking-, Crossbikes und Pedelecs damit aus. Vor allem bei den 29“-MTBs wird sogar noch die Einbaubreite erhöht – von 100 auf 110 mm, das ist noch steifer.

Even when you can't see the strut that connects the pannier rack to the fender - it is there. The strut runs below the fender and provides - in connection with the rack mounted to the fender - more stability and lateral stiffness.

Hydraulic Disc Brakes (Trekking)

There is no more reliable brake system than hydraulic disc brakes - that is why we strongly advice everyone, who is riding their cross, trekking- or city bike 12 months a year to choose one of our models with the „DISC“ suffix. Brake power is easy to modulate and does not fade a bit in the wet. Also the brakes are almost maintenance-free. And your local STEVENS dealer will gladly explain to you what you need to take care of when removing and re-installing a wheel

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.

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.

Reifenfreiheit bis 47mm

Wer häufiger auf Strecken mit weniger glattem Untergrund unterwegs ist, kann bis zu 47 mm breite Reifen montieren – und dann von mehr Fahrkomfort und Pannenschutz profitieren, die deren größeres Luftvolumen mit sich bringt, weil nunmehr mit geringerem Reifenluftdruck gefahren werden kann. Die Rahmen und Gabeln dieser Bikes sind jedenfalls schon darauf vorbereitet.

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. Riders of allround bikes and pedelecs will benefit from a better stability caused by hydroforming even when they are touring with heavy luggage.

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.

Adjustable Dropouts

High quality STEVENS frames equipped with a gear hub or Pinion 18-gear box come with adjustable dropouts. These make correct tensioning of the chain or drive belt very easy. Adjustment via headless set screw and Allen key allows very precise alignement. Two fastening bolts on each side provide tight grip. On bikes with derailleur shifting the chain is tensioned by the derailleur.

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.

Bike-Category 1

City and trekking bicycles

This category describes STEVENS city and trekking bicycles. STEVENS ALLROUND Urban, City Cross, Trekking Premium, Trekking and City as well STEVENS Junior 26 inches.

Instructions on intended use

The permissible overall weight (rider incl. baggage and bicycle) should not exceed 130 kg. Under certain circumstances this permissible overall weight can be further limited by the component manufacturers’ recommendations for use.
STEVENS city and trekking bicycles are designed for a trailer load of 40 kg without and 80 kg with trailer brake.

Due to their design and fittings, STEVENS city and trekking bicycles are not always suitable for being used on public roads. If you want to use them on public roads, these bikes must be fitted with the prescribed equipment. Observe the traffic rules when riding on public roads. For more information see chapter “Legal Requirements for Riding on Public Roads” in your comprehensive STEVENS user manual on the enclosed CD-ROM.

Danger:

STEVENS bicycles of the category 1 are not suitable for off-road use, jumps, slides, stair riding, stoppies, wheelies, tricks etc.!
