Technology

Tapered Seat Tube

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

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.

Smooth Welded

Smooth welds reduce notching and make aluminium frames more durable.

Hydraulic Disc Brakes (Trekking)

Braking power can be perfectly modulated anytime.

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. 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.

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.

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

Bike-Category 4

Cross bikes

This category describes STEVENS cross bikes. They have 28-inch wheels with narrow tyres. The tyre width is 28 to max. 42 mm. STEVENS ALLROUND X Premium, X Cross.

Instructions on intended use

The permissible overall weight (rider incl. baggage and bicycle) should not exceed 130 kg. Under certain circumstances the permissible maximum weight can be further limited by the component manufacturers’ recommendations for use.

STEVENS cross bikes are intended for hard-surface terrain, i.e. for tarred roads and bicycle lanes or gravel field tracks, where the wheels do not lose ground contact. In addition, they are well suited for well paved gravel paths and forest roads as well as off-road trails with a slight slope where a temporary loss of tyre contact with the ground due to small steps may occur. They are not suitable for off-road use (mountain bike use), namely for all mountain, enduro, downhill (DH), freeride, dual slalom, downhill/freeride parks, jumps, drops and in bike parks etc.

Due to their design and fittings, STEVENS cross bikes 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 4 are not suitable for off-road use, jumps, slides, stair riding, stoppies, wheelies, tricks etc.!
