Seven XX Upgrade Programme

XX Yourself

The incredible Seven XX Upgrade Programme consists of eleven weight saving gains over the standard Seven Evergreen SL or Evergreen SLX - Through which you will save up to 1/2lb off your frame and fork! The primary design goal with XX was to eliminate weight without sacrificing any frame stiffness, longevity or performance. Only Seven has the titanium experience and engineering skills to achieve this. A Seven Evergreen SLX XX is the lightest titanium disc frame-set in the world.

Technical Spec

Asymmetric dropouts The new asymmetric design is 60 grams lighter, but it’s also stiffer (and Seven’s dropouts are already the stiffest in the industry).
Asymmetric chainstays Complex engineering results in increased drive-train stiffness and weight saving. Win win.
Internal seat post binder Saves up to 75 grams and beautifully minimal.
30.9 mm seatpost sleeve & seatpost Valuable few grams saved - does not negatively affect the ride
More aggressive bottom bracket machining Saves 14 grams - same stiffness and longevity
Super-refined tube butting saves Removes an additional 1.5 ounces, on average - rider specific
Enlarging the frame’s breather holes Saves 12 grams in places a rider never sees. No stiffness or longevity implication
Modified our flat mount brake adaptor Saves 13 grams - with no change in braking response.
Modified, XX specific tube selection process Saves between 30 and 60 grams. By combining tube diameters and wall thicknesses in new ways to take full advantage of Seven's US-milled aerospace-grade titanium

What our clients say

  • "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

  • "A highly personalized and very friendly service, giving good advice and adjustments that are helpful whatever level of cyclist you are."



  • "Rode my standard Box Hill loop this morning with the temp shims and more thought to position. Felt more connected and compact on the bike. Fastest ride of the year, picked up close to a km/per hour despite crappy wet pot holed roads, a ton of traffic and a couple of nights out Thu/Fri."

    Matt H

    Seven Evergreen SL

  • "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."

    Ed H

    London Dynamo Rider

  • "Cyclefit offers an in-depth and highly personalised approach to bike sales. Whatever your riding discipline (for me it’s road, gravel and MTB) the team in Covent Garden will find the right build for you. All this is built around a pro level bike fit and detailed component selection. Add to this the important items often overlooked beyond the bike itself such as shoes, insoles and saddle pressure mapping and it’s a full service operation."
