Seven X Programme 2019 - the lightest pure titanium disc frame in the world

"Be in no doubt - 11 ounces or just over 300 grams, is an awful lot of weight to shed in cold blood"

Seven XX Programme

Just over a year ago Seven launched its X Programme with three concurrent goals:

  • Strip out as much weight as possible from its current Axiom/Evergreen SL/SLX frames. To make the lightest ti/disc bikes in the world
  • At the same time ensure there is no negative corollary in ride quality
  • Ensure there would be no negative on Seven's legendary, class-leading longevity and resilience

One Year On

And Seven are as good as their word. The XX generation ride even better than pre-XX bikes - mainly because they are discernibly lighter - be in no doubt - 11 ounces or just over 300 grams, is an awful lot of weight to shed in cold blood, off an already lightweight bicycle frame. In addition Seven has maintained its ten year unblemished record at Cyclefit, with zero warranties or issues at the time of writing. For 2019 Seven have deepened and developed the XX programme - we review in full.
