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.

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.

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.

Ganzjahres-Tauglichkeit

Systemlaufräder

Cyclocrosser sind echte Allround-Sportgeräte. Aber noch ganzjahres-tauglicher werden sie, wenn sich an Rahmen und Gabel auch noch vollformatige Schutzbleche montieren lassen. Dann genügt nämlich eine funktionelle Garderobe nach dem „Zwiebelprinzip“, um auch bei den typischen widrigen Bedingungen von Herbst und Winter jede Menge Fahrspaß zu genießen oder sich an noch mehr Tagen im Jahr auf den sportlichen Weg an den Arbeitsplatz zu begeben.
