Seven Axiom XX Disc

Strong, Light, Expensive, Comfortable - Pick All Four.


Without being boastful. This bike represents the very best of Cyclefit.

"The satisfying knowledge that technically no more can be done at this time"

Alan's Seven Axiom XX Disc - Mini-Test

Keith Bontrager is about as close as I will ever get to meeting a living genius. He is the bike industry's Richard Feynman - Polymath, physicist, art-house frame-builder, and for the last 20 years or so head of engineering and design at Trek Bicycles. I say all this because he invented the aphorism:
"strong, light, cheap - now pick two"
Time hasn't dulled the internal logic of those six words, and the way he applied them to cycling technology.
But the Seven Axiom XX Disc doesn't so much disprove those words as move the whole debate to a different technical and financial postcode. Seven deliberately set out the Axiom XX stall as performance and quality, regardless of cost. XX for 2019/2020 means all of the technology that Seven has developed over the last twenty years plus all of the most recent XX development in one frame. This frame was, I think, a labour of love for both myself and Alan. It incorporated one of the longest and exacting gestation periods of my 20 year career designing bicycles.

Myself and Alan, were also on a twin-track. This is the bike that I wanted to build for myself and almost certainly now will over the winter. A full titanium, disc-brake frame, made incorporating the finest: materials, fabrication technology and design available at this moment. The satisfying knowledge that technically no more can be done at this time.


Titanium is virtually indestructable but it is still a conversation I would prefer not to have.

Power and Grace

This is a shockingly accomplished bike. Not the lightest - around 7.5kg. Certainly not the cheapest - the frame alone is almost £5,299.00. But the poise, control and tautness from the chassis is class-defining. The 28mm tyres blow out to around 31 on the Enve rims, which gives a Rizla between the back wheel and the seat-stay. This aims the bike uncompromisingly at power-delivery with the inherent properties of titanium as a fall-back plan. It works so well that me and Jules are designing more bikes like this. We are leaning in hard on Seven's skill at engineering in souplesse and life to their topline tubeset, so we can edge the design to be as exciting as possible, without terrifying anyone. For me this frame encapsulates that spirit of controlled aggression. I didn't over-chance my arm - this bike is Alan's once in a lifetime dream. I felt very lucky for the few minutes I had around the streets. But it is enough to tell me that this is the dream I will be building for myself this winter.

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."

    Ed H

    London Dynamo 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."


    New Cyclist

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



  • "Cyclefit provide a great personalised service that focuses on giving you exactly what you need. They are extremely knowledgable and friendly and no request/requirement is too difficult for them."


    Cyclist & triathlete

  • "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."
