Seven XX, SL, S

All Sevens are handmade in Boston US, from US milled titanium that is drawn, swaged, butted and shaped in-house. The raw titanium is exactly the same from model to model, but the processes the tubing will go through are dramatically different. In simple terms the more elaborate the tubing processes the more expensive the frame will be - Seven Titanium White-Paper

XX - Can be applied to 622, Axiom or Evergreen. XX is a result of a year long project by Seven founder, Rob Vandermark to re-imagine what is possible with the metal that he knows better than any other person in the world. The context was that the world was moving towards disc-braked bikes, so the frames need to be both stiffer and stronger, but no heavier. No other titanium builder has managed this. But Rob has. XX is the pinnacle of what is possible with superb design and engineering, regardless of cost. Triple-butted, shaved, honed, polished to a fraction of a millimetre. It is important to remember XX frames are still designed to last a true lifetime.

SL - Historically Seven's signature tubeset. SL Denotes that the tubeset is double-butted. All Seven's tube process are completed in house - Seven White Paper - Engineering titanium is ferociously difficult, time-consuming and therefore expensive. SL means that each tube is selected and engineered change the wall-thickness of the tube twice along its length.

S - Seven's S level frames use plain-guage - i.e. non-butted tubes. These frames are perfect for high-mileage tourers or commuter bikes where strength and longevity is more important than weight.

    Time-Triallist (70+)

  • "I tried the shorter cranks today and I like them - it feels like it's less stress for the back and it seems easier to ride higher cadence. In the end I had a good Tour with no back problems. Thanks for your help!"

  • "I had my second fitness test this weekend and on the first 8 minute time trial I'd improved average power output by a whopping 41 watts over the previous test. This is almost entirely down to the new position!"
