Technology

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.

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.

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.

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
