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-gauge - 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.

    What our clients say

    • "A great service, full of personal touches as well as the "harder" scientific analysis of my position on the bike, which was also excellent. I feel more planted on the bike now, and came away with some really useful feedback from the session."

      London Dynamo Rider

    • "Very very personalised service. You arrive, they expect you, greet you by first name, have checked your file from past visits and set out very clearly what the process will be, what issues they're looking to address and how and they are happy to take the time to walk you through everything in layman's terms. Almost any professional service entity could learn a lot from how Cyclefit works. "

      Cyclist & triathlete

    • "A very thorough, professional and personal service. I was keen to analyse my bike position after breaking my hip. The custom footbeds and alterations to my position feel really good, just wish I’d come sooner! Many thanks"


      Endurance MTB rider

    • "I'm new to cycling so needed some support on finding a bike that would be right for me. Julian couldn't have been kinder or more supportive, he took time to find out what I wanted from my cycling and then looked closely at my physical structure to ensure that the bike is a comfortable fit for me. It really is a 5 star service and far exceeded my expectations."
