The XX, SL, S and Pro
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 Axiom, Sola 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.
What features are included in the XX models?
- Up to 300 grams of weight savings

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. Available in road, gravel or allroad formats.

Seven Pro Carbon-Titanium
New for 2026 - Seven's PRO carbon-titanium frame is the lightest Seven available. Like all Sevens every Pro frame has a lifetime warranty. Every Seven 622 Pro has seven carbon tubes with multi-butted titanium chainstays, and titanium tubed intersections. Each frame is handbuilt in Watertown, Massachusetts. All of the Pro carbon tubes are custom-made for Seven in Utah. All of the titanium is similar for both models.
